Woodward's 8272-804 speed switch

Is a device used to monitor and control the speed of an engine or generator set. It is usually installed on power equipment such as gas turbines and diesel engines to trigger alarms or take control measures when the engine speed exceeds or falls below a set safety range.

Main function

1. Speed monitoring: The 8272-804 speed switch continuously monitors the engine speed. This is usually done by sensing the speed sensor on the engine.

2. Set point control: The user can set one or more speed thresholds. When the engine RPM exceeds or falls below these thresholds, the speed switch is activated.

3. Alarm and indication: Once triggered, the speed switch can sound an alarm, light an indicator, or send a signal to the control system to notify the operator or automatically perform a control action.

4. Safety protection: By timely alerting or controlling engine shutdown, the speed switch helps prevent the engine from running over speed, thereby avoiding potential mechanical damage or safety incidents.
