3.2 Installation conditions
3.2.1 Dimensions
For dimensions, please refer to "Mechanical construction" section in TI00383P.
3.3 Installation instructions
!Note!
• Due to the orientation of the Cerabar S, there may be a shift in the measured value, i.e. when the
container is empty, the measured value does not display zero. You may correct this zero point
shift either directly on the device using the "E"-key or by remote operation. See
ä26, "Function of the operating elements – on-site display not connected" or
ä41, "Position adjustment".
• For PMP75, please refer to ä12, "Installation instructions for devices with diaphragm seals –

• To ensure optimal readability of the on-site display, it is possible to rotate the housing up to 380°.
ä18, "Rotating the housing".
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
ä15, "Wall and pipe-mounting (optional)".
3.3.1 Installation instructions for devices without diaphragm seals –
PMP71, PMC71
!Note!
• If a heated Cerabar S is cooled during the cleaning (e.g. by cold water), a vacuum develops for a
short time, whereby water can penetrate the sensor through the pressure compensation (1).

Installation Cerabar S PMC71, PMP71, PMP75 with 4 to 20 mA HART
10 Endress+Hauser
If this is the case, mount the sensor with the pressure compensation (1) pointing downwards.
• Keep the pressure compensation and GORE-TEX®filter (1) free from contaminations and water.
• Cerabar S without diaphragm seal are mounted as per the norms for a manometer
(DIN EN 837-2). We recommend the use of shut-off devices and siphons. The orientation
depends on the measuring application.
• Do not clean or touch process isolating diaphragm seals with hard or pointed objects.
• The device must be installed as follows in order to comply with the cleanability requirements of
the ASME-BPE (Part SD Cleanability):

• Use siphons for pressure measurement in steam. The siphon reduces the temperature to almost
ambient temperature. Preferably mount the Cerabar S with the siphon below the tapping point.
Advantages:
– defined water column only causes minimal/negligible measured errors
– only minimal/negligible thermal effects on the device
Mounting above the tapping point is also possible. Pay attention to the maximum permitted
ambient temperature of the transmitter!
• Fill the siphon with liquid before commissioning.

• Mount Cerabar S below the lowest measuring point.
• Do not mount the device at the following positions:
In the fill flow, in the tank outlet or at a point in the container which could be affected by pressure
pulses from an agitator.
• Do not mount the device in the suction area of a pump.
• The calibration and functional test can be carried out more easily if you mount the device after a
shut-off device.
PVDF adapter
!Note!
For instruments with PVDF adapter, a maximum torque of 7 Nm (5.16 lbf ft) is permitted.
The thread connection may become loose at high temperatures and pressures. This means that the
integrity of the thread must be checked regularly and may need to be tightened using the torque
given above. Teflon tape is recommended for sealing with the 1/2 NPT thread.
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 process isolating diaphragm of the diaphragm seals with hard or pointed
objects.
• Do not remove the protection of the process isolating diaphragm 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 (3.94 in)).
• 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. ä41, "Position adjustment".
• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for Cerabar S TI00383P, Section "Planning instructions for diaphragm seal systems".
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 (3.94 in).

Cerabar S PMC71, PMP71, PMP75 with 4 to 20 mA HART Installation
Endress+Hauser 13
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 isolator
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. To minimise the influence of rising heat, Endress+Hauser recommends
the device be mounted horizontally or with the housing pointing downwards. The additional
installation height also brings about a zero point shift of approx. 21 mbar (0.315 psi) due to the
hydrostatic columns in the temperature isolator. You can correct this zero point shift. See also
ä26, "Function of the operating elements – on-site display not connected" or
ä41, "Position adjustment".
