4B introduce new maintenance tool

4B Braime Elevator Components launch new speed switch sensor testing and calibration device

4B Braime Elevator Components Ltd, worldwide manufacturers of material-handling and electronic components for bucket elevators and conveyors, have developed a new maintenance tool designed to make the testing of 4B speed switch sensors quick, easy and accurate.

The SpeedMaster is the only device that accurately tests the calibration of speed switches and their alarm and shutdown under-speed relays. It 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 under-speed 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 SpeedMaster.

Maintenance and safety personnel can now quickly, easily and accurately test 4B speed switches during recommended inspection schedules.
