    2.2 Precise Paramagnetic Sensor 2.2.1 Principles of Operation The heart of the 3020M is a paramagnetic type oxygen sensor that is maintenance free and has a long lifetime. Both the standard 3020M sensor (P/N S1731) and the 0-1% sensor (P/N S1638) are both paramagnetic sensors however the sensors are different and not interchangeable.

The difference between the compensating currents required to bring the dumbbell to the zero position in the presence of zero gas (i.e. no O present) or of sample gas is proportional to the partial pressure of oxygen in the sample gas.
