Speed Switch Calibration and Testing Device
SM2, SM1

The SpeedMaster™ with Pulse Pilot is the only device that accurately tests the calibration of a speed switch, and allows testing of the 10% alarm and 20% shutdown features of the sensor while installed on the machine shaft.

The SpeedMaster™ operates in two modes. Input mode is used to measure the pulse rate at normal speed. Output mode will allow the user to simulate belt underspeed for testing purposes.

The Pulse Pilot fits between the gap between the sensor and the target. The Pulse Pilot will have no effect on the operation of the speed switch until it is connected to the SpeedMaster™ and set to Output mode.

    Do I need to remove any parts from my Whirligig / Speed Switch assembly in order to use the SpeedMaster™?  

      No, one of the features of the SpeedMaster is that you can test the 4B Speed Switch without changing the installation or wiring of the sensor.  

    Do I need to stop the machine before I can use the SpeedMaster™ for diagnostics?

      No, the Pulse Pilot of the SpeedMaster™ can be inserted between the Whirligig and Speed Switch while the machine is running.
