•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 shutoff device.
4.4.2Installation instructions for devices with diaphragm seals –
PMP75
•Cerabar S devices with diaphragm seals are screwed in, flanged or clamped, depending on
the type of diaphragm seal.
•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.
•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.
Improper handling!
Damage to the device!
‣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.
‣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 (3.94 in)).
‣Please observe the application limits of the diaphragm seal filling oil as detailed in the
Technical Information for Cerabar S TI00383P, "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).
‣Do not use the capillaries as a carrying aid for the diaphragm seals!

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 fill fluid in the capillary.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustrations below must not be exceeded.
A0020472
Fig. 10: Installation above the lower diaphragm seal
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 vessel), see illustration
below:

Mounting with temperature isolator
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. Depending on the filling oil used,
diaphragm seal systems with temperature isolators can be used for maximum temperatures
of up to +400 °C (+752 °F). For the temperature application limits, see technical
Information, "Diaphragm seal filling oils" section. 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 maximum zero
point shift of 21 mbar (0.315 psi) due to the hydrostatic column in the temperature isolator.
You can correct this zero point shift at the device.

Information on filling
The diaphragm seal must be filled as soon as it has been welded on.
•After welded 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, at the zero point the device display should not
exceed 10% of the full scale value of the cell measuring range. 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 must then be calibrated to the process measuring range as
described in the Operating Instructions.

4.4.9Closing the housing cover
Devices with EPDM cover seal - transmitter leakiness!
Mineral-based, animal-based or vegetable-based lubricants cause the EPDM cover seal to
swell and the transmitter to become leaky.
‣The thread is coated at the factory and therefore does not require any lubrication.
The housing cover can no longer be closed.
Damaged thread!
‣When closing the housing cover, please ensure that the thread of the cover and housing
are free from dirt, e.g. sand.If you feel any resistance when closing the cover, check the
thread on both again to ensure that they are free from dirt.
