Pulse evaluation systems - Safe standstill monitoring



Safe standstill monitoring

The DA standstill monitor is a pulse evaluation system for safe detection of underspeed or standstill. It receives the pulses from the connected sensors serving as pulse pick-ups on the inputs and calculates the corresponding frequency. By continuously comparing the input frequency (actual value) and the switch point (preset value), the unit promptly detects underspeed or standstill.
For example, the standstill monitor can be used on a rotating machine part such as a drive, motor or shaft to determine whether it has been brought to a standstill due to a braking action. Any damage to persons or installations is reliably prevented.
