Displacement Sensor
Aug 08, 2018

Displacement sensors, also known as linear sensors, convert sensors into electrical quantities. The displacement sensor is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electric quantity. It is divided into inductive displacement sensor, capacitive displacement sensor, photoelectric displacement sensor, ultrasonic displacement sensor, Hall. Displacement sensor.

There are many physical quantities (such as pressure, flow, acceleration, etc.) in this conversion process that often need to be transformed into displacements before they are converted into electricity. Therefore, displacement sensors are an important class of basic sensors. In the production process, the measurement of displacement is generally divided into two types: physical size measurement and mechanical displacement. Mechanical displacement includes line displacement and angular displacement. Depending on the form of the measured variable, the displacement sensor can be divided into analog and digital. The analog type can be divided into two types: physical type (such as self-generating type) and structural type. Commonly used displacement sensors are mostly analog type structures, including potentiometer type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, and the like. An important advantage of digital displacement sensors is the ease with which signals can be sent directly to a computer system. Such sensors are developing rapidly and are becoming more widely used.
