Technical Information
Cerabar M PMC41/45, PMP41/45/46/48
Process pressure measurement
Pressure transmitter with ceramic and metal sensors
Overload-resistant and function-monitored
With Analog, HART or PROFIBUS PA Electronics
Application
The Cerabar M pressure transmitters measure
overpressure and absolute pressure in gases, steam,
liquids and dusts. Thanks to the modular instrument
concept, Cerabar M suits all areas of process engineering.
All hygienic connections, threaded connections and
flanges (also as diaphragm seals) are available as process
connections.

Ceramic sensor
➀ Air pressure (overpressure sensors)
➁ Ceramic carrier
➂ Electrodes
➃ Ceramic diaphragm
Ceramic measuring diaphragm used for PMC41 and PMC45 (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 (max. 60 bar)
• Thanks to 99.9% high-purity ceramic (Ceraphire
– Extremely high chemical stability
– Less relaxation
– High mechanical stability
• Suitable for vacuums
• Very suitable for hygienic processes as the ceramic material Al

Metal measuring diaphragm used for PMP41, PMP45, PMP46 and PMP48
PMP41 and PMP45
The operating pressure deflects the separating diaphragm and a fill fluid transfers the pressure to a resistance
measuring bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is
measured and processed further.
Advantages:
• Can be used with process pressures up to 400 bar
• High long-term stability
• Guaranteed overload resistance up to 4 times the nominal pressure (max. 600 bar)
• Compact solution even for small hygienic connections
PMP46 and PMP48
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 in the bridge output
voltage is measured and processed further.
Advantages:
• Can be used with process pressures up to 400 bar
• High long-term stability
• Guaranteed overload resistance up to 4 times the nominal pressure (max. 600 bar)

Onsite display (optional) Analog display for devices with analog electronics
A plug-in liquid crystal display (LCD), with a bar graph for showing the current (30 segments), is used as the
display unit. The display can be rotated in 90° stages.
Functions:
• Bar graph to indicate the measured value from 0 to 100%. This corresponds to a signal current of 4 to 20 mA.
• The scale flashes to indicate signal undershoot (current < 3.8 mA).
• The bar graph and scale flash to indicate signal overshoot (current > 20.5 mA).

Digital display for devices with 4 to 20 mA HART or PROFIBUS PA electronics
A plug-in digital display, with a 4-digit pressure display and bar graph (28 segments), is used as the display unit.
The display can be rotated in 90° stages.
Functions:
• 4-digit pressure display
• Bar graph
– 4 to 20 mA HART: the bar graph displays the current value (4 to 20 mA) belonging to the pressure value.
– PROFIBUS PA: the bar graph displays the current pressure value in relation to the set measuring range.
• Easy diagnosis by displaying an error code

Operating conditions (installation)
• The position-dependent zero point shift can be corrected directly at the device by means of a key or a
potentiometer. Diaphragm seals also shift the zero point, depending on the installation position
(→ see also Page 65, "Installation instructions, diaphragm seal systems" section).
• Endress+Hauser offers a mounting bracket for installing on pipes. → See also Page 26, "Wall and pipemounting" section.
• The onsite display can be rotated in 90° stages.
• Devices with EHEDG approval: these devices must be installed in accordance with the Hygienic Equipment
Design Criteria to meet the requirements of EHEDG.
• For PMP46, PMP48: see Page 65, "Installation instructions, diaphragm seal system" section.
Cerabar M devices without diaphragm seals are mounted as per the norms for a manometer (DIN EN 839-2).
We recommend the use of shutoff devices and siphons. The orientation depends on the measuring application.
Pressure measurement in gases
• Mount Cerabar M with shutoff device above the tapping point so that any condensate can flow into the
process.
Mounting with temperature isolator
Pressure measurement in steam
• Mount Cerabar M with siphon above the tapping point.
The siphon reduces the temperature to almost ambient temperature.
• Fill the siphon with liquid before commissioning.
Pressure measurement in liquids
• Mount Cerabar M with shutoff device below or at the same level as the tapping point.
• Do not mount the device at the following positions:
In the fill curtain, in the tank outlet or at a point in the container which could be affected by pressure pulses
from an agitator or a pump.
Endress+Hauser recommends the use of temperature isolators in the event of constant extreme fluid
temperatures which lead to the maximum permissible electronics temperature of +85°C (+185°F) being
exceeded.
Depending on the filling oil used, Cerabar M devices with temperature isolators can be used for maximum
temperatures of up to 260°C (+500°F). → For the temperature application limits of filling oils, see Page 60,
"Diaphragm seal filling oil" section.
To minimize the influence of rising heat, Endress+Hauser recommends the device be mounted horizontally or
with the housing pointing downwards.
The additional installation height also brings about a zero point shift of maximum 21 mbar due to the
hydrostatic column in the temperature isolator. You can correct this zero point shift.
