Milli-Speed Switch
Underspeed Monitor
M300M1V10AI

The Milli-Speed Sensor has a 4-20 mA output proportional to calibrated speed, it is designed to allow detection of belt slip & underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders and many other rotating machines.  Totally sealed and simple to calibrate, the Milli-Speed works in the harshest of conditions.

An inductive sensing device located in the nose of the Milli-Speed enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft, such as 4B’s Whirligig® sensor mount. During installation, the Milli-Speed is set to the normal running RPM by simple magnetic calibration.
