Application of photoelectric sensor in speed measurement system

With the rapid development of mechanical automation, rotational speed is an important characteristic parameter in dynamic mechanical performance testing.

Many characteristic parameters of power machinery are often determined by the speed, such as the output power of the motor, the vibration of the power machinery, the gas pulsation of the pipeline, and the wear status of various working parts are also closely related to the speed. Timely monitoring of changes in machine speed can eliminate many faults in machine operation in time and avoid greater losses. According to the installation method of the photoelectric sensor, the speed measurement method is divided into contact type and non-contact type.

Non-contact rotational speed measurement sub-plate magnetic measurement, axial magnetic measurement, barrier photoelectric measurement and reflective photoelectric measurement. The photoelectric speed measurement system has the advantages of non-contact, fast response, reliable performance, high precision, high resolution, etc., and has been widely used in the field of measurement and control
