Torque sensors are widely used in the field of industrial machinery, they are an important guarantee for the control accuracy of material torsion test equipment. The working environment of torque sensor application site is complex, which is often different from that of calibration in the laboratory. Based on its measurement principle, the metering performance of torque sensor will be different under different Temperature conditions. In this paper, the performance differences of common strain torque sensors under different environmental conditions are analyzed, and the temperature performance evaluation method are introduced. The structure and performance of torque standard machine and thermal insulation coupling which can be used for temperature test, as well as a series of calibration tests and results carried out by using this device.
