HYDROGEN DETECTOR IN LIQUID AND GAS MEDIUMS Russian patent published in 2010 - IPC G01N27/417 

FIELD: measurement equipment.

SUBSTANCE: hydrogen detector in liquid and gas mediums includes selective membrane (11), porous electrically insulated ceramics (7) and body (5) with potential collector (9), ceramic sensitive element (4) with reference electrode (14), porous platinum electrode (8), siliceous cloth (6), connecting material (12), plug (10) with hole, feedthrough plate (2), cylindrical bush (1). Cavity of body (5) between feedthrough plate (2) and ceramic sensitive element (4) is tight. Ceramic sensitive element (4) is arranged in the form of joined cylindrical element and sphere part located in lower part of cylindrical element. Upper part of external cylindrical surface of ceramic sensitive element (4) is tightly connected to body (5) by means of connecting material (12). Reference electrode (14) is installed in cavity produced by internal surface of ceramic sensitive element (4) and plug surface (10). External spherical part of ceramic sensitive element (4) is coated with a layer of porous platinum electrode (8). End of central core (13) goes through hole in plug (10) into volume of reference electrode (14). Bush (1) is connected to lower part of body (5).

EFFECT: expansion of functional resources, reduction of cost and improved efficiency of detector.
