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.

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.

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.

2.2 Mounting instructions with diaphragm seal
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 diaphragm 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 instrument should only be turned
by the diaphragm seal and not by 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 when the continuous
extreme product temperatures cause the
maximum permissible ambient
temperature to exceed +85 °C.
•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.

2.5 Connection
General notes Cerabar S is loop-powered transmitter (type 111) with Foundation Fieldbus output. Note
the following before connecting up:
•Turn off the power before connecting up.
•Connect the external ground terminal of the transmitter to the plant grounding
system before connecting up.
Power The Cerabar S has the following power requirements:
I = 10.5 mA ± 1 mA
Non-Ex: U = 9...32 VDC
Ex: U = 9…24 VDC
Cable Twisted, shielded pairs must be used. The cable specifications can be taken from the
FF specification or IEC 61158-2. The following have been found suitable:
Non-Ex-area: Siemens 6XV1 830-5BH10,
Belden 3076F,
Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL.
Ex-area: Siemens 6XV1 830-5AH10,
Belden 3076F,
Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL
Screening General information on wiring can be found at the Fieldbus Foundation website:
www.fieldbus.org. For maximum protection against electromagnetic interference, e.g.
when the bus is operating near frequency converters, it is recommened that high integrity
potential bonding be provided between the housing and the cable screening.
The external ground terminal on the transmitter must be connected to ground.
The continuity of the cable screening between tapping points must be ensured.
The screening must be grounded at each end of the cable.
If there are large differences in potential between grounding points, the grounding should
run via a capicitor that is suitable for high frequency use
(e.g. ceramic 10 nF/250 V~).

3.2 Hardware settings
A DIP-switch in the connection compartment of the Cerabar S controls allows the
write protection and simulation functions to be set via hardware.
The default settings of the switches are as follows:
WP OFF: write protection via hardware is disabled
SIM ON: simulation is enabled (= allowed in configuration tool).
Device identification
Foundation Fieldbus identifies the device by its identification code and automatically
allocates an appropriate field address. There is no separate hardware switch for this
purpose.
When the device has been integrated into the network, see Chapter 3.3, it appears as
follows in the bus tree:
E+H_CERABAR_S_XXXXXXXX
A click on the name reveals the device tag, device ID and node address. The device
ID is made up of the following components:
Device_ID = 452B481007-XXXXXXXX
whereby: 452B48 = ID code for Endress+Hauser
1007 = ID code for Cerabar S
XXXXXXXX = Device serial number, as printed on the name plate
A right-hand mouse click on the name opens up a menu from which the PD_TAG and
NODE_ADDRESS can be changed.

If the resource block is out of service, then all blocks within the device
(resource) are forced into the same status.
RS_STATE Indicates the state of the resource block application state machine
On-line: block in AUTO mode
Standby: block in OOS mode
WRITE_LOCK Indicates the status of DIP-switch WP.
RESTART Allows a manual restart:
UNINITIALISED: no status
RUN: normal operational status
RESOURCE: resets the resource block parameters
DEFAULTS: Resets all Foundation Fieldbus parameters within the device,
but not the manufacturer specific parameters.
PROCESSOR: make a warm start of the processor
BLOCK_ERROR Shows error status of software and hardware components
Out-of-Service: the block is in OOS mode
Simulation active: shows the setting of DIP-switch WP
BLOCK_ALM Shows any configuration, hardware, connection and system problems in
the block. The cause of the alert is to be seen in the subcode field.
