The working principle of the Steam turbine Rotation Speed Gauge meter HZQW-03A is that when the impactor of the emergency breaker is knocked out, the sensor will detect the signal. The frequency of this signal is 49-60 HZ, and the detected signal is counted and identified by the microprocessor after shaping. When the identified pulse is confirmed to be the signal of the emergency breaker striker flying out, the rotational speed when the first pulse signal is received is immediately memorized in the memory. When the rotating speed drops and the impactor retracts, the rotating speed at this moment is also stored, and the data can be reproduced on the display screen by operating the keys on the instrument panel.

 

Alarm function of HZQW-03H Steam turbine Rotation Speed Gauge meter: the alarm value can be set, and once the monitoring parameters exceed the set value, an alarm signal can be sent in time.

 

Measuring range of HZQW-03H Steam turbine Rotation Speed Gauge meter: the range of parameters that the steam turbine monitoring device can measure, such as speed, temperature, pressure, etc. The precision and accuracy of the measurement results of the steam turbine monitoring device are usually expressed in percentage or several decimal places. The sampling frequency of the HZQW-03H tachometer is usually expressed in Hertz (Hz). The higher the sampling frequency, the finer the data, which can more accurately reflect the operating status of the steam turbine.
