The photoelectric displacement sensor measures the displacement or the geometric dimension of an object according to the amount of light flux blocked by the object to be measured, belongs to non-contact measurement and can carry out continuous measurement. Photoelectric displacement sensors are commonly used for continuous measurement of wire diameter or as edge position sensors in strip edge position control systems. The photoelectric displacement sensor is based on a photoelectric effect sensor, generates a photoelectric effect after being irradiated by visible light, and converts an optical signal into an electric signal to be output. It can measure various physical quantities, such as size, displacement and speed, by using the transmission, shielding, reflection and interference of light, so that it is an important sensitive device with extensive application. The photoelectric measurement is not in direct contact with the measured object, the quality of the light beam is approximate to zero, and no friction exists in the measurement and almost no pressure is applied to the measured object. Therefore, in many applications, photoelectric sensors have significant advantages over other sensors.
