Planning instructions for diaphragm seal systems
NOTICE
Diaphragm seal systems sized/ordered incorrectly
The performance and the permitted range of application of a diaphragm seal system depend on the
process isolating diaphragm used, the filling oil, the coupling, the unit design and on the specific
process and ambient conditions present in the individual application.
‣
To help you select the right diaphragm seal systems for your particular applications, Endress
+Hauser provides its customers with the "Applicator Sizing Diaphragm Seal" selection tool, which
is available free of charge at "www.endress.com/applicator" or as a download.

Applications
Diaphragm seal systems should be used if the process and the device need to be separated.
Diaphragm seal systems offer clear advantages in the following instances:
• In the case of extreme process temperatures
• For aggressive media
• If extreme measuring point cleaning is necessary, or in the event of very damp mounting locations
• If the measuring point is exposed to severe vibrations
• For mounting locations that are difficult to access
