RotoGuard® IV Speed Switches
The RotoGuard® IV is an electronic speed switch device for sensing the reduction, increase, or loss in rotational motion associated with many types of moving equipment. The unit can detect changes in motion between 1 and 400 RPM, depending on the model selected, and provide a change of state, or alarm, when a variation in operating speed occurs. The RotoGuard® IV may be direct coupled to another shaft or driven with a belt or chain.
