Speed ​​monitoring device HZQS-02A

The number of teeth of the steam turbine speed monitoring device HZQS-02A can be adjusted by itself, or it can be set at the factory according to customer requirements. The number of teeth used in power plants is as follows: 60 teeth, 88 teeth, 96 teeth, etc., and 30 teeth are almost never used.
The steam turbine speed monitoring device HZQS-02A is used in conjunction with the reluctance speed sensor for measurement. The number and type of speed sensors used for measurement are determined according to the actual working conditions of the power plant.
When the speed sensor is installed at a distance of 1.0mm, it has high resistance and high amplitude; when the speed sensor is installed at a distance of 1.5~2mm, it has low resistance and low amplitude.

The speed monitoring device HZQS-02A is used in steam turbine supervision and protection projects:

Oil engine stroke: display and signaling.

Synchronizer travel: displayed.

The main valve of the high and medium pressure cylinder is closed: signal.

Main tank oil level: displayed.
