The Speed Relay from HMA INSTRUMENTATION is a mechanical-type motion sensor for monitoring the operational speed of belt conveyors, cranes, and crushers, etc. It operates when the speed of the machine shaft becomes the set speed. Since the microswitch in Speed Relay is mechanically turned ON or OFF by induction torque generated by rotation of the permanent magnet, a power supply is unnecessary, while maintenance is easy.
