Multi-Axis Torque Sensors
Multi-axis torque sensors (multi-component transducers) are ideal when you need to measure torque and force(s) simultaneously—for example, force and torque along the same axis. Thanks to minimal cross-talk between measurement channels, they provide direct, clean measurement data without the need for complex mathematical corrections or computational deviations.
They are particularly suitable for testing and development tasks where multiple load parameters act simultaneously and must be evaluated separately. Depending on the design, axial forces and reaction torques can be measured independently. The channels can also be calibrated bidirectionally, ensuring reproducible results in testing environments.

Answers to the most important technical Questions
What measuring ranges are available for multi-axis torque sensors?
The measuring ranges of multi-axis torque sensors depend on the specific design and axis combination. For the ATF310 series, the standard measuring range is 50 N axial force and 2 Nm torque. Because multi-axis sensors are often designed for specific applications, custom measuring ranges are also possible. This applies both to the combination of force and moment axes and to the rated ranges of the individual channels. Many ATF310 versions are manufactured to specific requirements and calibrated accordingly. When selecting a sensor, the required force and torque range, loading direction, overload reserve, accuracy, crosstalk between channels, installation space, mechanical interfaces and evaluation electronics should all be considered. Althen can support the design of a suitable multi-component transducer for the specific test-bench, development or process application.
Which force and torque axes can multi-axis torque sensors measure?
Depending on the design, multi-axis torque sensors can measure forces and moments in several directions. In the ATF310 series, an axial force and a reaction torque are measured along the same axis. This makes it possible, for example, to measure tensile and compression forces along the sensor axis as well as the torque acting around that axis. The mechanical quantities are converted directly into electrical signals using separate full-bridge strain-gauge systems. This enables direct measurement with minimal crosstalk between the force and torque channels, without requiring complex mathematical decoupling of the measured values. Each measurement channel can be calibrated bidirectionally, allowing measurements in both loading directions. For applications requiring additional axes or custom measuring ranges, Althen offers adapted sensor designs and complete measurement solutions in addition to standard torque sensors. The exact axes that can be measured therefore depend on the selected sensor design, measuring range, calibration and mechanical integration.
