Rotational speed monitors
Speed monitors detect overspeed and underspeed conditions
In many industrial applications, drives are monitored for rotational speed or standstill. In the automotive, food, steel and mining industries, speed sensors are used to safely detect standstill, overspeed and underspeed of drives or belt break on conveyors. On mobile machines such as fork-lift trucks, speed sensors serve as speed pick-ups.
The compact speed monitor generates a pulse train each time a target passes, evaluates the signal, and determines if the speed is above or below the set point.
