Speedetex® MSS Mechanical Speed Switches On TORQ Corporation

Protect Your Equipment with TORQ Speed Switch Underspeed and Overspeed Models

The TORQ Speedetex® MSS Mechanical Speed Switch is used in bulk material handling/processing systems to monitor speeds of belt conveyors, screw conveyors, bucket elevators, rotary feeder shafts, rotating drums and other types of rotating machinery to protect elevators, feeders and conveyors from speed related damage resulting from broken belts, overloads, or belt slippages.

The MSS mechanical speed switch activates at an RPM specified by the user. Each unit is designed with a spring and weight combination to detect either underspeed or overspeed. Output is a hard contact closure - SPNO, SPNC, or SPDT as specified by the user.
