Abstract
The present invention provides an explosion-proof miniaturized combustible gas sensor, comprising: a metal casing having an accommodation space therein; a wire mesh, a vertical surface perpendicular to a side surface where the wire mesh is located and the other side surface opposite thereto being used as a transfer surface of the combustible gas; a heat insulation module embedded in the metal casing; a detection module sensitive to a combustible gas; a compensation module insensitive to a combustible gas and matching the detection module; where the detection module has a higher catalytic combustion activity than the compensation module; a sealant, where a bonding length of the sealant in the accommodation space of the metal casing is used as an effective bonding surface, and the effective bonding surface is perpendicular to the transfer surface. The present invention has the advantages of a miniaturized size, good explosion-proof property and reliable performance.
