The Rotation Detector will monitor any rotating shaft or pulley and will activate a relay if the rotation speed is outside the pre-programmed limits. It is normally installed and wired to start monitoring when a motor is started. If the sensor does not pick up a signal from a magnet mounted on the equipment, a relay will be activated which will shut the motor down. A 2-second time delay is used to prevent nuisance shutdowns. It is very easy to install the Rotation Detector with a CompuDry® Command Center.
A unique feature of the Shivvers Rotation Detector is that it will flash the indicator light for 5 minutes if it was the Rotation Detector that shut the equipment off. This saves valuable time when troubleshooting why the system was shut down.
