An oxygen sensor based on electrochemical pumping is described which is capable of measuring with high sensitivity A/F over an extended range from very lean to very rich A/F values. The sensor output is approximately proportional to A/F, has a weak dependence on temperature and is essentially independent of the gas pressure.
