10.2.1

Defining the maintenance interval

No maintenance interval has been defined
Device failure, device damage, and risk of injury.
• Define a maintenance interval for regular tests in line with device use and empirical
• The maintenance interval will vary from site to site depending on corrosion resistance.
10.2.2

Checking the gaskets

Note
Checking the gaskets
At regular intervals, check that the enclosure seals of the pressure transmitter satisfy IP66 /
IP68. Grease or replace the gaskets if required.
10.2.3

Changing the measuring cell and application electronics

Related
Each of the individual components "Measuring cell" and "Electronics" has a non-volatile
memory (EEPROM).
Measuring cell data (e.g.: measuring range, measuring cell material, oil filling) and user data
of the application electronics (e.g.: downscaling, additional electrical damping) are located in
the measuring cell EEPROM. User data is lost when the measuring cell is replaced.
Application-specific data are not lost when the application electronics are changed.
You can backup user data before changing the measuring cell and reload it afterwards. Use
an input device which supports the HART protocol. (e.g. HART communicator, PC with
HART modem and HART software or PC with HART modem and PDM software). Factory
settings will be used if user data is not backed up before the measuring cell is changed.
Technical developments enable advanced functions to be implemented in the firmware of the
measuring cell or application electronics. Further technical developments are indicated by
modified firmware statuses (FW). The firmware status does not affect whether the modules
