Đo tốc độ YOYIK tachometer HZQS-02H turbine speed monitoring device 0-9999r/min

The tachometer HZQS-02H is used to monitor the turbine speed and impactor. Its number of teeth can be adjusted by itself, or it can be set at the factory according to customer requirements. The tachometers are all equipped with reluctance type tachometer probes. If there are no special requirements, they are all 75 in length. If there are special requirements, they can also be customized according to the actual needs of the power plant.
