Torque sensor technology is becoming more and more mature, but its development has gone through three stages:

The first stage is the generation of measurement technology. In 1678, Robert Hooke described Hooke’s Law, the proportional relationship between the elongation of a material and the tension of the material in question. Moreover, the bridge circuit made it possible to measure small changes in voltage.

The second stage rotary torque sensor is born. In 1945, a platform rotary torque sensor was introduced on the market, based on the principle that if the axial torque of the loaded shaft below is twisted by an Angle, the torque will also change proportionally. The Angle of this twist can be measured by a measuring system.

Third stage modern torque sensor. Modern torque sensors generally have analog output, in these interfaces, adjacent drivers may produce interference, and then the appearance of digital electronic sensors to enhance anti-interference capabilities.

So far, torque sensors are still evolving rapidly, with more variety and capabilities. Its testing system will also develop towards miniaturization, digitalization, intelligence, virtualization and networking, from static testing to dynamic online testing direction.
