Abstract
A sensor housing system maintains a sensor—which is used in monitoring an extreme temperature environment such as a combustion unit—at a desired ambient temperature. The system comprises one or more sensors housed within an internal chamber and cooled by air or an inert gas. Gas within the chamber cools the sensor and then exhausts to a second internal chamber which, in turn, exhausts to atmosphere. Both chambers are housed in a directional ball pivot that provides access to the extreme temperature environment and adjusts the angle of the sensor. An air tube having a sweep is directed toward the external surface of the glass wafer and directs a hot gas stream across the surface of the wafer. A failsafe device retracts the chambers from the extreme temperature environment in case of power failure or if for some reason the sensor becomes too hot.
