Wear Resistant Non-Contact Temperature Sensors are used where control and position sensing systems with analogue output provide a signal that is proportional to the travel distance. These Temperature Sensors combine features like repeat accuracy, resolution and linearity. These Temperature Sensors have high electro-magnetic compatibility and stability over a wide temperature range. Wear Resistant Non-Contact Temperature Sensors are based on various different physical operating principles comprising of magneto-strictive, magnet-inductive, photoelectric and ultrasonic sensing methods.
