Displacement sensor definition
Displacement sensor, also known as linear sensor, 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 types: physical size measurement and mechanical displacement. According to the form of the measured variable transformation, the displacement sensor can be divided into analog and digital. The analog type can be divided into two types: physical type and structural type. Commonly used displacement sensors are mostly analog type structures, including potentiometer displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, and Hall-type displacement sensors. An important advantage of digital displacement sensors is the ease with which signals can be sent directly to a computer system. Such sensors are rapidly evolving and are becoming more widely used.
