Title: Gas sensor elements and methods of manufacturing them
IPC: G01N27/16
Filed: 1980-12-18
Abstract: A gas sensor element for detecting the presence of a flammable gas comprises an electrical resistance filament 1 surrounded by a bead 2 which is formed by an array of alumina particles interspersed between and bound together only by particles of a catalyst for inducing catalytic oxidation of flammable gases to form an open porous gas diffusive skeletal matrix having a mean particle size of less than 20 nm. When the bead includes such a matrix, the number of active sites at which catalytic oxidation of flammable gases can take place is greatly increased with the result that the sensor element is very resistant to poisoning by atmospheric contaminants such as traces of silicone and sulphur compounds. The sensor thus has a very much longer life and does not require such frequent recalibration. <IMAGE>
