Combustible gas detectors |
摘要 |
A gas detector consists of a heatable wire filament which exhibits a change in resistance when its temperature rises due to the oxidization of a combustible gas pouring over it. The filament is embedded in a pellet consisting of a homogeneous mixture of an oxidization catalyst material and a substantially non-catalytic carrier material. A layer of the oxidization catalyst material is produced on the outside of the pellet.
