MORTON, ILLINOIS, U.S. — 4B Components Ltd. announced on Nov. 25 that it has developed a new maintenance tool that makes the testing of 4B speed switch sensors quick, easy and accurate.

The SpeedMaster accurately tests the calibration of speed switches and their alarm and shutdown underspeed relays. The SpeedMaster 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 systems 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 and accurately test 4B speed switches during recommended inspection schedules.

“This new patent pending technology will change the way plants use underspeed monitoring systems and will make the plants safer,” said Johnny Wheat, 4B senior vice-president.
