HYDROGEN GAS ANALYSER Russian patent published in 2009 - IPC G01N27/14 

FIELD: physics.

SUBSTANCE: invention can be used for monitoring gaseous atmosphere in industrial buildings with dangerous working conditions, particularly for providing for hydrogen explosion safety under the containment shell of a nuclear power plant and explosion-proof compartments. In the hydrogen gas analyser, which has a sensor compartment which can be linked to the monitored volume, the sensor compartment has a sensor and porous or diffusion membrane wall which is selective towards hydrogen. The sensor compartment is filled with hydrogen-sensitive substance with exothermal response. The sensor is made in form of at least one thermocouple or thermistor. The membrane wall is made from shock-resistant material. The sensor compartment has an airtight cartridge with a holding bracket for joining to the monitored volume.

EFFECT: design of a reliable, simple and cheap gas analyser with long service life.
