拧紧轴扭矩传感器的功能是产生一个动态的电子信号，用来反映施加在螺栓头部的扭矩。这可以通过测量输出轴上的反作用力造成的机械扭转来实现。春龙拧紧机采用德国试达默原装进口扭矩传感器，也可根据客户要求选用其它品牌扭矩传感器。

Torque sensor is to give a dynamic electronic signal, reflecting the torque imposed on bolt head part. This can be done by testing mechanical torque generated by counter-force of output shaft. Chunlong Tightening Machine adopts original Staiger Mohilo torque sensor imported from German. Other brand is also available as per customer requirements.
