ABSTRACT:
A sensor is described for determining the oxygen content of a gas with the sensor consisting of a tablet of stabilized bismuth trioxide having electrode coatings on opposite major surfaces. The resistance between the electrode coatings is a measure of an oxygen partial pressure-dependent quantity. The tablet is immersed entirely in the gas to be analyzed so that the nesessity of a reference gas is eliminated.
