SO-A0-250 Limiting Current Type Zirconia Oxygen Sensor Operational Principle
When voltage is applied to a zirconia electrolyte cell, oxygen is pumped through the zirconia disc from the cathode side to the anode side because the carriers of the current flowing through the zirconia electrolyte are oxygen ions. By attaching a cap with a pinhole on the cathode side of the cell and by increasing the voltage over the cell the current shows saturation due to the rate limiting step in the transfer of oxygen to the cathode. This saturation current is called limiting current and is nearly proportional to the ambient oxygen concentration.
Below the advantages of the Zirconia Oxygen Sensor SO-A0-250:
* Measuring range 0.10 to 25.0 vol.% oxygen
* High accuracy
* For many types a more or less linear characteristic
* Small temperature dependence of the sensor signal
* Low interference with other gases
* Long service life
* In many cases "Single point calibration" necessary only once
