Galvanic cell principle: (O2) Galvanic cell oxygen sensor structure: A polytetrafluoroethylene breathable film with a thickness of 10-30 microns that is good for oxygen permeability is installed on one side of the plastic container. A cathode of precious metal (platinum, gold, silver, etc.) is placed close to the inside of the container, and an anode is formed on the inside of the other side of the container or in the free part of the container (large metals are ionized with lead and cadmium plasma). When oxygen passes through the electrolyte, a redox reaction occurs at the cathode and anode, ionizing the anode metal and releasing electrons. The size of the current is proportional to the concentration of oxygen. Since the anode metal is consumed during the entire reaction, the sensor needs to be replaced regularly.
