The working principle is as follows: the conductive path is formed by means of the probe 15, an electron flow is generated between the anode and the cathode, and is linearly proportional to the amount of oxygen consumed, and the rate of oxygen passing through the membrane is proportional to the pressure to which the membrane is subjected; this is because oxygen is rapidly consumed at the cathode, and it is assumed that the oxygen pressure inside the membrane is zero, thus causing the oxygen to diffuse through the membrane with a force proportional to the absolute pressure of oxygen outside the membrane if the oxygen pressure increases. More oxygen diffuses through the membrane and produces more current, and vice versa the current decreases. The reaction equation is as follows:
cathode (Au) O2+2H2O+4e＝4OH-
Anode (Ag)4Ag +4Cl-＝4AgCl-+4e
The sensor is a special electrolytic cell, the anode of which is a large-area silver electrode, the cathode of which is a small-area gold electrode, and the supporting electrolyte is KCl solution.
