Operational Theory
is over 4.447 ppm/nA, a sensor failure alarm is triggered, indicating that
the cell should be replaced.
Figure 2-3. Characteristic Input/Output Curve for a Typical
Note: The graph depicted is used to show the linearity between
output and oxygen concentration. The y-axis values
represent output from a generalized MFC and should not
be used to extrapolate the output of a particular cell.
In addition, since there is zero output in the absence oxygen, the
characteristic curve has an absolute zero. The cell itself does not need to
be zeroed.
