So-e2-960 Limiting current type sensor oxygen sensors 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 oxygen sensor: Measuring range 1.00 to 96.0 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 â??single point calibrationâ?? necessary only once Applications: Medical Laboratory Food industry Household/gastronomy Measuring technique Security technology/monitoring (electrical-) industry Characteristic data: Measuring gas: oxygen concentration Measuring medium: gaseous atmosphere Measuring principle: limiting current type sensor Measuring ranges: 1.00 - 96.0 vol.% o2 Response time (t90): 2 to 25 sec.
