The Turbine Rotation Speed Impactor Monitor HZQW-03E is a device used to monitor the speed of the steam turbine unit during operation. When the emergency governor knocks out, the sensor detects this signal. The frequency of this signal is between 49 and 60 Hz. The signal detected is shaped and counted and monitored by the microprocessor. When the identified pulse is confirmed to be the signal of the emergency governor impactor flying out, the speed at which the pulse signal was received is immediately memorized in the memory. When the speed drops and the impactor retracts, the speed at this time is also stored. The above data can be reproduced on the display screen by operating the buttons on the instrument panel.

.

The Turbine Rotation Speed Impactor Monitor HZQW-03E is used for measuring the speed of 300MW and 600MW feedwater pump steam turbines at 30 teeth. This device is a high-performance microcomputer intelligent digital display instrument. The instrument usually displays the turbine speed, and the internal memory function can store the emergency governor impactor's "strike out", "retract", and the unit's "" speed in the instrument.
