FAQ

Our magnetoelastic sensors capture torque with no mechanical contact to the shaft. The ferromagnetic shaft is permanently magnetised and so becomes the sensor itself. That reduces maintenance and wear to nothing.

They allow machine condition to be monitored continuously. Slow changes in the torque curve show up early. Failures can be spotted before they bring things to a halt.

Yes. Our torque flanges integrate flexibly and are adapted to your requirements, as original equipment and as a retrofit to what is already installed.

We stay with you from concept development through prototype manufacture to installation and commissioning, including FEM analysis of your shaft and signal conditioning designed for the case.

The method works on selected ferromagnetic steels. In some cases the shaft needs a defined heat treatment. Near-field telemetry, by contrast, can be applied to any material, steel, carbon and aluminium among them.

Measurement is possible from 0.01 Nm to several thousand Nm. Since no additional components go onto the shaft itself, speeds up to 300,000 rpm are within reach.

Typical measuring accuracy is between 0.05 and 1 % FS. Signal bandwidth is typically 1 to 2 kHz and can be raised above 25 kHz for customer-specific applications.

Yes. We calibrate torque sensors up to 10,000 Nm in our own laboratory, our own and other makes alike. We also offer temperature calibration for Young’s modulus compensation.
