What makes our torque meters stand out? Experience.

At ATESTEO, torque measurement is more than a component. It’s a core part of our testing philosophy. That’s why we’ve spent decades refining our sensor designs to meet the real-world demands of drivetrain development.

Our torque transducers are built by engineers who understand drivetrain behavior, not just sensor specs.

The result: sensors that perform where others fail.

Backed by US expertise.

All ATESTEO torque meters are developed and manufactured in Germany — with the precision and quality that modern drivetrain testing demands. But precision doesn’t end with delivery. Our US-based experts support you with integration advice, calibration checks, and configuration help to ensure smooth operation on your test bench.

Wherever you test torque, we’ve got your back.

Still have questions? Let’s clear a few up.

Here are some of the most common questions we get from drivetrain engineers when it comes to torque sensors.

Lead times vary depending on sensor type and interface requirements. Standard models are often available within 4-5 weeks. Custom configurations may take longer. We’ll clarify timelines up front.

Yes. Most ATESTEO sensors offer multiple interface options including CAN, frequency (RS422) and analog voltage. We’ll match your measurement system.

That’s what we’re here for. Our engineers support mechanical fit, telemetry setup, cabling, and signal compatibility to ensure fast and reliable integration.

Most of our ATESTEO torque meters can be manufactured with customized nominal (rated) torque ranges. Because accuracy is relative to the nominal torque, this can improve accuracy in the system. However, it is possible that items with customized nominal torque ranges may result in increased costs or longer delivery times. Please contact us. We would be delighted to assist you.

A torque meter receives two sensitivity values after it has been calibrated. The sensitivity value is used to convert the raw measured value into a torque measured value. Therefore, the sensitivity value has the unit “Hz/Nm” or “digits/Nm”. One of the two sensitivitiy values converts the measured value of a positive loading direction (clockwise) into a torque value; the other sensitivity value converts the measured value of a negative loading direction (counterclockwise) into a torque value. To achieve maximum accuracy, both sensitivity values must be stored in the data recording system (measuring system or control system). If the data recording system only allows the input of one value, an averaged slope value can be calculated (with slight decreases in accuracy).

For planning a facility, ATESTEO provides design data on its torque meters. The data are dimensional drawings or 3D models (e.g., STEP files). Many torque sensors can be found around the clock on Traceparts.com. Dimensional drawings and 3D models can be downloaded from there. In any case, you can also request data directly from us. Just send us a request via email (equipment@atesteo.com)

Every ATESTEO torque meter can send various status messages, such as error messages or alarms. This occurs, for example, through digital outputs or a detailed status word on the CAN bus. These signals permit the system to automatically monitor the status of the torque meter. If errors or problems occur, deeper analyses can be performed using the configuration software.

In a torque measuring shaft (torque meter), torque causes the measuring body to twist; this twisting is initially measured with the aid of strain gauges. The strain gauges theoretically provide an infinite number of measured values per second. This raw signal is converted into a digital signal (frequency, data word) by electronic components. The conversion is achieved by internal high-frequency sampling. The outgoing measurement signal is now discrete in time and provides a limited number of measured values per second. The dynamics of a torque meter define the maximum frequency that can be measured with the measuring signal via signal analysis.

Torque meters are usually calibrated without a measuring system/data recording. This is why testing the measuring chain after receiving the torque sensor is a good idea. Torque meters from ATESTEO offer the function of a test signal for this purpose. This signal can be activated via the configuration software. When the test signal is active, the sensor does not output a measurement value, but rather, a precisely defined signal. The definition of the signal can be found in the test report. The end of the measuring chain should be compared to this reference value.
