Abstract: A gas sensor comprises a cavity for containing a gas, means for generating radiation which is transmitted through the cavity and includes one or more wavelengths which is absorbed in use by a gas to be detected; and a detector for detecting radiation which has passed through the cavity. The walls of the cavity are sufficiently reflective to the radiation that the cavity is substantially uniformally illuminated with the radiation.

Abstract: An optical gas sensing apparatus (100) includes an explosion-rated device electronics enclosure (104). An explosion-rated sensing enclosure (108) has a light transmitting element (116) to allow light to pass out of and into the sensing enclosure. The sensing enclosure (108) is operably coupled to the explosion-rated device electronics enclosure (104) by a feed-through (122). In one aspect, an internal volume of the sensing enclosure (108) is less than or equal to about one fiftieth of the volume of the explosion-rated device electronics enclosure (104). In another aspect, the thickness of the light transmitting element (116) is less than or equal to about 3 millimeters. A light source (110) is disposed within the sensing enclosure (108) and is operably coupled to the device electronics (102). A detector (111) is disposed within the sensing enclosure (108) and is also operably coupled to the device electronics (102).
