4B SpeedMaster - Speed Switch Sensor & System Testing Device

The 4B SpeedMaster™ with Pulse Pilot provides independent, real time, and complete verification of an entire speed monitoring system to ensure that alarms and shutdowns are working as expected.

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 input pulses to the sensor for testing purposes. The Pulse Pilot fits in the gap between the sensor and cover on the Whirligig®.

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.
