HYDROGEN SENSOR IN LIQUID AND GAS MEDIA Russian patent published in 2014 - IPC G01N27/417 

FIELD: instrumentation.

SUBSTANCE: invention relates to measurement equipment. Concept of the invention is as follows: a hydrogen sensor in liquid and gas media comprises a selective diaphragm (11), porous electric insulation ceramics (7) and a casing (5) with a potential measuring unit (9), a ceramic sensor (4) with a comparison electrode (14), a porous platinum electrode (8), siliceous textile (6), connection material (12), a plug (10) with a hole, a sealed lead-in (2), a cylindrical bush (1). The casing (5) cavity between the sealed lead-in (2) and the ceramic sensor (4) is leakproof. The ceramic sensor (4) is made as conjugated cylindrical element and part of sphere set in the lower part of the cylindrical element. The upper part of the outer cylindrical surface of the ceramic sensor (4) is coupled with the casing (5) by the connection material (12) in a leakproof way. The comparison electrode (14) is installed in the cavity formed by the inner surface of the ceramic sensor (4) and the surface of the plug (10). The outer spherical part of the ceramic sensor (4) is coated by a layer of the porous platinum electrode (8). The end of a central core (13) is led through the hole in the plug (10) to the cavity of the comparison electrode (14). The bush (1) is connected to the lower part of the casing (5).

EFFECT: expanded functionality; reduced cost and higher speed of sensor performance.
