The zirconium-oxide measuring principle is used for O2 measurements in especially combustion processes for use of control and optimisation of the process. The zirconium oxide probe has a platinium-coated ceramic measuring element that can conduct oxygen ions at temperatures typically above 600 °C. In the measuring element, one side is filled with atmospheric air with a known O2-concentration (20.9 vol%), and on the other side the O2-concentration is to be measured. Since the partial pressure of O2 is different from one side to the other, the O2-molecules will try to establish a equilibrium by moving from one side to the other. The movement of O2-molecules makes a difference in voltage which is equivalent to the O2-concentration in the process.
