7. Maintenance and cleaning
7.1 Maintenance
When used in strongly contaminated and adhesive media, the pressure port of the submersible pressure sensor has to
be cleaned regularly. The cleaning interval is dependent upon the respective application. The checking and cleaning of
the pressure port should thus be added to the maintenance plan.
Since the cleaning intervals are dependent on the operating conditions, no universal time periods can be specified.
Repairs must only be carried out by the manufacturer.
