Tensitron Product FAQ

What is the Tensitron STX-Plus?

The STX-Plus is Tensitron’s next-generation digital strap tension meter, built to measure the tension in strapping and other stationary banding materials so you can confirm loads are secured correctly. It is a smart, connected, handheld instrument designed for one-handed operation, with a multi-screen color display and built-in data storage. It builds directly on the proven STX-1 platform, adding faster operation, Wi-Fi data transfer, and USB-C charging.
Tensitron STX Plus digital strap tension meter for accurate strap tension measurement
It measures the static (stationary) tension in straps, bands, twine, wire, and similar materials, the holding force that keeps a load tight. Readings are taken on materials that are not moving, making it ideal for verifying strap tension on finished pallets and shipments or checking band saw blade tension before cutting. It is purpose-built for quick, accurate static tension verification on the production floor and during routine inspections.
Yes. Tensitron has manufactured precision tension measurement instruments in the USA since 1935, and the STX-Plus is a Made-in-USA instrument backed by that heritage. The same experienced technicians who build the instruments also calibrate and service them in-house.
The STX-Plus is used across packaging, shipping, warehousing, agriculture, and general industrial operations. Common uses include verifying strap tension on truck, rail, and warehouse shipments, checking pallet and carton strapping to prevent crushed or loose loads, confirming baling twine and wire tension in agricultural packaging, and checking band saw blade tension to protect cutting accuracy and blade life. Companies such as American Woodmark and Kingspan use Tensitron STX meters to standardize strap tension and reduce product damage.
Yes. Checking band saw blade tension is a core STX-Plus application; proper blade tension helps maintain cutting accuracy, reduces blade wear, and prevents premature blade failure. Because it handles stiff, stationary materials, it works well for fence wire and saw blades in addition to conventional strapping.

The STX-Plus measures from 1 lb to 2,000 lb on stationary materials. For the full specification set, download the STX-Plus Data Sheet from the product page.

What units of measurement does the STX-Plus display?

The STX-Plus offers selectable units of pounds (lb), kilograms (kg), or decanewtons (daN), so you can match your existing quality documentation and work instructions without manual conversion.

The STX-Plus offers selectable units of pounds (lb), kilograms (kg), or decanewtons (daN), so you can match your existing quality documentation and work instructions without manual conversion.

The STX-Plus is accurate to ±2% of full scale for custom-calibrated models; pre-configured STXM models are ±3% to ±4% of full scale depending on the model. Because accuracy is full-scale based, choosing a range close to your working tension keeps absolute error as small as possible. Each meter ships with a NIST-traceable calibration certificate from Tensitron’s in-house, ISO/IEC 17025-accredited calibration. The meter also ships with an operating manual, available for download from the Tensitron software page.

The STX-Plus is a lightweight, portable instrument in a durable, industrial-grade housing, designed for one-handed use. It accommodates straps up to 4 in wide and 1/4 in thick. What strap and band materials does the STX-Plus work with? The STX-Plus is designed for versatility across poly (plastic) and metal strapping, woven materials, nylon tie-down straps, and stiff stationary materials such as fence wire and saw blades. It accommodates straps up to 4 in wide and 1/4 in thick.
Yes. The meter can be custom-calibrated for your specific straps, or set up using a standard menu of commonly used strap sizes. Custom configurations for specific straps and materials are a standard STX-Plus feature, which keeps readings accurate to the exact material you run.
The STX-Plus is built for quick, intuitive, one-handed operation; you engage the strap and read the tension directly on the multi-screen color display. A tolerance bar on the display gives operators an at-a-glance pass/fail indication against your target range, so even non-technical staff can verify tension reliably. Each unit ships with a carrying case, a NIST-traceable calibration certificate, and an operating manual (available for download from the Tensitron software page).
The STX-Plus charges over USB-C with a universal charger and offers extended battery life with a customizable sleep mode to conserve power between readings. Contact a specialist if you need exact battery specifications for your duty cycle.
The STX-Plus is a smart, connected instrument that stores up to 60,000 readings, transfers data over Wi-Fi for fast integration with your quality system, and provides automated calibration and verification reminders plus maintenance reminders. It has a multi-screen color display with a tolerance bar, selectable units, and customizable sleep mode, all aimed at faster results and instant traceability for audits.
Readings transfer either over Wi-Fi or through a data cable connected directly to your computer, using the Tensitron Data Transfer Application (TDTA), a Windows software package you download from the Tensitron software page. After installing, you register the device using the serial number from the meter’s startup screen and a registration code provided by Tensitron, which then lets you pull stored readings and statistics for traceability and audit records.
Both are on the Tensitron software page. You can download the STX-Plus software (Tensitron Data Transfer Application, a Windows installer) and the STX-Plus operating manual there; the same page contains step-by-step device registration instructions.
The STX-Plus builds on the trusted, proven STX-1 platform and delivers a faster, simpler digital tension-testing experience. Key additions over the STX-1 include Wi-Fi data transfer, USB-C charging with a universal charger, storage for up to 60,000 readings, a multi-screen color display with tolerance bar, automated calibration/verification and maintenance reminders, and a customizable sleep mode. If you run an STX-1 today, the STX-Plus is the direct upgrade path.
Yes. Tensitron periodically runs an STX Trade-Up Program that gives you trade-in credit toward the next-generation STX-Plus, with the goal of a simple, no-disruption upgrade. Trade-in availability and deadlines vary, so check the current STX Trade-Up Program page or contact a specialist for the latest terms.
Choose the STX-Plus when your job is strapping and banding tension: poly/metal strap, woven and nylon tie-down straps, twine, fence wire, and band saw blades up to 4 in wide and 1/4 in thick. Other Tensitron meters target different jobs: the BTX is for flat drive belts and wide tape, the LX for coil winding and fiber optic, and the ACX for aircraft and stationary cables. If you are unsure which fits your material and range, a Tensitron specialist can confirm the right model.
Confirm three things: your strap material (poly, metal, woven, nylon, twine, wire, or blade), its width and thickness (the STX-Plus handles up to 4 in wide and 1/4 in thick), and your target tension (the STX-Plus range is 1 lb to 2,000 lb on stationary material). Share those details with a Tensitron specialist and they will confirm fit and recommend a custom calibration or a standard strap-size menu setup.
Yes. The STX-Plus can be custom-calibrated for your exact straps, or delivered configured with a standard menu of commonly used strap sizes. Specify your strap details when you request a quote so the unit arrives ready to use for your application.

Request a quote through the Tensitron contact form, call (303) 702-1980, or email sales@tensitron.com. You can also order through an authorized Tensitron reseller. Provide your strap type, dimensions, and target tension so the team can quote the correct configuration and any custom calibration.

Standard lead time is typically within two weeks, depending on configuration and whether a custom calibration is required. Confirm the current estimate for your build when you request a quote at (303) 702-1980 or sales@tensitron.com.

Tensitron service includes annual calibration, so a yearly recalibration cycle is the standard recommendation, and the STX-Plus has built-in automated calibration and verification reminders to keep you on schedule. Your required interval may be tighter depending on your quality system or audit requirements.
Yes. Every STX-Plus ships with a NIST-traceable calibration certificate. Tensitron performs all calibration in-house under its ISO/IEC 17025 accreditation, with NIST-traceable standards and documented procedures, and a NIST-traceable certificate is provided with each serviced instrument.

For full details on Tensitron’s accreditation and traceability program, see the Certifications & Traceability page. Tensitron tension meters are also CE and RoHS compliant.

What is the Tensitron ACX?

The Tensitron ACX is a handheld digital cable tension meter built to verify the static tension of aircraft control cables and other stationary cables up to 1/4″ in diameter. It is used worldwide by MROs and manufacturers to support aircraft maintenance and manufacturing, giving technicians a fast, repeatable way to confirm cable tension during installation, inspection, and routine maintenance. Tensitron has manufactured precision tension measurement instruments in the USA since 1935, and the ACX is made in the USA and backed by in-house, NIST-traceable calibration under Tensitron’s ISO/IEC 17025 accreditation. Tensitron tension meters are also CE and RoHS compliant.
Tensitron ACX aircraft cable tension meter for accurate aircraft cable tension measurement
The ACX measures static (steady-state) tension in a cable — the force the cable is carrying — by reading the deflection of the cable as it passes through the meter’s measuring head. Tension is reported on a digital display, typically in pounds (lb) for aircraft and stationary-cable work. Confirm the exact displayed units and full tension range per model on the ACX Data Sheet.
The ACX is designed for aircraft cables and other stationary cables up to 1/4″ (0.25″) in diameter. Tensitron calibrates each meter for specific cable sizes within that range, and calibrations for additional cable sizes are available upon request. For specialized or non-standard cable, Tensitron offers custom calibrations.
The ACX is accurate to ±2% of full scale for all models except the ACX-1200-SCB, which is ±3% of full scale. Accuracy is maintained against standards that are fully traceable to NIST, and the meter is calibrated for the specific cable sizes you intend to measure. For the tightest results, always use the meter on the cable size(s) it was calibrated for.
Cable tension meters read tension indirectly by deflecting the cable, so the relationship between deflection and tension depends on the cable’s diameter and construction. Because of that, the ACX is calibrated for specific cable sizes and cable construction, and using the correct calibration for the cable you’re measuring is essential for an accurate reading. If you work with several cable sizes, Tensitron can calibrate the meter across those sizes, and additional or custom calibrations are available on request.
Select the calibration for the cable size you’re measuring, place the meter onto the cable so the cable seats in the measuring head, and engage the meter to deflect the cable; the digital display then shows the tension. Because the ACX measures static tension, take the reading with the system at rest and in its normal operating configuration. Confirm the exact engagement sequence and any zeroing procedure on the ACX Data Sheet or user manual.
The ACX is widely used in aviation and related fields, including military aviation (control cables and structural cable systems), private/general aviation, and commercial aviation MRO operations, as well as automotive cable systems. It is also used for non-aircraft stationary cables — Anduril uses the ACX-250-1 to measure support-cable tension on surveillance towers, and PSA Airlines uses the ACX-250-1 to inspect flight-control-cable tension. Anywhere a static cable up to 1/4″ needs verified tension, the ACX fits.
The ACX is designed for the static aircraft-control-cable tension verification that cable rigging and maintenance require, and it is used by MROs and airlines such as PSA Airlines for flight-control-cable inspection. Its NIST-traceable, ISO/IEC 17025-based calibration supports the documentation and traceability expectations of aviation maintenance programs. Tensitron’s pages do not explicitly cite a specific FAA advisory circular, so confirm applicability with Tensitron before relying on the ACX for a regulated task.
Both the ACX and the ACM measure static tension on aircraft and stationary cables up to 1/4″ diameter, but the ACX is a digital meter with a digital readout, while the ACM is a mechanical/analog cable tension meter. The digital ACX is generally faster and easier to read, supports data output options, and removes the interpolation a mechanical dial can require; the mechanical ACM needs no battery. Service pricing also differs — standard digital tension meter service starts at $299, while standard ACM mechanical service starts at $329; request a current quote, as pricing should be confirmed with Tensitron.
The ACX is Tensitron’s digital meter purpose-built for aircraft and stationary cables up to 1/4″. Other Tensitron digital meters target different materials and ranges — the CX for tower-rigging and elevator cable, the WX for fabric and plastic film, the TX for small wire/fiber and sutures, and the STX-Plus for strapping and band-saw blades. If your application is aircraft control cables or similar stationary cable up to 1/4″, the ACX is the right family; for heavier structural cable or different materials, a specialist can point you to the correct model.
Tensitron is the original manufacturer and performs all calibration in-house — the same experienced instrument makers who build the meters also calibrate and service them. Calibrations follow documented internal procedures certified to ISO/IEC 17025:2017, and all measurements are fully traceable to NIST; a NIST-traceable certificate is provided with each serviced instrument. Calibration weights are third-party certified every 5 years, and cables used in calibration are inspected at least annually for dimensional tolerance per MIL-DTL-83420N, Table 1.
The ACX carries a one-year warranty against factory defects. The instrumentation is RoHS-compliant (EU Directive 2011/65/EU with amendment 2015/863/EU) and covered by a CE Declaration of Conformity and FCC emissions/immunity testing, with documentation available on Tensitron’s certifications page. Combined with ISO/IEC 17025:2017 calibration practices and NIST traceability, this supports use in regulated maintenance and quality programs.
If you send a meter for service or calibration and choose not to proceed, Tensitron assesses a $100 evaluation fee, which (with the return shipping fee) must be paid before the meter is returned. A storage fee also applies if a meter remains at the facility more than 30 days from the estimate date — $25 initially, then $10 per week thereafter — and meters with no customer communication within six months of the estimate are considered abandoned and discarded. Approving the estimate promptly via PO or payment avoids these fees.
Tensitron recommends annual calibration to keep the ACX measuring accurately. To send a meter in, complete the online service form (no RMA number required) and ship the meter to 135 Industry Drive, Pittsburgh, PA 15275. Standard digital tension meter service starts at $299 (certain specialty ACX meters are $339); request a current quote to confirm the price for your model. Service includes annual calibration plus completely dismantling, cleaning, rebuilding, calibrating, and certifying the meter, with expedited service available for an additional fee. For service questions, contact service@tensitron.com or (303) 702-1980.
Request pricing through Tensitron’s contact/quote form, by calling (303) 702-1980, or by emailing sales@tensitron.com; a specialist will confirm the model, cable-size calibrations, and output option for your application. Because each ACX is calibrated to your specified cable sizes, providing those details up front speeds the quote. Standard lead time is typically within two weeks.
Specify the cable size(s) you measure (up to 1/4″), the tension range/capacity you need, and the data-output option (Analog “A” or RS-232 “E”); these determine the model and measuring-head width. If you handle multiple cable sizes or non-standard cable, ask about additional and custom calibrations. The fastest path is to talk with a Tensitron tension meter specialist, who can match the model to your application requirements.
The ACX is a compact handheld instrument. Its measuring-head width depends on capacity: models up to 250 lb are about 3.4″ wide, and models above 250 lb are about 5.2″ wide. Combined with its rechargeable battery and worldwide charger, the ACX is built to be durable, repeatable, and easy to transport in demanding maintenance environments. Confirm overall dimensions, weight, and kit contents from the ACX Data Sheet.
The ACX uses a rechargeable NiMH (nickel-metal-hydride) battery — not lithium-ion — that provides up to 8 hours of use per charge. The included power supply accepts 100–240V input and ships with interchangeable adapters for US, European, Australian, and other plug configurations, so the same meter can be charged worldwide. This makes the ACX practical for MRO teams and field technicians who travel.

What is the Tensitron CX and what does it measure?

The Tensitron CX (CX-1) is a heavy-duty digital tension meter that measures the tension in cables, wire rope, and other flexible materials. It is designed to safely install or monitor cables so you can achieve consistent tension, avoid mechanical stress, and minimize the risk of cable damage. Tensitron has manufactured precision tension measurement instruments in the USA since 1935.
Tensitron CX-1 cable and wire rope digital tension meter for accurate cable tension measurement
Yes. The CX is a digital meter that measures both static and dynamic tension, allowing you to quickly install, test, and monitor cables, wire rope, and other materials. This makes it suitable both for one-time installation checks and for ongoing condition monitoring.
The CX is available with either an Analog Output (Option A) or an RS-232 Serial Output (Option E). The RS-232 option is useful when you want to log readings or feed data into software or a SCADA-type monitoring system. Specify the output option you need at the time of order.
The CX is built for tower rigging and structural cable work, including catenary systems, elevator maintenance, telecommunications cables, guy wire, zip lines, and theater/stage rigging. In structural and rigging systems, accurate tension keeps support cables within safe operating limits and maintains stability. The CX lets technicians quickly verify tension during installation, inspection, and routine maintenance.
Yes. Communication towers and structural rigging systems depend on properly tensioned cables to maintain structural stability, and the CX is intended for exactly this work. In a published Tensitron case study, the Toho Water Authority used a Tensitron CX to measure tower guy-wire tension and maintain stability across its SCADA infrastructure.
Yes. Elevator systems depend on precisely tensioned cables for safe, smooth operation, and measuring cable tension helps maintain system balance, reduce wear, and ensure reliable performance in commercial and industrial elevators. The CX is one of the meters Tensitron lists for elevator-maintenance tension checks.
The CX checks the tension on flexible cables from 1/16 inch up to 3/4 inch in diameter. This wider diameter capacity is a key reason the CX is chosen for heavier structural, rigging, and elevator cables rather than thin aircraft control cables.
The CX is custom-calibrated to each material it measures, so its tension range is set to match the specific cable and load you specify rather than a single fixed range. Confirm your required maximum load and the units you need (for example lb or N) with a Tensitron specialist when ordering. Confirm the exact tension range and display units for your configuration.
The CX is accurate to ±2% of full scale. Tensitron notes that accuracy may differ depending on the material being measured, which is one reason each unit is custom-calibrated to the specific cable.
The CX is a digital tension meter, so readings are shown on a digital readout rather than an analog dial. Confirm the exact display type, resolution, and backlighting on the CX Data Sheet.
Because the CX is custom-calibrated for each material, Tensitron needs a 10-foot sample of each cable to be measured, and up to 10 calibrations can be loaded onto a single meter. Tensitron maintains an extensive library of cables. Providing the samples promptly helps avoid delays. Standard lead time is typically within two weeks once samples are received.
The CX is a portable, handheld digital meter intended for field use. Confirm the exact battery type and runtime for the CX before quoting; Tensitron’s related ACX model uses a NiMH rechargeable battery rated up to 8 hours per charge, but the CX figure should be verified.
Standard CX-1 rollers are flanged, with a 7/8-inch outside diameter and a 3/4-inch working length. For flat materials, 2-inch or 3-inch cylindrical rollers are available as Option R. Choose the roller configuration that matches the cable or material profile you measure.
Yes — the CX is designed as a durable, easy-to-transport instrument for demanding field work such as tower rigging, structural cable, and elevator maintenance. Its durable construction is highlighted as a way to save time and cost while improving safety and performance in the field. Confirm any specific IP/environmental rating or operating-temperature spec on the CX Data Sheet.
The CX measures cable tension by engaging the cable across its three rollers, so the meter reads the deflection that corresponds to tension; you then read the value directly from the digital display. Because each CX is custom-calibrated to your specific cable, you must use the meter with the same material and roller setup it was calibrated for to get accurate results. Confirm the exact step-by-step measurement procedure in the CX manual or Data Sheet.
Choose the CX for heavy-duty cable and wire-rope work — tower rigging, structural cable, guy wire, catenary, and elevator cable — where diameters run up to 3/4 inch. The ACX is purpose-built for aircraft and other stationary cables up to 1/4 inch in diameter, so it is the better fit for flight-control cable and lighter stationary cable. In short: pick the CX for larger structural/rigging cable, and the ACX for thin aircraft-grade cable.
Tensitron makes a family of meters for different materials — for example the WX for fabric and plastic film, the TX for small wire/fiber and sutures, the STX-Plus for strapping and band-saw blades, and the LX for coil and fiber optic. The CX is the model dedicated to tower rigging and elevator/structural cable. If your material falls outside cable and wire rope, a different model in the lineup is likely the better match.
Specify the cable type and material, the diameter (within the 1/16-inch to 3/4-inch range), your maximum expected tension and preferred units, the data output you want (analog Option A or RS-232 Option E), and your roller needs (standard flanged or Option R cylindrical for flat materials). Because the CX is custom-calibrated, sharing these details up front ensures it arrives calibrated for your exact application. A Tensitron specialist can confirm the configuration before you order.
Request a quote through the Tensitron contact form or by speaking with a tension meter specialist, who can confirm the right configuration for your cable type, industry, and application. You can reach the team at (303) 702-1980 or sales@tensitron.com. Have your cable details ready (type, diameter, expected tension, output, and rollers) to speed up the quote.
Each CX-1 is custom-calibrated for the specific material it will measure, and up to 10 calibrations can be stored on one meter. A 10-foot sample of each material may be required for calibration. This per-material calibration is what allows the CX to hold ±2% of full-scale accuracy across different cables.
Tensitron recommends annual calibration to maintain measurement accuracy and reliability, and a standard service includes that annual calibration. Tensitron also publishes guidance on calibrating your tension meter annually to protect what’s on the line. Build a yearly recalibration cycle into your maintenance schedule to keep readings trustworthy.
Yes. Tensitron performs all calibration in-house under its ISO/IEC 17025 accreditation, with NIST-traceable standards and documented procedures, and a NIST-traceable certificate is provided with each instrument. For full accreditation scope and certificate details, see Tensitron’s Certifications & Traceability page. Tensitron tension meters are also CE and RoHS compliant.
Complete the online service form, then package and ship the meter to Tensitron at 135 Industry Drive, Pittsburgh, PA 15275 — no RMA number is required.

What is the Tensitron LX-1 tension meter?

The LX-1 is a digital, handheld tension meter designed to accurately measure tension on a wide range of flat or round materials, whether they are moving or stationary. It is built for manufacturing, inspection, and quality-control environments where tension consistency matters, delivering reliable, repeatable readings. Tensitron has manufactured precision tension measurement instruments in the USA since 1935.
Tensitron LX-1 cable and wire tension meter for measuring wire, cable, tape, and bands
The LX-1 measures copper wire from 1 to 19 AWG, tape or bands up to 1 inch wide, steel wire up to 0.08 inch, and braided cable up to 1/4 inch. This versatility makes it suitable for coil winding, EDM wire, textile manufacturing, and other industrial applications. Because it reads both moving and stationary material, you can use it during setup and during active production.
Yes. The LX-1 provides digital static and dynamic tension measurement, so operators can monitor tension during initial setup as well as during active production runs on moving wire or cable. Measuring tension on running material helps catch drift before it turns into scrap.
Accurate tension control is critical during coil winding for electronics, transformers, and electrical components, where proper tension ensures consistent winding and a higher-quality finished coil. The LX-1 lets winders verify and document the tension being applied to the wire rather than relying on machine settings alone. It covers copper wire from 1 to 19 AWG, the range typical of many coil-winding operations.
Yes. Communication towers and structural rigging systems depend on properly tensioned cables to maintain structural stability, and the CX is intended for exactly this work. In a published Tensitron case study, the Toho Water Authority used a Tensitron CX to measure tower guy-wire tension and maintain stability across its SCADA infrastructure.
Yes. The LX-1 has a lightweight, portable, and durable design and is described as user-friendly and easy to transport, making it convenient to carry between machines or to a customer site. It runs on a rechargeable NiMH battery rated for up to 8 hours of continuous use per charge, so it does not need to be tethered to power on the floor.
Typical applications include coil winding, communications and electrical cable, fiber optic cable, rope and cord, and flexible tubing for industrial and medical use. Manufacturers such as Whitney Blake and BizLink use Tensitron LX-series meters to verify wire and cable tension during production and maintain consistent quality. If you tell a specialist your material and tension target, they can confirm fit.
The LX-1 is offered in defined load ranges (for example, the LX-25-1 referenced in Tensitron’s BizLink case study), and the model number reflects the full-scale rating. The exact full-scale tension value and engineering units for your configuration are listed on the LX Data Sheet and confirmed at quote. Confirm the exact full-scale range and units for the specific LX model with Tensitron.
The CX is accurate to ±2% of full scale. Tensitron notes that accuracy may differ depending on the material being measured, which is one reason each unit is custom-calibrated to the specific cable.
The LX-1 has a digital readout and offers two data-output options: Analog Output (Option A) or RS-232 Serial Output (Option E), so readings can be logged or fed to other equipment. Specify the output option you need when ordering. The exact display type and resolution are detailed on the LX Data Sheet.
You route the wire, cable, or band through the meter’s three-roller head, then read the tension directly on the digital display while the material is held or running. Because the LX-1 reads both static and dynamic tension, you can capture a value on stationary material during setup or on moving material during production. For best repeatability, follow the threading and zeroing steps in the LX manual and use a meter that is within its calibration interval.
A compact, durable, battery-powered meter lets one operator check tension at multiple stations or machines without moving the work or running cables to a power source. With up to 8 hours of continuous use per NiMH charge, the LX-1 supports a full shift of spot checks and audits. Portability also makes it practical for field-service technicians who need to verify tension at a customer site.
Choose the LX-1 for medium wire and cable work — copper wire 1 to 19 AWG, tape or bands up to 1 inch, steel wire up to 0.08 inch, and braided cable up to 1/4 inch — especially in coil winding, EDM wire, fiber optic, and textile manufacturing. For smaller wire, fine fiber, or sutures, look at the TX; for heavier cable, wire rope, tower rigging, or elevator cable, look at the CX; for aircraft cable, look at the ACX or ACM. A specialist can match the meter to your material diameter and tension target.

Specify three things: the material type and dimension (AWG, width, or diameter), your target tension and its acceptable tolerance, and whether the material will be moving or stationary. Also choose your data-output option — Analog (Option A) or RS-232 (Option E). Sharing these details with a Tensitron specialist, or referencing the LX Data Sheet, ensures the model and full-scale range fit your process.

Use the Get a Quote / Contact Us form on the LX page, call (303) 702-1980, or email sales@tensitron.com to reach a specialist. Tell them your material, tension target, and required output option so they can quote the correct LX configuration. Standard lead time is typically within two weeks.

This per-material calibration is what allows the CX to hold ±2% of full-scale accuracy across different cables.

What is the Tensitron ACM?

The Tensitron ACM is a mechanical (analog) aircraft cable tension meter used to quickly and accurately verify the tension in flexible cables. It reads tension directly on an analog dial with no batteries or power required, and it has built-in cable selection so you do not have to fumble with loose risers. Tensitron has manufactured precision tension measurement instruments in the USA since 1935, and the ACM is its field-proven analog verification tool for aircraft and automotive cable work.
Tensitron ACM mechanical cable tension meter for accurate cable tension measurement
The ACM measures the static tension in a flexible cable — the pulling force carried along the cable, expressed in pounds (lb). It does this by deflecting the cable a known amount between three contact points and translating that deflection into a tension reading on the dial. This lets technicians confirm a control or structural cable is rigged within its correct tension range during installation, inspection, and routine maintenance.
ACM instruments are designed to measure flexible cables with diameters from 1/16″ up to 1/4″, CWT (cable size) numbers from 5 to 25, and tension from 5 to 600 pounds. Specific models cover sub-ranges — for example 5–100 lb up to 40–600 lb, plus CWT-marked models at 10–150 lb and 40–300 lb. Calibrations for other cable sizes are available upon request.
The ACM is fully mechanical, so its analog dial requires no power and there are no batteries to die in the field, in tight spaces, or on the flight line. That makes it durable, simple, and dependable for technicians who want a rugged verification tool that is always ready to read. It is the right pick when you value no-battery reliability, simplicity, and a proven analog instrument over digital data capture.
The ACM uses durable mechanical construction designed to hold up to repeated field use, which Tensitron positions as a way to save time and cost over the life of the instrument. Because it has no electronics or power source, there is less to fail in hangars, shops, or vehicle bays. It is also compact and easy to transport for on-aircraft and on-vehicle work.
The ACM is used to verify aircraft control-cable and structural-cable tension during installation, inspection, and routine maintenance — the core task of keeping aircraft flying safely. Tensitron lists it across military aviation (control and structural cable systems), private/general aviation (routine tension verification), and commercial aviation MRO (maintenance, repair, and overhaul). It is ideal for aircraft cables or other stationary cables up to 1/4″ in diameter.
Yes. Tensitron lists automotive cable systems — the testing and verification of control cables used in vehicle mechanisms — as a primary ACM application. The same one-handed, no-power reading process that suits aircraft control cables applies to automotive control-cable verification.
Yes. Tensitron describes its tension meters as letting technicians and maintenance teams quickly verify cable tension during installation, inspection, and routine maintenance. The ACM’s compact, one-handed operation is built for repeated checks in tight spaces over the service life of the equipment.
Tensitron states ACM accuracy of ±4% to ±8% of full scale, depending on the model. As an analog instrument, the exact figure depends on the specific model and range you select; it is recorded on the calibration certificate supplied with the meter. The meter also ships with an operating manual, available for download from the Tensitron software page.
The LX-1 has a digital readout and offers two data-output options: Analog Output (Option A) or RS-232 Serial Output (Option E), so readings can be logged or fed to other equipment. Specify the output option you need when ordering. The exact display type and resolution are detailed on the LX Data Sheet.
CWT refers to standardized cable-size numbers (the site cites CWT sizes from 5 to 25) commonly used for aircraft control cables. Some ACM models are calibrated and marked specifically for CWT cable sizes — for example the 10–150 lb and 40–300 lb CWT models — so the meter matches the cable callouts a technician works with. If your cables are specified by CWT number, choose a CWT-marked ACM.
The ACM has built-in cable selection, so there are no loose risers to swap, lose, or fumble with — a key practical advantage over meters that use separate riser sets. You select the cable size on the meter itself, then take the reading. Both inch and CWT sizes are supported by the built-in selection.
Operation is quick, easy, and one-handed, and the meter is compact enough for tight spaces. You set the built-in cable selection for your cable size, position the meter on the cable, and read the tension directly off the analog dial. A Memory Lock Pointer holds the reading so you can read it after withdrawing the meter from a hard-to-reach area, and the calibration chart attached to the meter helps you convert the reading for your specific cable.
The Memory Lock Pointer is a feature that holds the dial reading in place, which is especially useful when measuring in hard-to-reach areas where you can’t see the dial during the measurement. The calibration chart is attached directly to the meter so the reference you need to interpret the reading travels with the instrument. Each ACM also ships with a NIST-traceable calibration certificate.
The ACM is the mechanical/analog meter and the ACX is Tensitron’s digital meter; both are aimed at aircraft cables and other stationary cables up to 1/4″ in diameter. The ACM gives you no-power, no-battery analog reliability with a simple direct dial reading, while the ACX adds digital features. Choose the ACM when durability, simplicity, and battery-free operation matter most; choose the ACX when you want digital readout or data capabilities.

What is the Tensitron TX-1 tension meter?

The TX-1 is a handheld digital tension meter built for measuring tension in fine wire and filaments during manufacturing, quality control, and R&D. It provides quick, one-handed verification of tension on delicate materials where consistency is critical, with an easy-to-read digital display and a color-bar graphic for a fast visual of tension. Tensitron has manufactured precision tension measurement instruments in the USA since 1935.
Tensitron TX-1 digital tension meter for wire, fiber, and filament tension measurement
The ACM measures the static tension in a flexible cable — the pulling force carried along the cable, expressed in pounds (lb). It does this by deflecting the cable a known amount between three contact points and translating that deflection into a tension reading on the dial. This lets technicians confirm a control or structural cable is rigged within its correct tension range during installation, inspection, and routine maintenance.
The material is routed across three rollers on the meter head, and the deflection of the center roller is converted to a tension reading shown on the digital display. The instrument can measure both static and dynamic (moving) tension, and a built-in data-averaging function smooths readings in fast-moving applications. Built-in material/diameter selection lets operators measure efficiently without manual charts or complex setup.
Yes. Medical manufacturing — surgical sutures, bandages, and other medical fibers — is a core application Tensitron calls out for this material class, where reliable tension measurement helps ensure material strength, consistency, and product safety. The TX-1 is designed for delicate and precision materials including flexible medical materials, fine wire, yarn, and narrow fabrics. For suture work, the right model is typically the lowest-range TX-125-1 (0–125 g); confirm your exact tension window with a specialist.
Yes — coil winding of fine wire used in electronics, transformers, coils, and micro-components is a primary TX-1 application, and proper tension helps prevent wire stretching, breakage, and uneven coil formation. Real customers use it this way: Climco Coil improved coil production consistency with the TX-5000-1, and Endicott Coil uses Tensitron meters to monitor magnet-wire tension during winding. A mounting bracket (Part No. TR-700, with magnetic base) is available for hands-free use on a winding line.
Yes. Wire EDM machining requires extremely consistent wire tension to maintain cutting accuracy and prevent wire deflection and breakage; there is a dedicated TX-5EDM-1 model calibrated for 0.10, 0.15, 0.20, 0.25, and 0.30 mm EDM wire. For textiles, the TX-1 supports accurate tension monitoring of delicate fibers during spinning, weaving, and processing to maintain fiber integrity and uniform fabric quality.
Across the TX-1 series, ranges span from 0 to 5,000 g depending on model: TX-125-1 covers 0–125 g, TX-1000-1 covers 10–1,000 g, and TX-5000-1 and TX-5EDM-1 cover 50–5,000 g. For larger materials or higher tension than 5,000 g, Tensitron points users to the LX-1 meter instead. Choosing the model whose range brackets your working tension gives the best resolution at low tensions.

The standard menu includes an extensive range of filament and copper-wire diameters for fast setup.
CWT refers to standardized cable-size numbers (the site cites CWT sizes from 5 to 25) commonly used for aircraft control cables. Some ACM models are calibrated and marked specifically for CWT cable sizes — for example the 10–150 lb and 40–300 lb CWT models — so the meter matches the cable callouts a technician works with. If your cables are specified by CWT number, choose a CWT-marked ACM.
The TX-1 runs on a rechargeable NiMH battery (nickel-metal hydride — not lithium-ion) that delivers up to 8 hours of continuous use per charge. The included power supply accepts 100–240V input and ships with interchangeable adapters for US, European, Australian, and other plug configurations, so it works on international lines.
Operation is quick, easy, and one-handed, and the meter is compact enough for tight spaces. You set the built-in cable selection for your cable size, position the meter on the cable, and read the tension directly off the analog dial.

What is the Tensitron BTX-1 and what does it measure?

The WX is a portable digital tension meter built to measure the running or static tension of wide, flat materials such as fabric, paper, plastic film, plastic sheet, metal foil, and conveyor belts. It is designed for web-handling and converting environments where consistent tension is critical to process control and product quality. Like all Tensitron instruments, it is made in the USA; Tensitron has manufactured precision tension measurement instruments in the USA since 1935.
Tensitron BTX-1 band tension meter for measuring strap, belt, webbing, and tape tension
The ACM measures the static tension in a flexible cable — the pulling force carried along the cable, expressed in pounds (lb). It does this by deflecting the cable a known amount between three contact points and translating that deflection into a tension reading on the dial. This lets technicians confirm a control or structural cable is rigged within its correct tension range during installation, inspection, and routine maintenance.
Yes — Tensitron has manufactured precision tension measurement instruments in the USA since 1935, giving the BTX nearly a century of engineering heritage behind it. That experience is reflected in the meter’s durable construction and the fact that the same technicians who build the instruments also service and calibrate them.
The BTX-1 is ideal for narrow, flat materials including nylon straps, seat belts, narrow poly web, flat drive belts, small V belts (up to 1/8 inch, stationary), wide tape, and pallet-securing straps. It is the right choice within the Tensitron line for flat drive belts, wide tape, and label/web-type materials. If your exact material or width is not listed, Tensitron can advise on suitability.
Yes. The BTX-1 is purpose-built for flat drive belts and also handles small V belts up to 1/8 inch in a stationary measurement. For belt-drive maintenance and setup, this lets you verify tension is within target rather than relying on feel or deflection guesswork.
Yes. The BTX-1 is suited to wide tape and narrow poly web, which makes it applicable to tape, label, and web-handling lines where consistent web tension drives print registration, lamination, and converting quality. For specific tape or label web widths and materials, confirm the exact configuration with Tensitron.
The BTX-1 measures narrow, flat materials whether they are moving or stationary, so you can take readings on a running line as well as on stopped material. Note that the small V-belt rating (up to 1/8 inch) is specified for stationary measurement.
The BTX-1 measures tension ranges from 1 lb. to 500 lb. This span covers light web and tape applications at the low end through heavier straps and pallet-securing bands at the upper end.
Tension is specified in pounds (lb.), with the published range running from 1 lb. to 500 lb. If you require metric units (such as Newtons) or a different display configuration, confirm availability with Tensitron.

The BTX-1 delivers instant, accurate readings backed by onboard calibration data and a NIST-traceable calibration certificate supplied with the meter. The BTX-1 is accurate to ±2% of full scale, and accuracy may vary depending on the properties of the material measured. Scaling the meter to your expected tension levels improves accuracy at those levels. The meter also ships with an operating manual, available for download from the Tensitron software page.

Each BTX-1 includes a carrying case and a NIST-traceable calibration certificate, and custom rollers and calibrations are available for other materials and diameters. The display is a backlit digital readout with a color-bar graphic. The specific power source (battery type or charging method) is listed on the BTX Data Sheet.
The BTX-1 uses a three-roller measuring head: the flat material or belt is placed across the rollers so the meter deflects the band a known amount and converts that into a tension value, shown instantly on the backlit display. Built-in band selection and onboard calibration data let you select the correct material profile before reading, so results are consistent. For best results, follow the band-selection and measurement steps in the BTX manual.

What is a tension transducer and how is it different from a handheld tension meter?

A tension transducer is a sensor that is permanently mounted inline on a machine to continuously measure the tension of material as it runs through the process. Unlike a handheld meter, which a person uses to take spot checks by hand, a transducer converts tension into a reliable electrical signal that can be sent to a remote display, a high-speed recorder, or an automatic tension control system. This makes transducers ideal for continuous, measurable quality control and process traceability rather than periodic manual readings.
Tensitron mechanical tension transducer measuring wire tension
The ACM measures the static tension in a flexible cable — the pulling force carried along the cable, expressed in pounds (lb). It does this by deflecting the cable a known amount between three contact points and translating that deflection into a tension reading on the dial. This lets technicians confirm a control or structural cable is rigged within its correct tension range during installation, inspection, and routine maintenance.
The tension signal can be output for remote display, high-speed recording, or automatic tension control, giving you continuous, real-time tension data for process control and traceability. This lets you monitor a running process, capture data for quality records, and feed a control loop that holds tension to target. This applies to both the Fiber & Wire and Web & Belt lines.
The BTX-1 is ideal for narrow, flat materials including nylon straps, seat belts, narrow poly web, flat drive belts, small V belts (up to 1/8 inch, stationary), wide tape, and pallet-securing straps. It is the right choice within the Tensitron line for flat drive belts, wide tape, and label/web-type materials. If your exact material or width is not listed, Tensitron can advise on suitability.
Tensitron’s standard transducer offering spans from 1/10th gram up to 500 lbs across the catalog. Several fiber models (FT-107, FT-116, FT-117, E-415-002, F-1806) carry a listed range of 5 to 5,000 g. Higher-force models on the same page include single- and 3-roller low-force load cells (E-090-00, E-091-00) at 1 to 100 lb (up to 150 lbs noted on the single-roller E-090-00), and notched-beam transducers (E-095-01, E-095-03) at 10 to 1,000 lb. Many models can be customized to fit your exact range.
The Web & Belt line is designed for continuous tension measurement on wider, running materials and drive members, including webs such as textile, film, paper, tape, and label stock, and belts. Standard models include the E-415-003 Small Space Transducer with 3 rollers, the E-091-02 Low Force Cell with cylindrical rollers, the E-210-00 S-Column Transducer, the E-200-00 Cantilever Transducer, the 4260 Single Roller Web Transducer, the E-095-04 Notched Beam Transducer with cylindrical roller, and the E-202-00 Pillow Block Load Cell Transducer. Choose this line for permanently mounted, real-time quality control on web and belt processes.
Like the Fiber & Wire line, the standard transducer catalog ranges from 1/10th gram to 500 lbs. Listed typical ranges include the E-415-003 at 5 to 5,000 g, the E-200-00 Cantilever at 1 to 25 lb, the E-091-02 at 1 to 100 lb, the 4260 Single Roller at 2 to 200 lb, the E-210-00 S-Column at 5 to 250 lb, the E-095-04 (web applications) at 25 to 250 lb, and the E-202-00 Pillow Block at 25 to 1,000 lb. All transducers can be customized to meet your application requirements.
The BTX-1 measures tension ranges from 1 lb. to 500 lb. This span covers light web and tape applications at the low end through heavier straps and pallet-securing bands at the upper end.
Yes. Both lines are described as supporting automatic process control in addition to remote display and high-speed recording, and the sensors are characterized as precise, high-speed sensors permanently mounted for stable readings. That combination is what enables a continuous control loop. The specific controller, amplifier/conditioner, or PLC interface required for your setup should be confirmed with a Tensitron specialist.
The BTX-1 delivers instant, accurate readings backed by onboard calibration data and a NIST-traceable calibration certificate supplied with the meter. The BTX-1 is accurate to ±2% of full scale, and accuracy may vary depending on the properties of the material measured. Scaling the meter to your expected tension levels improves accuracy at those levels. The meter also ships with an operating manual, available for download from the Tensitron software page.
Both lines are permanently mounted (fixed) sensors. The transducer is installed inline so material runs across its roller(s), and it stays in place for stable, continuous readings. Models are offered in a variety of physical formats to suit the installation, including single-roller, 3-roller, low-profile/small-space, cantilever, S-column, notched-beam, and pillow-block configurations. The best mounting style depends on your machine geometry and available space. Each BTX-1 includes a carrying case and a NIST-traceable calibration certificate, and custom rollers and calibrations are available for other materials and diameters. The display is a backlit digital readout with a color-bar graphic. The specific power source (battery type or charging method) is listed on the BTX Data Sheet.
The BTX-1 uses a three-roller measuring head: the flat material or belt is placed across the rollers so the meter deflects the band a known amount and converts that into a tension value, shown instantly on the backlit display. Built-in band selection and onboard calibration data let you select the correct material profile before reading, so results are consistent. For best results, follow the band-selection and measurement steps in the BTX manual.
Choose the WX for wide, flat web and sheet materials — fabric, paper, film, foil, and conveyor belts — that you measure across their face with contact rollers. The BTX is oriented toward flat drive belts and wide tape. If your material is a continuous web or sheet rather than a discrete belt or tape, the WX is generally the better fit; for borderline cases, share your material width, type, and target tension with a Tensitron specialist.
The Memory Lock Pointer is a feature that holds the dial reading in place, which is especially useful when measuring in hard-to-reach areas where you can’t see the dial during the measurement. The calibration chart is attached directly to the meter so the reference you need to interpret the reading travels with the instrument. Each ACM also ships with a NIST-traceable calibration certificate.
The ACM is the mechanical/analog meter and the ACX is Tensitron’s digital meter; both are aimed at aircraft cables and other stationary cables up to 1/4″ in diameter. The ACM gives you no-power, no-battery analog reliability with a simple direct dial reading, while the ACX adds digital features. Choose the ACM when durability, simplicity, and battery-free operation matter most; choose the ACX when you want digital readout or data capabilities.

Why does my tension meter need to be recalibrated?

Tension meters are precision instruments, and normal handling, wear, and use can cause measurement drift over time, putting your readings out of tolerance. Recalibration verifies your meter still reads accurately against NIST-traceable standards and, at Tensitron, includes completely dismantling, cleaning, rebuilding, calibrating, and certifying the meter. This protects product quality, safety, and your own quality-system compliance, since out-of-spec tension can mean rejected parts, failed audits, or field failures.

Tensitron’s service is built around an annual calibration cycle, so a once-a-year recalibration is the standard recommendation for most users. If your meter sees heavy daily use, harsh environments, or supports critical aerospace or safety applications, you may want a shorter interval, while occasional-use meters may follow your own quality system’s schedule. When in doubt, contact us at (303) 702-1980 or service@tensitron.com to set the right interval for your application.
An overdue meter may have drifted out of tolerance without any visible sign, so you could be accepting or rejecting work based on inaccurate readings. In regulated environments such as aerospace, medical, and ISO 9001 or AS9100 quality systems, an expired calibration sticker can also trigger audit findings and force you to quarantine or re-inspect prior work. Sending the meter in on schedule is far cheaper than discovering a measurement problem after the fact.
The BTX-1 is ideal for narrow, flat materials including nylon straps, seat belts, narrow poly web, flat drive belts, small V belts (up to 1/8 inch, stationary), wide tape, and pallet-securing straps. It is the right choice within the Tensitron line for flat drive belts, wide tape, and label/web-type materials. If your exact material or width is not listed, Tensitron can advise on suitability.
Yes. All Tensitron calibrations are NIST-traceable and performed according to established, documented procedures using standards that are fully traceable directly to NIST. The calibration weights used range from zero to 4,000 pounds and are certified by a third party every five years, and the cables used are inspected at least annually against MIL-DTL-83420N, Table 1, with measuring equipment checked against traceable standards every 12 months. This unbroken traceability chain is what makes your readings defensible in audits and with customers.
The Web & Belt line is designed for continuous tension measurement on wider, running materials and drive members, including webs such as textile, film, paper, tape, and label stock, and belts. Standard models include the E-415-003 Small Space Transducer with 3 rollers, the E-091-02 Low Force Cell with cylindrical rollers, the E-210-00 S-Column Transducer, the E-200-00 Cantilever Transducer, the 4260 Single Roller Web Transducer, the E-095-04 Notched Beam Transducer with cylindrical roller, and the E-202-00 Pillow Block Load Cell Transducer. Choose this line for permanently mounted, real-time quality control on web and belt processes.
Like the Fiber & Wire line, the standard transducer catalog ranges from 1/10th gram to 500 lbs. Listed typical ranges include the E-415-003 at 5 to 5,000 g, the E-200-00 Cantilever at 1 to 25 lb, the E-091-02 at 1 to 100 lb, the 4260 Single Roller at 2 to 200 lb, the E-210-00 S-Column at 5 to 250 lb, the E-095-04 (web applications) at 25 to 250 lb, and the E-202-00 Pillow Block at 25 to 1,000 lb.

There are three simple steps: complete the online service form on the Calibration & Service page, package your meter securely, and ship it to Tensitron at 135 Industry Drive, Pittsburgh, PA 15275. No RMA number is required. Be sure to include your contact and return-shipping details so the service team can reach you with the estimate.
No. Tensitron does not require an RMA number. Simply complete the online service form, then package and ship your meter to 135 Industry Drive, Pittsburgh, PA 15275. Including a printed copy of your submitted form, or a note with your company, contact, and meter details, helps the team match your meter to your request quickly.
The BTX-1 delivers instant, accurate readings backed by onboard calibration data and a NIST-traceable calibration certificate supplied with the meter. The BTX-1 is accurate to ±2% of full scale, and accuracy may vary depending on the properties of the material measured. Scaling the meter to your expected tension levels improves accuracy at those levels. The meter also ships with an operating manual, available for download from the Tensitron software page.
Tensitron highlights fast turnaround as a core reason to use the factory service; standard turnaround is typically within two weeks, and expedited service is available upon request for an additional fee. Note that a meter is only worked on after approval (a purchase order or payment) is received, so responding promptly to your estimate keeps the timeline short.
Choose the WX for wide, flat web and sheet materials — fabric, paper, film, foil, and conveyor belts — that you measure across their face with contact rollers. The BTX is oriented toward flat drive belts and wide tape. If your material is a continuous web or sheet rather than a discrete belt or tape, the WX is generally the better fit; for borderline cases, share your material width, type, and target tension with a Tensitron specialist.
If you send a meter in and then choose not to proceed with the required service, a $100 Evaluation Fee is assessed, and the Evaluation Fee and return shipping must be paid before the meter ships back. A Storage Fee of $25 applies if a meter remains more than 30 days from the date of estimate to the date approval (a purchase order or payment) is received, plus $10 for each subsequent week, partial or full. A meter is considered abandoned and will be discarded if no communication is received within six months of the customer receiving the estimate.
Recalibration verifies and certifies accuracy, while repair restores a meter that is damaged or out of tolerance. Tensitron’s standard service already bundles a thorough overhaul: dismantling, cleaning, rebuilding, calibrating, and certifying, so many issues are corrected as part of the normal service. If an out-of-tolerance meter needs additional parts or repair beyond the standard service, you will be notified of any added charges before the work proceeds.
As the original manufacturer, Tensitron performs detailed inspection, evaluation, testing, repair, and calibration on Tensitron instruments returned for service, and maintains history logs of the instruments it has calibrated and sold. The safest path is to submit the service form or call (303) 702-1980 with your model and serial number so the team can confirm support before you ship.
Calibration and service are performed in-house at Tensitron’s Pittsburgh, PA facility by the instrument makers who build the meters, which is what backs the ISO/IEC 17025-certified, NIST-traceable certificate.
