First is the inductive torque sensor: this type of sensor is mainly used in a non-contact measurement method, this torque sensor has a longer life, high reliability, and is not easy to be subjected to wear and tear. Second is the potentiometer type torque sensor: this type of sensor according to the type can be divided into gear type, torsion bar type, rotary arm type. The torsion bar type measurement structure is simple, relatively high reliability, in the early application of more. This type of sensor are contact type, there is wear and tear, reducing its performance.
There is a metal resistance strain gauge type: this type of torque sensor is mainly in the elastic shaft paste strain gauges to form a measurement bridge, and when the elastic shaft by the torque, it will produce a small deformation after the bridge resistance caused by changes in the resistance of the strain bridge changes into the voltage signal changes to achieve the torque measurement we want. However, this type of torque sensor is affected by the strain gauge material and the accuracy of the voltage regulator.
