| 摘要 |
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 said metal casing; a detection module sensitive to a combustible gas; a compensation module insensitive to a combustible gas and matching said detection module; wherein said detection module has a higher catalytic combustion activity than said compensation module; a sealant, wherein a bonding length of said sealant in said accommodation space of said metal casing is used as an effective bonding surface, and said effective bonding surface is perpendicular to said transfer surface. As compared with the prior art, the present invention has the advantages of a miniaturized size, good explosion-proof property and reliable performance. |
