The CCC® Model RMS Non-Contact Motion Control indicates when a rotating shaft has slowed or quit moving altogether. It can shut down rotating equipment before damage is encountered and provides protection for interlocked conveyor belts, especially if one of the belts fails due to overloading or tearing. The unit can be adjusted as an oversped, underspeed, or zero speed control. The output contacts of the Model RMS can control up to two separate circuits, one for machinery shutdown and one for an alarm.
