Linear position sensot also known as linear displacement sensor or electronic ruler. It is divided into inductive displacement sensor, capacitive displacement sensor, photoelectric displacement sensor, ultrasonic displacement sensor, Houle displacement sensor.

workpriciple of linear position sensor

The displacement sensor is a linear metal sensing device. When the power supply is switched on, an alternating magnetic field will be generated on the sensing surface of the switch, the Eddy current in the metal absorbs the energy of the Oscillator, attenuates the amplitude of the Oscillator linearly, and then detects the object without contact according to the change of the attenuator.

The displacement sensor has no sliding contact, is not affected by dust and other non-metallic factors, and low power consumption, long life, can be used in a variety of harsh conditions. The displacement sensor is mainly used in the intelligent control of the analog quantity in the automatic equipment production line.
