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).:

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.

including, 40 bar (600 psi) sensors: the total welding depth of the fillet weld is 1 mm (0.04 in) with
an outer diameter of 16 mm (0.63 in). Welding is performed according to the WIG method.

Information on filling

The diaphragm seal must be filled as soon as it has been welded on.

• After welding into the process connection, the sensor assembly must be properly filled with a

filling oil and sealed gas-tight with a sealing ball and lock screw.
Once the diaphragm seal has been filled, the device display should not exceed 10% of the full scale
value of the cell measuring range at the zero point. The internal pressure of the diaphragm seal
must be corrected accordingly.

• Adjustment / calibration:

– The device is operational once it has been fully assembled.
– Perform a reset. The device then has to be calibrated to the process measuring range as

explained in the Operating Instructions.

7 Maintenance

Keep the pressure compensation and GORE-TEX® filter (1) free from contamination.

P01-xMx5xxxx-17-xx-xx-xx-000.

7.1 Cleaning instructions

Endress+Hauser offer flushing rings as accessories to clean process isolating diaphragms without
taking the transmitters out of the process.
For further information please contact your local Endress+Hauser Sales Center.

7.1.1 Cerabar M PMP55

We recommend you perform CIP (cleaning in place (hot water)) before SIP (sterilization in place
(steam)) for pipe diaphragm seals. A frequent use of sterilization in place (SIP) will increase the stress
on the process isolating diaphragm. Under unfavorable circumstances in the long term view we
cannot exclude that a frequent temperature change could lead to a material fatigue of the process
isolating diaphragm and possibly to a leakage.

7.2 Exterior cleaning

Please note the following points when cleaning the device:

• The cleaning agents used should not corrode the surface and the seals.

• Mechanical damage to the diaphragm, e.g. due to sharp objects, must be avoided.

• Observe the degree of protection of the device. See the nameplate if necessary ( ? 6 ff).
