Rotary Torque Sensor: Precision Measurement for Automotive and Industrial Applications


When measuring torque, which is the rotating force imparted to an item, a rotary torque sensor is an essential tool. Torque measurement is critical to a variety of applications, ranging from automobile engineering to industrial gear. The interesting world of rotary torque sensors, including their uses, advantages, installation concerns, maintenance advice, potential future trends, and more, will be examined in this article.


Utilizing strain gauges or the magnetoelastic effect, rotary torque sensors work. Torque causes a change in electrical resistance, which strain gauge-based sensors use to measure torque. By quantifying and converting this change, torque data is produced.

Magnetoelastic sensors, on the other hand, employ the variation in magnetic characteristics brought on by torque to ascertain the applied force.

Rotary torque sensors come in a variety of designs, including optical, piezoelectric, and magnetostrictive ones. When a piezoelectric sensor detects mechanical stress, an electrical charge is generated, but the light is used when an optical sensor detects torque. Magnetostrictive sensors use the magnetic characteristics of materials to precisely measure torque.
