What Is A Displacement Sensor?

Displacement sensor, also known as linear sensor, is a sensor that converts displacement into electrical quantity. Displacement sensor is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electrical quantities. It is divided into inductive displacement sensor, capacitive displacement sensor, photoelectric displacement sensor, ultrasonic displacement sensor, Hall displacement sensor.
In this conversion process, many physical quantities (such as pressure, flow, acceleration, etc.) often need to be converted into displacement first, and then the displacement is converted into electrical quantity. Therefore, displacement sensor is an important basic sensor. In the production process, displacement measurement is generally divided into two types: measuring physical size and mechanical displacement. Mechanical displacement includes linear displacement and angular displacement. According to the different forms of measured variable transformation, displacement sensors can be divided into analog and digital types. Analog type can be divided into physical type (such as self-generating type) and structural type. Commonly used displacement sensors are mostly analog structural types, including potentiometer displacement sensor, inductive displacement sensor, self-synchronous machine, 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 signals directly into computer systems. This type of sensor is developing rapidly and its application is becoming more and more extensive.
Pressure
Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electricity, ships, machine tools, pipelines and many other industries.
