Software History
Note!
Second generation Cerabar S PROFIBUS-PA devices with 3.0 profiles are cyclical
downwards compatible with the first generation Cerabar S PROFIBUS-PA devices
with 2.0 profiles, i.e. first generation devices can be replaced with second generation
devices.
However, to use the additional functions of second generation devices with
3.0 profiles, such as cyclical reading of two additional values, the PLC must be
configured with the GSD (EH3x1501.gsd or EH3_1501.gsd).
If the additional functions of the 3.0 profile are not required, the PLC configuration with
the first generation GSD (EH__1501.gsd) can be kept.

Notes on Safety
Approved usageThe Cerabar S is a pressure transmitter used for measuring gauge or absolute pressure,
depending on the version. You can display the measured pressure value as a level value
using the Commuwin II operating and display program.
Mounting,
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 according to the instructions in
this manual: personnel must be authorised and suitably qualified. 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.
Please pay particular attention to the technical data on the nameplate. pmax (maximum
allowed pressure) is specified on the nameplate. The value refers to a reference
temperature of 20°C (68°F) or 100°F for ANSI flanges.
•Test pressure (over pressure limit OPL) = pmax
•The pressure values permitted at higher temperatures can be found in the following
standards: EN 1092-1: 2001 Tab. 18; ASME B 16.5a – 1998 Tab. 2-2.2 F316;
ASME B 16.5a – 1998 Tab. 2.3.8 N10276; JIS B2201
Explosion hazardous
areas
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,
see e.g. IEC 60079-14.

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 transmitter if the
density ρof the liquid is known.

Cerabar S PROFIBUS-PA 1 Introduction

1.1 Measuring system
Measuring point In the simplest case, the measuring point comprises:
•Cerabar S with PROFIBUS-PA protocol
•PLC or personal computer with an operating program e.g. Commuwin II
•Segment coupler
•PROFIBUS-PA terminating resistor
Number of transmitters The maximum number of transmitter on one bus segment is determined by their
consumption, the power of the bus coupler and the required bus length, see Operating
Instructions BA 198F/00/en. Normally however:
•max. 10 Cerabar S for hazardous area applications
•max. 32 Cerabar S for non-hazardous area applications
can be operated on one bus segment. Cerabar S consumes max. 11 mA per device.
For further information, see Operating Instructions BA 198F "PROFIBUS-DP/-PA:
Guidelines for planning and commissioning", the PNO Guidelines or under the Internet
address http://www.PROFIBUS.com and for operation in hazardous ia areas: EN 50020
(FISCO model).

This Chapter describes:
•the mechanical installation of Cerabar S with and without diaphragm seals
•the electrical connection
2.1 Mounting instructions without diaphragm seal (PMC/PMP 731)
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 pigtail 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.
