Đo tốc độ YOYIK Tachometer RZQW-03A speed 0-3300r/min turbine speed impact sub-monitoring device

The tachometer RZQW-03A is used when the emergency breaker striker is struck out. ZS-03 detects this signal. The frequency of this signal is 49-60HZ. The detected signal is counted and identified by the microprocessor after shaping. When the identification When the pulse sent out is confirmed to be the emergency breaker striker flying out signal, the rotational speed when receiving a pulse signal is immediately memorized in the memory. When the speed decreases 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 RZQW-03A tachometer is an important operation monitoring item of the steam turbine unit. The emergency breaker is one of the main components of the security system. When the unit speed exceeds 10% of the rated speed, the emergency breaker RZQW-03A striker is knocked out to ensure the unit's safety . completely. The storage environment of the ZS-02 speed sensor: it must be ensured that there is no corrosive environment, no strong magnetic field, etc.; the storage temperature is -40 to 60°C, and the relative humidity is: 30 to 90%.
