MTS Temposonics ® R-Series magnetostrictive absolute non-contact displacement sensor

Core technical principles

Magnetostriction effect:

The core components are waveguide wires and external permanent magnets

The current pulse generates a magnetic field in the waveguide wire, which interacts with the magnetic field of the magnet to generate stress pulses

The stress pulse propagates at a constant speed of about 2780m/s, and the absolute position is calculated by the time difference

Features: Non contact, wear free, absolute measurement, read immediately upon power on, zero free return
