It functions as both an oxygen measurement device and an oxygen pumping device. In the measurement mode, the sensor will output voltage value that is a function of the oxygen partial pressure differential between the internal sealed reference chamber and the glue gas (Nernst voltage).
In the pumping mode, the sensor will pump oxygen into or out of the reference chamber as a function of the charge transferred to the sensor.
