DEVICE FOR DETERMINING OXYGEN AND HYDROGEN CONCENTRATION IN GAS MEDIUM Russian patent published in 2014 - IPC G01N27/417 G01N27/26 

FIELD: chemistry.

SUBSTANCE: device for determining the oxygen and hydrogen concentration in a gas medium relates to measurement instruments and can be used for control of gas media parameters, in particular of those, containing oxygen and hydrogen. The device consists of a channel (7), located at an angle to the horizon, an input hydrogen sensor (2) and an input oxygen sensor (3), located in the input part of the channel (7) cavity, an input catalytically active element (1), installed in the channel (7) cavity above the output sensors of hydrogen (2) and oxygen (3), an output hydrogen sensor (5) and an output oxygen sensor (6), located in the channel (7) cavity between the input (1) and output (4) catalytically active elements. The input (2) and output (4) catalytically active elements are made of highly porous cellular materials with a platinum coating applied on their surface. As the input hydrogen sensor (5) and the output hydrogen sensor (7) used are solid electrolyte sensors of the hydrogen concentration with a ceramic sensitive element, made of oxygen-conducting ceramics.

EFFECT: increased speed of the device performance and sensitivity, provision of protection against erroneous readings of the device.
