diaphragms, high-pressure
side
Note!
• Some device versions have CRN approval. For a CRN-approved device, a CRN-approved process connection
( ä 77, feature 70 "Process connection") has to be ordered with a CSA approval ( ä 76, feature 10
"Approval"). These devices are fitted with a separate plate bearing the registration number 0F10524.5C.
• Specifications for the "T
K
Ambient" and "T
K
Process" are listed in the following tables. These are typical
values. These temperature coefficients apply to silicone oil and the process isolating diaphragm material AISI
316L/1.4435. For other filling oils, this temperature coefficient must be multiplied by the T
K
correction
factor of the corresponding filling oil. For the T
K
correction factors, see also page 59, section "Diaphragm seal
filling oils".
