5.1.2 Service life
Expected life is 3 years or more and is application and maintenance dependent.
The sensor signal deteriorates relatively quickly at the end of the service life of the sensors.
The electrode evaluation in %, therefore, can only be used as a guide value. A value of 70%
does not mean that exactly 70% of the service life is still available, rather that the electrode
signal has 70% of a comparison signal.
Note
The sensor evaluation is updated by the measuring device after a successfully performed
calibration of the oxygen sensor.
The nominal service life can be reduced significantly due to use.
Influential factors include:
Storage / operating temperature
Contamination of the measured water
Mechanical stress of the sensor membrane
Storage in dry air
Continuous use in elevated carbon dioxide concentrations.
5.1.3 Operating position
The oxygen sensor should be arranged vertically upwards with the connecting cable.
A slight angle of inclination does not impair the measurement.
5.1.4 Residue
Significant deposits on the membrane and
matt platinum electrode.
Deposits already have an effect on the measurement.
=> Carry out
maintenance to remove these.
Slight deposits on the edge of the electrode, predominantly
blank
platinum electrode.
No significant influences on the measurement to be expected.
=> Maintenance not absolutely necessary..
Deposits on the membrane, bare platinum electrode.
=> no maintenance required.
Polished platinum electrode during
maintenance.
Before screwing the membrane head on sensor body again they should be washed off, to
avoid them getting in between platinum cathode and membrane.
