7.5 Replacing the Electrochemical Sensor
7.5.1 General Hints on Handling the Sensor
Do not expose the sensor to a temperature other than the temperature range of -20 to
+60‘C (-4 to +140 F). Exposing to a temperature outside the temperature range may
cause abnormal output or leak of the electrolyte due to parts degradation or damage.
Make sure to prevent condensation of the oxygen concentration detecting part. If
condensed, the output will lower and response speed will slow down, disabling accurate
concentration measurement. The sensor characteristics will return to the original
characteristics if condensation moisture evaporates after putting the sensor in dry air
several hours to several days.
Do not drop or apply a violent shock or vibration to the sensor. If shocked or vibrated, the
sensor output may temporarily vary or become unstable. The original sensor condition
will usually reset by putting the sensor in a stationary condition in the atmosphere at
a ordinary temperature several hours to several days. Depending on the degree of a
shock or vibration, the internal sensor structure may break and the sensor may not
return to original condition.
