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.
