Magnetic Elastomer Sensor for Dynamic Torque and Speed Measurements

In this paper is proposed a dynamic torque, rotational speed, and shaft position sensor. It built of magnetic elastomer coating directly applied over rotating shaft. The sensor used for precise measurements changes in torque it usable at high speeds, on the device based material deformation corresponding change field amplitude direction. design simple can acquire reliable readings wide range speeds. Sensor consists following: with nanoparticles, which, sensing convertor; magneto-resistive linear sensor; microprocessor unit calibration control. Numerical experimental test results are demonstrated analyzed. implementation aims to meet mechatronic systems’ specific requirements.
