Control Concepts, Inc. Rotoguard® III S-X-3-B-1-D-1

The Rotoguard III is a switch device for sensing the reduction, increase or loss in rotational motion for many types of moving equipment. The unit can detect changes in motion between 1 and 400 RPM depending on the model selected. The Rotoguard III may be direct coupled or driven through belts and chains. There are three basic models from which to choose. The Zero Speed unit offers no calibration where shaft alarm speeds are near zero RPM. The Adjustable Alarm Speed model offers economy where an alarm is needed with a 15% or greater change in speed. The Digital Set Alarm Speed offers precise and easy adjustment for alarms with as small as a 3% change in operating speed.
