M300 Slipswitch
Detect Dangerous Underspeed Slow Down Conditions
APPLICATION
The M300 Slipswitch is a simple inductive shaft speed monitoring device. The self-contained unit has a single set point, which signals when the shaft speed has dropped by 20% of normal running speed. It is used for detecting dangerous slow downs and underspeeds on conveyors, bucket elevators, airlocks, industrial mixers, industrial fans, industrial grinders and many other machines.
METHOD OF OPERATION
An inductive sensing device located in the nose of the M300 enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft. During installation the M300 is set to the normal machine shaft RPM by calibrating with the magnet provided. The internal microprocessor sets the underspeed output to operate at exactly 20% below normal machine shaft RPM, so users are able to use the M300 output for automatic shutdown during a dangerous underspeed or belt slip condition.
