3.3.2 Installation instructions for devices with diaphragm seals –
PMP75
!
Note!
• The Cerabar S with diaphragm seal is screwed in, flanged or clamped, depending on the type of
diaphragm seal.
• The diaphragm seal and the pressure sensor together form a closed an calibrated system which is
filled with filling fluid through a hole in the upper part. This hole is sealed and not to be opened.
• Do not clean or touch diaphragm seals with hard or pointed objects.
• Do not remove membrane 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 also Page 45, Section 6.3 "Position
adjustment".
• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for Cerabar S TI383P, Section "Planning instructions for diaphragm seal systems". →
See also Page 2, "Overview documentation".
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 in the event of colder or warmer ambient conditions
• with a bending radius of ≥100 mm.
Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter
underneath the diaphragm seal. A vacuum load of the diaphragm seal caused by the presence of
filling oil in the capillaries is hereby prevented.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustration below on the left must not be exceeded. The
maximum height difference is dependent on the density of the filling oil and the smallest ever
pressure that is permitted to occur at the diaphragm seal (empty container), see illustration below,
on the right.

Mounting with temperature separator
P01-PMx7xxxx-11-xx-xx-xx-005
Endress+Hauser recommends the use of temperature separators in the event of constant extreme
fluid temperatures which lead to the maximum permissible electronics temperature of +85°C
(+185°F) being exceeded.
The additional installation height also brings about a zero point shift of approx. 21 mbar due to the
hydrostatic columns in the temperature separator. You can correct this zero point shift. →See also

Taking 4...20 mA test signal
A 4...20 mA signal may be measured via the positive and test terminal without interrupting the
measurement. The minimum supply voltage of the device can be reduced by simply changing the
position of the jumper. As a result, operation is also possible with lower voltage sources. To keep
the measured error below 0.1%, the current measuring device should display an internal resistance
of < 0.7 Ω. Observe the position of the jumper in accordance with the following table.
4.2.2 Cable specification
• Endress+Hauser recommends using twisted, screened two-wire cables.
• Terminals for wire cross-sections 0.5...2.5 mm
