So B1 050 Limiting Current Type Zirconia Oxygen Sensor - China

SO-B1-050 Limiting Current Type Zirconia Oxygen Sensor

/

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.
