Principle of Operation of Magnetostrictive Position Sensors
Magnetostrictive sensors detect the location of a magnetic ring that slides along a conductive metal tube; in other words this sensor operation utilizes the effect of a magnetic field on magnetostrictive wire to function. The figure below illustrates a Magnetostrictive … Read more
The Principle of Operation of Optical Encoders
An encoder is a device that provides a digital output as a result of an angular or linear displacement.
The position encoders can be grouped into two categories:
- Incremental encoders, which detect changes in displacement from some datum position.
- Absolute
