ABSTRACT:
The sensor includes a sensing element of a copper oxide ceramic with perovskite related structures. Electrical circuitry responsive to the conductivity of the sensing element is provided. This conductivity is a function of the gas partial pressure. A preferred ceramic oxide is in the Y-Ba-Cu-O system and these compounds exhibit a markedly greater dependence of conductivity on oxygen partial pressure than materials previously used.
