“…In practice, more data is required to achieve higher accuracy through filtering. The principle of operation of the sensor [18] is based on measuring the amount of rotation of the rotating shaft when a torque is given to it. According to the method of reading the amount of rotation of the shaft, they are divided into two types: -measurement of voltage -measurement of pulse In the strainometric method, strain gauges are attached to the torsion shaft, the signal from it is amplified, converted into a serial digital code and transmitted to an external measuring device using a non-contact rotary transformer.…”

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