 The Rotospeed Switch was developed initially to economically monitor Rotolok's Rotary Valves around the clock, replacing labour intensive visual supervision. Other applications (e.g. belt conveyors, elevators and vee drives) however require more sophisticated overspeed and underspeed detection, so the Rotospeed has been upgraded to meet these needs.
