Torque measurement

Torque measurement allows OEMs to monitor rotational forces in motors, gearboxes, and drive systems to ensure efficiency and early fault detection.

Strain gauge torque sensors are widely used for their high accuracy, long-term stability, and ability to convert torsional deformation into precise electrical signals. For highly dynamic applications, piezoelectric torque sensors provide fast response and robust operation.

A custom torque sensor design enables direct integration into OEM systems while delivering reliable, high-resolution data throughout the product lifecycle.
