Pressure Transmitter
cerabar M PMP 46
cerabar M PMP 48
Overload resistant pressure transmitter with
diaphragm seal and analogue, Smart or
PROFIBUS-PA electronics
PMP 48
Flange
Applications
The Cerabar M transmitter measures the
gauge and absolute pressure of gases,
vapours and liquids and can be used in
all areas of industry.
Installation and process conditions often
make the use of diaphragm seals
necessary. Endress+Hauser offers you
the following:
• PMP 46: diaphragm seals for hygienic
applications
• PMP 48: diaphragm seals with
threaded boss, separator, flange or
flange with extension

The Power of Know How
PMP 46
Clamp
Features and Benefits
• Accuracy
− Linearity better than 0.2% of set span
− Adjustable measuring range with
TD 10:1
− Long-term stability better than 0.1%
• Piezoresistive metal sensor with metal
diaphragm for measuring ranges up to
400 bar (6000 psi).
• Electronics
− Analogue: cost effective version with
short response time especially for
fast processes
− Smart: intelligent with versatile
operating procedures via HART
protocol
− PROFIBUS-PA: tried and tested for
digital communications
• Housing
With its stainless steel housing and no
dead volume, the Cerabar M fulfils all
the special hygienic requirements of
the food and pharmaceutical
industries. The polyester-epoxy
coated aluminium housing has proven
itself well in the process industry.
• Process connections
All customary thread versions,
hygienic connections and flanges
available.

  • Page 6: Operating Principle

    Piezoresistive Sensor with Operating Principle Diaphragm Seal The process pressure acting on the diaphragm of the diaphragm seal is transmitted to the metallic separating diaphragm of the sensor by the filling fluid of the diaphragm seal. The separating diaphragm is deflected and the fluid transmits the pressure to a resistance bridge.

    (see page 12). Mounting with Temperature Spacer Endress+Hauser recommends the use of a temperature spacer when extreme media temperatures (from approx. 150°C/302°F) continually cause the ambient temperature to exceed the permissible limit of +85°C (+185°F).
  • Page 11 Mounting with Capillary Tubing Installation To protect from high temperatures (max. (Continuation) 350°C/+662°F media temperature), moisture, vibration, or where the mounting point is not easily accessible, the housing of the Cerabar M can be mounted with a capillary tubing away from the measuring point.
