The speed sensor is mainly a kind of sensor that can convert the rotational speed of a rotating object into electric quantity for output. It is an indirect measuring device. Generally uses the mechanism, electric, magnetism. It can be applied in some workpiece machining speed monitoring. It can monitor the workpiece speed on the CNC machine in real time, which is helpful for more precise machining and operation of the workpiece. The problem that the speed sensor should pay attention to when using it is
1. The speed sensor should ensure that the gap between the bottom of the sensor and the tooth tip of the engine is within a certain range, generally between 0.8 and 1.0 mm. If the gap is not within this range, then the indication may not be caused. Accurate, affecting
2. The correct installation method when using the speed sensor should firstly screw the sensor to the bottom so that the bottom of the sensor touches the top position of the engine flywheel teeth, then counterclockwise to rotate 2/3 turns, and finally use the back nut. It’s ok to fasten the sensor
3. When the speed sensor is idling, ensure that the output induced voltage value of the speed sensor is in the range of Urms>1.0V.
