Mechanical traction dynamometer TX
The TX mechanical force gauges
The TX mechanical dynamometer is a compact and rugged instrument for measuring tensile forces, designed for heavy-duty use in industrial environments. It works on the principle of the elastic deformation of a spring housed in a steel casing, without any delicate electronic components. Its design makes it completely impervious to temperature fluctuations and adverse weather conditions, allowing it to be used in laboratories, on production sites, or outdoors.
A built-in safety stop prevents damage in the event of accidental overload, and the maximum release index allows the peak value to be retained after the test without maintaining the load. The TX series covers ranges from 60 to 600 daN (approximately 61 to 612 kg), with an accuracy of ±4% and a usable reading starting at 1/10 of the full scale.

🔸A device that requires no power source and has no usage limits
The TX requires no battery, no power supply, and no software. It is ready to use immediately, with no warm-up time or prior setup required. There is no limit on the number of tests or the duration of testing. This solution is particularly well-suited for production control stations where uptime and ease of use are top priorities.
🔸The maximum disengageable index
The maximum index is a pointer that moves along the scale during the test and remains in position after the force is released. It allows you to read the maximum value reached without maintaining traction, which makes it easier to take measurements in situations where access to the scale is difficult during the test.
🔸A safety factor of 5
The TX structure is designed to withstand five times its rated capacity without permanent deformation. This high coefficient ensures the instrument’s durability even in the event of improper use or accidental impact, and contributes to the operator’s safety.
🔸Comes with an ACRN calibration certificate
Each TX dynamometer comes with a calibration certificate issued by ACRN. We recommend an annual preventive calibration check, which can be performed on-site or at our metrology laboratory in Normandy.

Applications and Industries
The TX mechanical dynamometer is used in many industrial sectors for quality control and force verification applications:
🔸Manufacturing and Assembly
Measurement of pull-off force and tensile strength of welds, adhesive bonds, or mechanical fasteners on production lines or in design offices.
🔸Packaging and Packaging Materials
measuring the force required to open packaging, testing the mechanical strength of closures, and verifying crimping or clipping forces.
🔸Construction and Lifting
Verification of tension forces on cables, straps, or anchoring systems, using the sturdy lifting eyes integrated into the housing.
🔸Maintenance and Field Operations
Thanks to its lack of a power supply and its weather resistance, the TX is ideal for inspections in harsh environments or outdoors.
🔸Calibration and Metrology
used as a transfer standard in metrology laboratories for the verification of other force measurement instruments.
Best practices for measurement
To ensure accurate results, make sure the dynamometer is perfectly aligned with the pull axis before applying force. Use appropriate shackles in the lifting eyes—never apply force off-axis. Wait until the reading has completely stabilized before taking the measurement. Stand facing the graduated scale to avoid parallax errors.
The valid reading begins at 1/10 of the measurement range: for a TX 100, the measurement is reliable starting at 10 daN. Below this value, the measurement uncertainty is too high to guarantee the stated accuracy of ±4%.
Why choose a mechanical dynamometer over an electronic one?
The TX mechanical dynamometer is particularly well-suited for situations where simplicity and durability take precedence over connectivity. Unlike electronic force gauges, it requires no batteries or electronic maintenance and operates under extreme temperature or humidity conditions. It is the preferred choice for field control stations, ATEX environments, or simply for users who want a reliable, cost-effective tool that isn’t tied to any specific technology. Its annual calibration by ACRN ensures the metrological traceability required by ISO 9001 quality management systems.
