SpeedMaster™ Speed Switch Tester

The SpeedMaster™ is the only device that 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 system. There is no need to remove the sensor from the machine shaft or change any system connections in order to use the SpeedMaster.
