The utility model discloses a kind of firedamp sensors for preventing blocking vapour corrosion, it solves the problems, such as that there are vapour corrosions and coal dust blocking probe for firedamp sensor in the prior art, with the beneficial effect for guaranteeing firedamp sensor sensitivity, its scheme is as follows: a kind of firedamp sensor preventing blocking vapour corrosion, including upper housing and lower case, upper housing and lower case fasten, setting gas management is popped one's head in lower case, the controller of setting and gas management probe connection in upper housing, lower shell surface has air hole, the first shell around gas management probe setting is equipped in lower case, the dry part of setting first in first shell, first shell is equipped with hole, setting is for drying the heating element of the first dry part in lower case. |
