What is a Displacement sensor?

A displacement sensor is a device used to accurately measure the position or movement of an object. There are two main types: contact and non-contact sensors. Contact types include potentiometers and LVDTs (Linear Variable Differential Transformers). Non-contact types include capacitive sensors, laser displacement sensors, eddy current sensors, and ultrasonic sensors. These sensors are used in various fields such as industrial machinery position control, product quality inspection, automotive engine part measurement, and structural deformation monitoring in buildings. Displacement sensors play a crucial role in environments where precise measurements are required, and advancements in technology continue to enhance their accuracy.

Application of Displacement sensor

A displacement sensor is a device used to measure the position or displacement of an object. There are mainly the following types:

１．Contact Displacement Sensors
　　Potentiometers: Sensors that change resistance through physical contact.
　　LVDTs (Linear Variable Differential Transformers): High-precision sensors that use magnetic induction.

２．Non-Contact Displacement Sensors
　　Capacitive Sensors: Sensors that measure changes in capacitance between electrodes.
　　Laser Displacement Sensors: Sensors that measure distance using lasers.
　　Eddy Current Sensors: Sensors that measure displacement on the surface of metals.
　　Ultrasonic Sensors: Sensors that determine distance by measuring the reflection time of ultrasonic waves.

These sensors are used in various fields such as position control of industrial machinery, product quality inspection, measurement of automotive engine parts, and monitoring of structural deformations in buildings.
