A displacement sensor is a device commonly used to measure the displacement of an object. Displacement sensors can be divided into the following types according to their working methods.


位移传感器


The first is the classification according to the movement mode. A linear displacement sensor is a sensor that detects displacement changes by measuring the displacement of an object in a linear direction. The angular displacement sensor is mainly used to measure the displacement change of an object rotating around a certain center point, such as the angle change of a robotic arm.



The second is based on material classification. Metal film sensors, conductive plastic sensors, photoelectric sensors, magnetic sensors, metallic glass uranium sensors and wire-wound sensors are all common displacement sensor materials. Sensors made of different materials have different characteristics and application ranges, and users can choose the appropriate material according to actual needs.



The third is based on the classification of contact methods. Contact displacement sensors mainly include magnetostrictive displacement sensors, pull cord displacement sensors, grating displacement sensors and inductive displacement sensors. These sensors need to be in direct contact with the object being measured and output signals by measuring its displacement.



Non-contact displacement sensors do not require direct contact with the object being measured. Eddy current displacement sensors, laser displacement sensors and ultrasonic displacement sensors are all common non-contact displacement sensors. These sensors can measure the displacement of the object being measured without touching it, and are particularly suitable for situations where there are certain requirements on the surface of the object being measured.



To sum up, displacement sensors can be divided into many types according to different classification methods, and each type of sensor has different characteristics and scope of application. When selecting a displacement sensor, users can choose the appropriate sensor type based on actual needs and application scenarios. Whether it is a linear displacement sensor or an angular displacement sensor, whether it is a metal film sensor or a laser displacement sensor, choosing the displacement sensor that suits you is crucial to achieving accurate measurement and control.
