ABSTRACT:
An oxygen sensor consisting of an oxygen ion conductive solid electrolyte member coated with a porous cermet structure which exhibits a metallic and ceramic skeleton develops a resistance change in response to a change in oxygen partial pressure at elevated temperatures. The resistance change, when coupled to an electrical circuit, provides an electrical indication of the oxygen partial pressure of the atmosphere contacting the oxygen sensor.
