1 Introduction
ApplicationsThe Cerabar S pressure transmitter measures the pressure of gases, steam/vapour and
liquids and can be used in all areas of chemical and process engineering.
Operating principle
Ceramic sensor
The system pressure acts directly on the
rugged ceramic diaphragm of the pressure
sensor deflecting it by a maximum of 0.025
mm. A pressure-proportional change in the
capacitance is measured by the electrodes
on the ceramic substrate and diaphragm.
The measuring range is determined by the
thickness of the ceramic diaphragm.
Metal sensor
The process pressure deflects the
separating diaphragm with a filling liquid
transmitting the pressure to a resistance
bridge. The bridge output voltage, which is
proportional to pressure, is then measured
and processed.
Level measurement
The hydrostatic pressure of a column of
liquid enables its level to be measured
continuously by a pressure transmitter if the
density ρof the liquid is known.

Cerabar S
without diaphragm seal
– PMC 731
– PMP 731
The Cerabar S without diaphragm seal is mounted in the same way as a manometer
(DIN EN 839-2). The use of shut-off valves and pigtails is recommended. Its position
depends upon the application.
•Measurement in gases:
Mount the shut-off valve above the
tapping point so that condensate can
run back into the process.
•Measurement in steam:
Mount with a below the tapping point.
The pigtail reduces the temperature in
front of the diaphragm to almost
ambient temperature. The pigtail must
be filled with fill fluid before start-up.

•Measurement in liquids:
Mount on the shut-off valve below the
tapping point or at the same height.
PVDF adapter For instruments with PVDF adapter, a maximum torque of 7 Nm 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 ½ NPT thread.
Mounting the PMP 731 The PMP 731 with metallic sensor is available in the following versions:
•with flush-mounted diaphragm or
•with adapter (screwed on or welded in) and internal diaphragm.
A seal is enclosed appropriate to the material used and version.
Note!
The diaphragm of the Cerabar S must not be pressed in or cleaned with pointed or hard
objects.

2.2 Mounting instructions with diaphragm seal (PMC 631, PMP 635)
Cerabar S
with diaphragm seal
– PMC 635
– PMP 635
The Cerabar S with diaphragm seal is
screwed in, flanged or clamped,
depending on the type of diaphragm seal.
•The protective cap of the diaphragm
seal should only be removed just before
mounting in order to protect the
diaphragm.
•The membrane of the diaphragm seal of
the Cerabar S must not be pressed in or
cleaned with pointed or hard objects.
•The diaphragm seal and the pressure
sensor together form a closed and
calibrated system which is filled with
filling fluid through a hole in the upper
part. The following rules should be
observed:
–This hole is sealed and not to be
opened.
–The device may only be rotated on
the surface provided on the
diaphragm seal instrument and not on
the housing.
Level measurementFor level measurement the Cerabar S must
always be installed below the lowest
measuring point.
•The instrument should not be installed
within the flow of material, in the outlet
of the tank or at a place in the tank
where pressure pulses from agitator
blades may occur.
•Calibration and function testing are
easier to carry out if the Cerabar S is
mounted downstream from a shut-off
valve.
Mounting with
temperature spacers
The use of temperature spacers is
recommended for continuous extreme
product temperatures.
•Note when mounting that the
temperature spacer increases the
maximum height by 100 mm.
•Due to the hydrostatic column in the
temperature spacer, the increased
height also causes a zero point shift of
approx. 10 mbar.
See Chapter 5.1, pages 26 and 27 for
information concerning position
calibration (display only) or zero-point
correction.

3 Operation
3.1 On-site operation
Operating elements Four keys, which allow the lower and upper range-values to be set, are available for
on-site operation. The key functions are listed in the table below.
Display module The local display module (optional) has two display modes:
•Display in measurement mode: This is shown as standard
•Display in calibration mode: This is shown after pressing one of the keys +Z, –Z, +S
or –S once. Returns automatically to measurement mode after 2 seconds.
Key functions
+Z increases the lower range-value (zero) by +1 digit *
–Z decreases the lower range-value (zero) by –1 digit *
+S increases the upper range-value (span) by +1 digit *
–S decreases the upper range-value (span) by –1 digit *
Key combinations (Press keys simultaneously)
Keys Function
Calibration
+Z and –Z the acting pressure is taken as lower range-value (4 mA)
+S and –S the acting pressure is taken as upper range-value (20 mA)
Bias pressure
2 times +Z and +S the acting pressure is taken as bias pressure**
1 time +Z and +S the current bias pressure** is shown
2 times –Z and –S the current bias pressure** is deleted
Securing the measuring point by locking/unlocking
+Z and –S Locking the measuring point
–Z and +S Unlocking the measuring point
The procedure for commissioning the measuring point with local operation is described
in Chapter 4.

Key functions
* Note: Pressing once activates
the display, only by pressing
again does the display begin to
count. When first pressing the
key the values slowly change
and then increase in speed.
** If the display indicates process
pressure zero not as zero after
calibrating lower range-value
(depending on position) you can
correct the display value to zero
by adopting a bias pressure. The
position calibration using a bias
pressure does not affect the
current output.

3.4 Operation with Commuwin II
When operating the Commuwin II display and operating program, the Cerabar S is set
and and operated either using:
•Matrix mode or
•Graphic mode.
The appropriate server (e.g. HART or ZA 672) must therefore be activated. A description
of the operating program Commuwin II is to be found in Operating Instructions BA 124F.
Note!
You can obtain the current device description (DD) either from your local
Endress+Hauser Sales Center or via the Internet (http://www.endress.com →Products
→Product Portfolio →Process Solutions →Commuwin II →Updates/Downloads).
Matrix mode
(Menu Device)
You can access the extended functions of the Cerabar S, such as level measurement,
using the "Device/Parameter Matrix" menu.
•Each row is allocated to a particular function.
•Each field sets or displays one parameter.
Enter the setting parameters in the appropriate fields and confirm by pressing ↵.
Graphic mode
(Menu Device)
Commuwin II offers graphic examples of certain configuration procedures which you can
access from the "Device/Graphics" menu. There you can directly modify parameters and
confirm by pressing ↵.
