Conveyor motion control

The new Model MSD-800 series motion sensing controls protect indoor and outdoor rotating equipment such as screw conveyors, belt conveyor pulleys, rotary feeders and bucket elevators from costly damage by continuously monitoring rotary speed. They alert the operator of a change in speed by sending a signal to the control unit, which can be used to sound an alarm and/or shut down the equipment completely. By monitoring speed, plant operators can greatly reduce system and equipment downtime by fixing malfunctions such as broken drive gears or belts, over-worked motors, belt overload and other problems before serious damage occurs.

Conveyor belt speed sensor

The Model BSD (belt speed detector) is a “traction action” motion control that indicates when a conveyor belt has slowed or quit moving altogether. The unit can be adjusted as an overspeed, underspeed, or zero speed control. The output of the Model BSD can be wired into a PLC or DCS, or to the optional RMS controller, which has a DP/DT relay to control up to two separate circuits, one for machinery shutdown and one for an alarm.
