Notes on Safety
Approved usageThe pressure transmitter Cerabar S is a Foundation Fieldbus device which, depending
upon the version, is used for measuring gauge or absolute pressure. Level measurement
is also possible when a Foundation Fieldbus tool is used.
Installation,
commissioning,
operation
The Cerabar S has been designed to operate safely in accordance with current technical,
safety and EU standards. If installed incorrectly or used for applications for which it is
not intended, however, it is possible that application-related dangers may arise, e.g.
product overflow due to incorrect installation or calibration. For this reason, the instrument
must be installed, connected, operated and maintained to the instructions in this manual
personnel must be authorised and suitably qualiflied. The manual must have been read
and understood, and the instructions followed. Modifications and repairs to the device
are permissible only when they are expressly approved in the manual.
Explosion hazardous
area
If the device is to be installed in an explosion hazardous area, then the specifications in
the certificate as well as all national and local regulations must be observed. The
instrument can be delivered with the certificates listed in the table below. The certificate
can be identified from the first letter of the order code stamped on the nameplate.
•Ensure that all personnel are suitably qualified.
•Observe the specifications in the certificate as well as national and local regulations.
•Take special care with regard to the grounding of the bus cable screening.
Recommendations are to be found in the FF specification or IEC 79–14.

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 transmitterif the
density ρof the liquid is known.

1.1 Measuring system
Measuring point In the simplest case, the complete measuring point comprises:
•Cerabar S transmitter with Foundation Fieldbus protocol
•Network Configuration Tool, e.g. National Instruments Fieldmanager
Number of transmitters The maximum number of transmitters on a bus segment is determined by their current
consumption, the required bus length and if installed the power of the link.
Normally, however:
•10 Cerabar S for EEx ia applications
•max. 32 Cerabar S for non-hazardous application
can be operated on a bus segment. Cerabar S consumes max. 11.5 mA per device.
Refer also to the FF specification or IEC 61158-2 or to the Internet address
"http://www.fieldbus.org".

2 Installation
This section describes the mechanical installation of Cerabar S with and without
diaphragm seals.
2.1 Mounting instructions without diaphragm seal
Cerabar S
without diaphragm seal
– PMC 731
– PMP 731
The Cerabar S without diaphragm seal is mounted in the same way as a manometer. 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 pigtail above the tapping
point.
The pigtail reduces the temperature in
front of the diaphragm to almost
ambient temperature. The pigtail must
be filled with water 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 PVC 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 and internal diaphragm.
The adapter can be screwed on or welded in.
A seal is enclosed appropriate to the material used and version.
