Research on non-contract torque measurement for solenoid-type differential transformer

Torque measurement is one of the important items for the conveying line.The non-contract torque measurement method with high precision and high stability is one of the research hotspots for mechanical quantity measurement in the world today.Therefore,a non-contract torque sensor for solenoid-type differential transformer is proposed.This paper introduces the principle of this measurement method and its structure.The loading test for the developed sensor was carried out,and the fitting equation was obtained from the experiment data.The experiment results show that the measurement principle is feasible,the designed torque sensor has better linearity and consistency,the repeat precision of the sensor is less than or equal to 0.5%.
