This kind of displacement sensor in life, also known as linear displacement sensor, is a kind of linear electronic parts induced by metal. The purpose of the sensor is to convert a variety of measured physical quantities into electricity. In the process of consumption, the measurement of displacement is generally divided into physical measurement and mechanical displacement. According to the different ways of transformation, the displacement sensor can be divided into two types: imitation and digital. Imitation can be divided into physical type and structural type, and most of the commonly used displacement sensors are imitated structures. it includes potentiometer displacement sensor, inductive displacement sensor, synchro, capacitive displacement sensor, eddy current displacement sensor, Hall displacement sensor and so on. The digital displacement sensor has an obvious advantage that it can transmit the signal directly to the computer system very quickly. This kind of sensor develops rapidly and its application is becoming more and more common.
