６－３．Replacing the sensor
６－３－１．Replacement intervals of the sensor
To maintain the reliability of the measurement, it is recommendable to replace the sensor
periodically. Our oxygen sensor has an enough life span. However, the actual life is
depending on the operating conditions. Then, replace the sensor once a year as the
tentative deadline for the replacement cycle.
* NOTE
・Output current corresponding to gas concentration is a linear and
obtained by following equation.
Output current (mA) = 4 + 16 x
Oxygen concentration (vol%)
Full scale concentration (vol%)
