Elevator & Conveyor Maintenance

Speed Switch Sensor Testing and Calibration

07/18/2013 | Editor: Marcel Dröttboom

4B Braime Elevator Components, a worldwide manufacturer of material handling and electronic components for bucket elevators and conveyors, has developed a new maintenance tool that makes the testing of 4B speed switch sensors quick, easy and accurate.

According to 4B Braime, the SpeedMasterT accurately tests the calibration of speed switches and their alarm and shutdown underspeed relays. The device operates in two modes; input mode provides the user with the machine's actual running speed, and output mode allows the user to test the speed switch at set underspeed trip points for real time verification of the monitoring system's alarm and shutdown functions.

There is no need to remove the sensor from the machine shaft or change any system connections in order to use the SpeedMasterT. Maintenance and safety personnel can now quickly, easily and accurately test 4B speed switches during recommended inspection schedules.
