introduction：Displacement sensorAlso known as linear sensor，It is a linear device belonging to metal induction，The function of the sensor is to convert various measured physical quantities into electricity。In the production process，The measurement of displacement is generally divided into two kinds: measuring physical size and mechanical displacement。The form of transformation varies according to the variable under test，Displacement sensors can be divided into analog and digital two types。Simulation can be divided into two types: physical type and structural type。Most of the commonly used displacement sensors are analog structures，Includes a potentiometer type displacement sensor、Inductive displacement sensor、Synchro machine、Capacitive displacement sensor、Eddy current displacement sensor、Hall displacement sensor, etc。An important advantage of digital displacement sensors is the ease of sending signals directly into the computer system。The sensors are developing rapidly，Increasingly widely used。
