4.4 Installation instructions for devices with diaphragm seals (FMD78)

• The diaphragm seal, together with the pressure transmitter, forms a closed, calibrated 

system, which is filled through openings in the diaphragm seal and in the measurement 

system of the pressure transmitter. These openings are sealed and must not be opened.

• Do not remove the protection of the process isolating diaphragm protection until shortly 

before installation.

• When using a mounting bracket, sufficient strain relief must be ensured for the capillaries in 

order to prevent the capillary bending down (bending radius 



100 mm).

• Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause 

zero point shift. The zero point shift can be corrected. 



See Page 20, 4.2.1 "Position of 

operating elements", Page 21, Section 4.2.2 "Function of the operating elements" or Page 30, 

Section 5.1 "Position adjustment".

• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical 

Information for Deltabar S TI00382P, Section "Planning instructions for diaphragm seal 

systems" or at "www.endress.com/applicator".

In order to obtain more precise measurement results and to avoid a defect in the device, mount 

the capillaries as follows:

• vibration-free (in order to avoid additional pressure fluctuations)

• not in the vicinity of heating or cooling lines

• insulate if the ambient temperature is below ore above the reference temperature

• with a bending radius of 

100 mm.

• The ambient temperature and length of both capillaries should be the same when using 

two-sided diaphragm seal systems.

• Two diaphragm seals which are the same (e.g. with regard to diameter, material, etc.) should 

always be used for the negative and positive side (standard delivery).
