XACT500-HA Generator hydrogen control device

XACT500-HA Generator hydrogen control device

Product introduction

XACT500-HA Generator hydrogen control device is an integrated detection system exclusively for detection of gas purity and pressure signal inside the generator. The core purity component applies XACT500 digitization online gas purity transmitter which can measure the content of a certain gas in two-component mixed gas, as well as the content of a certain gas in multi-component mixed gas with large differences in thermal conductivity coefficient. 

By adoption of 2 XACT500 digitization online gas purity transmitters, XACT500-HA Generator hydrogen control device is capable to measure the content of air and H2 in CO2 gas and the purity of H2 in air accurately in large scale. With the help of the pressure regulating valve in differential pressure transmitter, the measurement of differential pressure on generator turbine’s front and rear blades can be achieved. Through the adjustment of flow control valve and globe valve, H2 purity in two oil return gas chamber of sealing oil of the generator can be continuously monitored. The contents of the generator internal H2, CO2 and air also can be measured through the regulating switch of valves, to fulfill the control of gas purity pressure under high-risky, closed, independent or continuously working environments.

 


Performance characteristics

With characteristics of excellent stability, anti-disturbance ability and super oil-pollution resistance

With functions of digital signal output and analog signal output, data can be directly sent to DCS as well as data communication with remote computer

With functions of remote switch and remote control

The differential pressure transmitter bears excellent performance accuracy to optimize the performance of the circuit with faster dynamic response, so the calibration and maintenance costs will be greatly reduced correspondingly.
