Oxygen Sensor Design
The device most widely used at present consists of a stabilised zirconia electrolyte tube
with platinum electrodes deposited on the inner and outer surfaces. With different pO2 on
inner and outer surfaces an EMF is generated. If carbon monoxide is present a further
reaction is possible:
CO (gas) + O2 (electrolyte) -> CO2 (gas) + 2e- (electrode)
The catalytic reaction at the platinum electrode
CO (gas) + ½ O2 ->CO2
can minimise the above effect. Further reactions can occur when H2, H2O and NOx are
present. The successful application of an exhaust monitor requires a simple and
inexpensive device which is able to operate in a harsh environment at temperatures in the
region of 900°C in the presence of thermal shock.
A typical sensor is shown in the diagram, figure 2, with the format being similar to an 18mm
diameter sparking plug.
