What is the function of a torque sensor?

[OAbel]

Torque sensor is used to measure the torque transmitted between the steering wheel and the steering gear output shaft, and convert the torque value into a voltage signal sent to the ECU. The torque sensor is a crucial determining factor in adjusting the steering assist force, and the quality of its output signal will simultaneously affect the vehicle's handling safety, especially during high-speed driving. Torque sensors are also known as torque transducers, moment sensors, torsion sensors, or torque meters, and are divided into two main categories: dynamic and static. Torque sensors can be applied in the manufacturing of viscometers, electric, pneumatic, and hydraulic torque wrenches, offering advantages such as high precision, fast frequency response, good reliability, and long service life.
