Displacement Sensors

Displacement sensors measure the position or distance of an object. They can also be used to measure object’s height and width. There are 2 types of displacement sensors: Contact displacement sensors, utilizing a dial gage, differential transformer, etc., and non-contact displacement sensors, utilizing a magnetic field, Inductive /eddy current , laser beam, ultra-sonic wave, etc.
