Abstract
A solid electrolyte oxygen gas sensor element 1 comprises an electrolyte body 3 having electrodes 7 and 11 on the outer and inner surfaces 5 and 9 thereof, with the inner surface 9 having a protective means 13 thereon to protect the same from contact with oxygen or oxygen-containing gases so as to provide a substantially zero oxygen reference for the inner surface. The protective means 13 can comprise a coating, or a packing within a tubular electrolyte body, of carbon or a metal which forms an oxide that is stable at the operating temperature of the oxygen sensor element.
