This deivce can precisely and automatically control the the Nitrogen / Hydrogen percentage of this mixing protective gas.
The N2 and H2 flow into the mixing tank from its own pipe, and a part of the gas sample is measured by the thermal conductivity hydrogen analyzer. And then the analyzer sent the electrical signal to the controller for comparing with the set value of hydrogen content, finally the opening of hydrogen valve is controlled by PID regulator to reach the setting value.
Capacity | 10-1000Nm3/Hr |
Pressure of Mixing Gas | 0-1.0Mpa |
Hydrogen % | 0-100%(±0.5%) |
