In many servo-applied systems, a large number of sensors are needed, of which angle sensors have a very large number of applications in the textile industry.
An angle sensor, as the name suggests, is a device that converts an angle value into a voltage or current signal. At present, a contact type rotary potentiometer is adopted. The angle sensor may be used in a textile apparatus to detect the tension of the yarn.
The contact type rotary potentiometer internally adopts a circle of carbon brush, along with the change of the angle of the knob, the position of the electric shock on the round carbon brush changes along with the angle, so that the resistance value of the electric shock and the 0V potential point changes along with the change, and after a power supply is connected, the voltages at two ends of the resistor also change along with the change, so that the linear relation between the voltage and the angle of the knob is realized, and the function of an angle sensor is realized. However, the contact rotary potentiometer has the defects of wear resistance, oil resistance, water resistance, dust resistance and moisture resistance, so that the service life is short and the precision is low. The existing non-contact angle sensor adopts a Hall element for detection, and the whole cost of the Hall element is higher.
