3.3 Installation instructions
!Note!
• Due to the orientation of the Cerabar M, there may be a shift in the zero point, i.e. when the
container is empty or partially full, the measured value does not display zero. You can correct this
zero point shift ä27, Section 5.1.2 "Function of the operating elements".
• For PMP55, please refer to Section 3.3.2 "Installation instructions for devices with diaphragm
seals – PMP55", ä14.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.

3.3.1 Installation instructions for devices without diaphragm seals –
PMP51, PMC51
!Note!
• If a heated Cerabar M is cooled during the cleaning process (e.g. by cold water), a vacuum
develops for a short time, whereby moisture can penetrate the sensor through the pressure
compensation (1). If this is the case, mount the Cerabar M with the pressure compensation (1)
pointing downwards.
• Keep the pressure compensation and GORE-TEX®filter (1) free from contamination.
• Cerabar M transmitters without diaphragm seals are mounted as per the norms for a manometer
(DIN EN 837-2). We recommend the use of shutoff devices and siphons. The orientation depends
on the measuring application.
• Do not clean or touch process isolating diaphragms 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 Cleanibility).:

PVDF interchangeable threaded boss
!Note!
A maximum torque of 7 Nm (5.16 lbs ft) is permitted for devices with a PVDF interchangeable
threaded boss. 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 the 1/2 NPT thread.

3.3.2 Installation instructions for devices with diaphragm seals –
PMP55
!Note!
• Cerabar M devices with diaphragm seals are screwed in, flanged or clamped, depending on the
type of diaphragm seal.
• A diaphragm seal and the pressure transmitter together form a closed, oil-filled calibrated system.
The fill fluid hole is sealed and may not be opened.
• Do not clean or touch the process isolating diaphragm of the diaphragm seal with hard or pointed
objects.
• Do not remove 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 (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.
• Please observe the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for Cerabar M TI00436P, "Planning instructions for diaphragm seal systems" section.
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 or above the reference temperature
• With a bending radius of 100 mm (3.94 in).

Cerabar M Analog Installation
Endress+Hauser 15
Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter
below the diaphragm seal. This prevents vacuum loading of the diaphragm seal caused by the
presence of filling oil in the capillaries.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustration below left must not be exceeded. The maximum
height difference depends 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 right.
Mounting with temperature isolator
P01-PMx5xxxx-11-xx-xx-xx-008
Endress+Hauser recommends the use of temperature isolators in the event of constant extreme
medium temperatures which lead to the maximum permissible electronics temperature of +85°C
(+185°F) being exceeded. To minimize 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 column in the temperature isolator. You can correct this zero point shift.
