Detailed classification of displacement sensors, detailed understanding of displacement sensors
Release date: June 1, 2019
Displacement sensor is also known as linear sensor, which converts displacement into electricity. Displacement sensor is a kind of linear device which belongs to metal induction. The function of sensor is to convert all kinds of measured physical quantities into electric quantity. It is divided into inductive displacement sensor, capacitive displacement sensor, photoelectric displacement sensor, ultrasonic displacement sensor and Hall displacement sensor.
In this conversion process, there are many physical quantities (such as pressure, flow rate, acceleration, etc.) which need to be transformed into displacement first, and then into electric quantity. Therefore, displacement sensor is an important class
Basic sensors. In the process of consumption, the measurement of displacement is generally divided into physical measurement and mechanical displacement. Mechanical displacement includes linear displacement and angular displacement. The displacement sensors can be divided into two types: analog and digital according to the different ways of transformation. Imitation can be divided into physical type (such as self generating type) and structural type. The most commonly used displacement sensors are analog type, including potentiometer type
Displacement sensor, inductive displacement sensor, synchro, capacitive displacement sensor, eddy current displacement sensor, Hall displacement sensor, etc. An important advantage of digital displacement sensor is that it is easy to send the signal into computer system directly. This kind of sensor develops rapidly, and its application is more and more common.
