ABSTRACT:
This device provides an electric signal linearly dependent on the oxygen content of a gas without the need of a reference gas; it is constituted by a solid electrolyte substrate (3) coated with two separate electrodes (1,2) connected to the terminals of an electric voltage source. In the presence of a gas of which the content of oxygen must be measured and when a given voltage is applied between the two electrodes (1,2), oxygen molecules are ionized in the region of the electrolyte close to the cathode (1). The current which flows between the two electrodes (1,2) constitutes the measuring electric signal provided by the sensor.
