Position Monitors

The Motrona range of position monitors are used 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 suitable for monitoring and avoiding misalignment, shaft breakage, torsion and slippage.

The high frequency range, fast response and ease of adjustability of the speed, direction and standstill parameters are the key features of the Motrona position monitors.
