Combustible gas detectors |
| abstract |
The invention relates to combustible gas detectors of the kink in which a heatable wire filament exhibits a change in resistance due to a change in its temperature caused by the oxidation of a combustible gas passing over it. In order to avoid poisoning the heatable wire filament is embedded in a pellet consisting of a homogeneous mixture of an oxidation catalyst material and zeolite material the latter preferbly of type X, Y, L or mordenite of large pore size. Additionally layers of catalytically active material and/or inactive non-catalytic porous material may be provided around the outside of the pellet. |
