without taking the transmitters out of the process.

8.1.1
Deltabar FMD77, FMD78
We recommend you perform CIP (cleaning in place (hot water)) before SIP (sterilization in
place (steam)) for pipe diaphragm seals.
A frequent use of sterilization in place (SIP) will increase the stress on the process isolating
diaphragm. Under unfavorable circumstances in the long term view we cannot exclude that
a frequent temperature change could lead to a material fatigue of the process isolating
diaphragm and possibly to a leakage.
8.2
Exterior cleaning
Please note the following points when cleaning the device:
• The cleaning agents used should not attack the surface and the seals.
• Mechanical damage to the process isolating diaphragm, e.g. due to pointed objects, must
be avoided.
• Observe degree of protection. See therefor nameplate if necessary (
