Position sensor

Position sensor

A position sensor is any device that enables position measurement. It can either be an absolute position sensor or a relative one (displacement sensor). Position sensors can be either linear or angular.

Some position sensors available today:-

* Inductive Non-Contact Position Sensors
*String Potentiometer (aka String Pot)
*Linear variable differential transformer (LVDT)
*Potentiometer
*Capacitive transducer
*Eddy-current sensors
*Hall effect sensor
*Proximity sensor(optical)
*Grating sensor
*Encoding disc (angular)
*Seismic displacement pick-up
*Piezo-electric transducer
*Photodiode array
