Position sensor
Appearance
Aposition sensoris asensorthat detects an object's position. A position sensor may indicate the absolute position of the object (its location) or its relative position (displacement) in terms of linear travel, rotational angle or three-dimensional space. Common types of position sensors include the following:
- Capacitive displacement sensor
- Eddy-current sensor
- Hall effect sensor
- Inductive sensor
- Laser Doppler vibrometer(optical)
- Linear variable differential transformer(LVDT)
- Photodiode array
- Piezo-electric transducer(piezo-electric)
- Position encoders:
- Potentiometer
- Proximity sensor(optical)
- String potentiometer(also known as astring potentiometer,string encoderorcable position transducer)
- Ultrasonic sensor
