Position Monitors

The position monitors are able to determine actual values such as speed, direction of rotation and standstill and compare them with preset reference values. In the case of unwanted movement, the devices trigger a programmed fault message. These safety relays are thus suitable for monitoring and avoiding misalignment, shaft breakage, torsion and slippage.

The high frequency range, fast response and easy adjustability of the speed, direction and standstill parameters are some of the features that make our position monitors special.
