position guard
The position monitors are able to determine actual
values such as speed, direction of rotation and
standstill and compare them with specified target
values. In the event of an unwanted movement,
the devices trigger a programmed error message.
These safety relays are therefore suitable for
monitoring and avoiding misalignment, broken
shafts, torsion and slip, among other things.
The high frequency range, the fast reaction and the easy
adjustability of the speed, direction and standstill
parameters are some of the features that make our
position monitors special.
