Notes on Safety
Approved usage The 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 or using the handheld operating
terminals for HART.
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 overspill by incorrect installation or adjustment. For this reason, the instrument
must be installed, connected, operated and maintained by personnel that are authorised
by the user of the facility and who are 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.
Explosion hazardous
area The measuring system used in the explosion hazardous area must comply with all existing
national standards. The certificates are designated by the first letter of the order code
on the nameplate (see table below).
•Ensure that technical personnel are adequately trained.
•All measurement and safety regulations which apply to the measuring point are to
be observed.

Note!
A note highlights actions or procedures which, if not performed correctly, may indirectly affect
operation or may lead to an instrument response which is not planned.
Caution!
Caution highlights actions or procedures which, if not performed correctly, may lead to
personal injury or incorrect functioning of the instrument.
Warning!
A warning highlights actions or procedures which, if not performed correctly, will lead to
personal injury, a safety hazard or destruction of the instrument.
Device certified for use in explosion hazardous area
If the device has this symbol embossed on its name plate it can be installed in an explosion
hazardous area.
Explosion hazardous area
Symbol used in drawings to indicate explosion hazardous areas.
– Devices located in and wiring entering areas with the designation "explosion hazardous
areas" must conform with the stated type of protection.
Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion hazardous areas.
– Devices located in safe areas still require a certificate if their outputs run into explosion
hazardous areas.
Direct voltage
A terminal to which or from which a direct current or voltage may be applied or supplied.
Alternating voltage
A terminal to which or from which an alternating (sine-wave) current or voltage may be
applied or supplied.
Grounded terminal
A grounded terminal, which as far as the operator is concerned, is already grounded by
means of an earth grounding system.
Protective grounding (earth) terminal
A terminal which must be connected to earth ground prior to making any other connection to
the equipment.
Equipotential connection (earth bonding)
A connection made to the plant grounding system which may be of type e.g. neutral star or
equipotential line according to national or company practice.

1 Introduction
Applications The 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
Metal sensor
The process pressure deflects the
separating diaphragm and a fill fluid
transmitts 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.

1.1 Measuring system
The complete measuring system consists of
•Cerabar S pressure transmitter with 4…20 mA signal output
•optional four-character pressure display
•power supply 11.5…45 V DC
For electronic versions with HART protocol, a digital communication signal is
superimposed on the signal current and is used for remote calibration.
These instruments have additional functions also to measure level.
Operation can be carried out using:
•the Commuwin II operating program
•the Universal HART Communicator DXR 275 handheld (HART protocol)

2 Installation
This chapter describes:
•the mechanical installation of Cerabar S
•the electrical connection
2.1 Mounting instructions PMP 71 K
The Cerabar S 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.
Mounting the PMP 71 KThe PMP 71 K with metallic sensor is available in the following version:
•with adapter (welded in) and internal diaphragm.
Note!
The diaphragm of the Cerabar S must not be pressed in or cleaned with pointed or hard
objects.
