Zirconium dioxide Lambda probes: measuring oxygen in the exhaust of vehicles

Picture of Zirconium dioxide Lambda probes
They consist of a solid electrolyte of zirconium, ion-conducting material of oxygen from 300 ° C.

The oxygen content in the exhaust gas is measured by electrodes placed on the inner side (reference/ambient air) and in the part of the exhaust (gas measuring).

The output signal is created with the oxygen ions that move by the element and try to make up the difference of oxygen (difference in the partial pressure of oxygen).

Its features include a quick start-up, heat resistance, shock of water and toxicity and a high degree of reliability.
