Multiple chamber dual channel infrared gas detection system |
摘要 |
A gas sensor usable in harsh environments includes a multiple chamber radiant energy transmission path which extends between a multi-channel emitter and a multi-channel detector. Chamber length and gas selection are establishable using a movable element with an aperture. The element is located between the emitter and the detector on the transmission path. Radiant energy from the emitter is reflected between the emitter and the element, prior to passing through the element to impinge on the detector.
