Technical Information

Cerabar S PMC71, PMP71/72/75

Pressure transmitter
with ceramic and metal sensors
Overload-resistant and function-monitored; Communication via
HART, PROFIBUS PA or FOUNDATION Fieldbus

Application

The Cerabar S pressure transmitter is used for the
following measuring tasks:

• Absolute pressure and gauge pressure in gases, steams
or liquids in all areas of process engineering and
process measurement technology

• Level, volume or mass measurement in liquids

• High process temperature
– without diaphragm seals up to 150°C (302°F)
– with typical diaphragm seals up to 350°C (662°F)

• High pressure up to 700 bar

• International usage thanks to a wide range of approvals

Your benefits

• Very good reproducibility and long-term stability

• High reference accuracy: up to ±0.075%,
as PLATINUM version: ±0.05%

• Turn down 100:1, higher on request

• Meets PED (Pressure Equipment Directive)

• Used for process pressure monitoring up to SIL 2,
certified according to IEC 61508 by TÜV SÜD

•HistoROM

• Function-monitored from the measuring cell to the
electronics

• Continuous modularity for differential pressure and
pressure (Deltabar S – Cerabar S), e.g.
– replaceable display
– universal electronic

• Quick commissioning thanks to quick setup menu

• Easy and safe menu-guided operation on-site,
via 4...20 mA with HART, via PROFIBUS PA or
via FOUNDATION Fieldbus

• Extensive diagnostic functions

• Device versions in conformity with ASME-BPE

Ceramic measuring diaphragm used for PMC71 (Ceraphire

The ceramic sensor is a dry sensor, i.e. the process pressure acts directly on the robust ceramic diaphragm and
deflects it. A pressure-dependent change in capacitance is measured at the electrodes of the ceramic carrier and
the diaphragm. The measuring range is determined by the thickness of the ceramic diaphragm.

Advantages:

• Guaranteed overload resistance up to 40 times the nominal pressure

• Thanks to highly-pure 99.9% ceramic (Ceraphire
– extremely high resistance compared to Alloy
–less relaxation
– high mechanical stability

• Suitable for vacuums

• Second process barrier (Secondary Containment) for enhanced integrity

• Process temperature up to 150°C (302°F)

P01-PMP7xxxx-03-xx-xx-xx-000

Metallic measuring diaphragm used for PMP71 and PMP75

PMP71

The operating pressure deflects the separating diaphragm and a fill fluid transfers the pressure to a resistance
measuring bridge (semi-conductor technology). The pressure-dependent change of the bridge output voltage
is measured and processed further.

Advantages:

• Can be used with process pressures up to 700 bar

• High long-term stability

• Guaranteed overload resistance up to 4 times the nominal pressure (PMP71)

• Second process barrier (Secondary Containment) for enhanced integrity

• Significantly less thermal effect compared to diaphragm seal systems

PMP75

The operating pressure acts on the diaphragm of the diaphragm seal and is transferred to the separating
diaphragm of the sensor by a diaphragm seal fill fluid. The separating diaphragm is deflected and a fill fluid
transfers the pressure to a resistance measuring bridge. The pressure-dependent change of the bridge output
voltage is measured and processed further.

Advantages:

• Can be used with process pressures from 400 mbar to 400 bar

• High long-term stability

• Guaranteed overload resistance up to 4 times the nominal pressure

• Second process barrier (Secondary Containment) for enhanced integrity

Human interface

On-site display (optional) A 4-line liquid crystal display (LCD) is used for display and operation. The on-site display shows measured

values, dialog text as well as fault and notice messages in plain text, thereby supporting the user in every stage
of operation.

4...20 mA HART

Functions:

• 8-digit measured value display including sign and decimal point, bargraph for current display

• Simple and complete menu guidance thanks to separation of the parameters into three levels

• Each parameter is given a 3-digit ID number for easy navigation.

• Option for configuring the display according to individual requirements and desires, such as language,
alternating display, display of other measured values such as sensor temperature, contrast setting

• Comprehensive diagnostic functions (fault and warning message, peak-hold indicators, etc.)

• Rapid and safe commissioning with the Quick Setup menus

Operating elements With regard to T14 housings, the operating keys are located either outside the device under the protection cap

or inside on the electronic insert. In T17 housings, the operating keys are always located inside on the
electronic insert.
In addition, devices with an on-site display and a 4 to 20 mA HART electronic insert have operating keys on
the on-site display.

The operating keys located externally on the device work on the Hall sensor principle. As a result, no additional
openings are required in the device. This guarantees:

• Complete protection against environmental influences such as moisture and contamination

• Simple operation without any tools

•No wear.

• Quick and safe commissioning of the same measuring points by copying the configuration data of one
transmitter to another transmitter

• Reliable process monitoring thanks to cyclical recording of pressure and sensor temperature measured values

• Simple diagnosis by recording diverse events such as alarms, configuration changes, counters for measuring
range undershoot and overshoot for pressure and temperature as well as user limit overshoot and undershoot
for pressure and temperature etc.

• Analysis and graphic evaluation of the events and process parameters via ToF Tool (contained in scope of
supply)

Reading cycle • HART commands: on average 3 to 4 per second

• PROFIBUS PA:

– max.: 100/s
– typical value: 20/s

– acyclic:

– typical value: 10/s

• FOUNDATION Fieldbus:
– cyclic: up to 5/s, dependent on the number and type of function blocks used in a closed-control loop

Cycle time (Update time) PROFIBUS PA

• The cycle time in a bus segment in cyclic data communication depends on the number of devices, on the
segment coupler used and on the internal PLC cycle time.

• The minimum cycle time is approx. 20 ms per device.

Response time • PROFIBUS PA:

– cyclic: approx. 10 ms per request
– acyclic: < 50 ms

• FOUNDATION Fieldbus:

Test

Taking 4...20 mA test signal

A 4...20 mA signal may be measured via the positive and test terminal without interrupting the measurement.
The minimum supply voltage of the device can be reduced by simply changing the position of the jumper. As
a result, operation is also possible with lower voltage sources. Observe the position of the jumper in accordance
with the following table.

Jumper position for test signal Description

Test

– Taking 4...20 mA test signal via plus and test terminal:

possible. (Thus, the output current can be measured without

interruption via the diode.)
– Delivery status
– minimum supply voltage: 11.5 V DC

Supply voltage Note!

• When using the measuring device in hazardous areas, installation must comply with the corresponding
national standards and regulations and the Safety Instructions or Installation or Control Drawings.

• All explosion protection data are given in separate documentation which is available upon request. The Ex
documentation is supplied as standard with all devices approved for use in explosion hazardous areas. → See
also page 82 ff sections "Safety Instructions" and "Installation/Control Drawings".
