Understanding Oxygen Sensors
by Paul Raymaekers
The cell is in reality a current source, not a voltage source, that delivers a current that is relatively independent of the load applied to the sensor, that delivers a current that is almost perfectly proportional to the PPO2 applied to the sensor, but that is heavily influenced by temperature. So without controlling the temperature, or compensating the output for temperature changes, we can not use this sensor body for measuring PPO2 in a diving environment.
