Position sensor
From Wikipedia, the free encyclopedia
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
