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 or using the handheld operating
terminals for HART or INTENSOR.
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. Pay
attention to the technical data on the nameplate.
Explosion hazardous
area
The measuring system used in the explosion hazardous area must comply with all existing
national standards. The instrument can be supplied with the following certificates as listed
in the table. A separate Ex-documentation is enclosed with the device and is an integral
part of this documentation. The installation regulations, connection values and Safety
Instructions listed in this document must be observed. 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.

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
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.

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
•supply voltage for non-hazardous area: 11.5…45 V DC,
EEx ia: 11.5…30 V DC, EEx d and EEx d[ia]: 13…30 V DC, EEx nA: 11.5…36 V DC
For electronic versions with HART or INTENSOR 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 (HART protocol)
•the Commulog VU 260 Z handheld terminal (INTENSOR protocol)
