THERMOCHEMICAL SENSOR Russian patent published in 2013 - IPC G01N27/16 

FIELD: chemistry.

SUBSTANCE: thermochemical sensor has a measuring circuit consisting of a working element and a comparative element, each in form of a resistor which is in form of a heating coil which is baked inside a porous carrier, in the working element of which the porous carrier is coated with a catalytically active layer, and in the comparative element the porous carrier is coated with a catalytically inactive layer; in the working element between the porous carrier and the catalytically active layer there is an intermediate layer with the composition BaO(CeO)_0.9(Nd₂O₃)_0.1; and the material of the catalytically active layer used is the composition (La₂O₃)_0.6(SrO)_0.4MnO₂.

EFFECT: wide range of measuring concentration of hydrogen-containing combustible gases.
