Torque sensor has gone through three stages

Torque sensor development has come a torque sensor development has gone a long time, the torque sensor performance is getting better , in fact, torque sensors can be divided into three stages, namely measurement technology generation, the first rotation torque sensors birth and modern torque sensor .The historical evolution of torque measurement technology , beginning in 1678 . In that year, Robert Hooke Hooke's law describes the well-known materials and related materials extending proportional relationship between tension . Bridge circuit , and the Hunter- Christie , the smallest change in voltage can be measured . However, the name of the inventor to switch second Wheatstone , the actual fame belongs Heng Teke view .The first rotary torque sensors and Positioning Sensor measurement system in 1945 on the market it is based on the principle that if the bottom of the axial load torque , reversing an angle proportional to the torque . This angle measuring system can measure the angle .Modern torque sensors typically have an analog signal output. In these interfaces , the power module and the adjacent interference drive is possible, especially in the case in the past for the long feed lines and high dynamic , increasing the level of the sensor signal , the signal level of ± 5V and / or typically ± 10V.However, in many applications, anti-interference ability is not enough. The solution is a digital electronic sensors . Modern torque Crankshaft Sensor Replacement, integrated electronics in the area of ​​the shaft , the above diameter reduction , is applied to the rotating part of the rotary transformer and the axis of rotation electron attachment .Torque sensor technology is still rapidly developing , believe that with the development of sensor technology , the torque sensor performance will also be further improved. Will further expand its scope of application .
