ABSTRACT:
A self-contained, integrated-structure, miniature, electrochemical-type oxygen sensor is described which uses an oxygen ion conducting solid electrolyte. An encapsulated metal-metal oxide reference electrode on one surface of the solid electrolyte provides a reference oxygen pressure. A sensing electrode is placed on the other surface. The voltage developed between the reference electrode and the sensing electrode is indicative of the oxygen content of the fluid the sensing electrode is contacting.
