Position sensor
A position sensor is any device that permits 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 sensor
- Hall effect sensor
- Laser Doppler Vibrometer
- Proximity sensor (optical)
- Grating sensor
- Rotary encoder (angular)
- Seismic displacement pick-up
- Piezo-electric transducer(Piezo-electric)
- Photodiode array
