WHAT IS IT?
The Model MSD is comprised of two different components, a control unit (digital display) and a speed sensor (pulse generator). The Model MSD-800 control unit is a programmable unit that has two setpoints permitting it to indicate two under-speed points or two over-speed points, or one of each. The control unit acts as a digital tachometer that constantly displays the actual speed of the equipment being monitored. The Model MSD-1 speed sensor installs directly to the shaft of the rotating equipment to be monitored and is enclosed in a rugged cast aluminum housing designed to withstand harsh environments.
WHY IS IT NECESSARY?
The Model MSD alerts the operator of a change in rotary speed. It sends a signal to the control unit which can be used to sound an alarm and/or shutdown the equipment completely. By monitoring speed you can greatly reduce system and equipment downtime by fixing malfunctions such as broken drive gears or belts, overworked motors, belt overload and other problems before serious damage occurs.
