Speed monitoring
Speed sensors and monitoring relays track rotational speed and signal standstill or operation outside configured limits. Measurement can use pulses from a proximity sensor or encoder, evaluated directly or by a dedicated module. Applications include motors, fans, mixers and conveyors, including detection of lost motion. Selection requires checking pulses per revolution, speed range, input frequency and start-up delay. Thresholds, hysteresis and output type are configured to suit the process and the characteristics of the rotating equipment.
