The speed monitors of Motrona’s DZ series are designed for installation in control cabinets. They are used to monitor overspeed, underspeed, direction of rotation or standstill of machines. Special models of speed monitors, which have an analogue output, can also be used for control tasks.

The special features of their speed monitors are the very high-frequency range, the fast response and the easy adjustability of the speed, direction and standstill parameters depending on the used input signals.
