Austria SENSORE zirconia oxygen sensor for oxygen concentrators, glove boxes, 3D printing, and air separation equipment - SO-E2-960

I. Working principle of the zirconia oxygen sensor SO-E2-960 for oxygen concentrators: 

BecauseSince the charge carriers in the zirconia electrolyte are oxygen ions, when a voltage is applied to the zirconia electrolytic cell, oxygen is pumped through the zirconia disc to the anode. If a perforated cap is placed on the cathode of the cell, the flow of oxygen to the cathode the rate at the electrode will be limited. Due to this rate limitation, as the applied voltage gradually increases, the current in the electrolytic cell will reach saturation. This saturation current is called the limiting current, which is proportional to the oxygen concentration in the surrounding environment. proportional to the degree.
