An inductive sensing device located in the nose of the Milli-Speed enclosure will detect a ferrous 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 machine’s normal running speed by simple magnetic calibration. The 4-20 mA output signal is automatically scaled for zero to full speed with over speed detection.
The Milli-Speed is fully encapsulated in a polycarbonate body that is corrosion and abrasion resistant, dust-tight and waterproof (IP67). Its approvals for explosive atmospheres include: ATEX, IECEx and CCCEx; Zones 20, 21 & 22 for dust and Zones 0, 1 & 2 for gas.
Additionally, 4B’s SpeedMaster can be used with the Milli-Speed to test the functionality after the initial installation and during routine maintenance procedures. The SpeedMaster is the only device that accurately tests the calibration of a speed switch, and allows testing of the alarm and shutdown features of the sensor while installed on the machine shaft.
