Application
The Cerabar T PMP 135 is a pressure
transducer for hygienic applications, e.g.
in the food processing and pharmaceuti-
cal industries. It is designed for measu-
ring absolute and gauge pressures in
gases, vapours, liquids and dust.
•Finely graduated measuring ranges up
to 40 bar or 500 psi.
•Electronic versions:
– Analogue output 4...20 mA
– Switch output
– Approved for use in hazardous areas
Your benefits
This compact pressure transducer
impresses with its well-engineered
construction:
•Flush-mounted process connections
with metal diaphragm.
•Hygienic design as per 3A guidelines.
•Up to 4 times overload resistance and
extremely longterm stable.
•Optional with 3.1.B inspection certifi-
cate.
•Materials in contact with the process
only made of 316L stainless steel with a
surface quality Ra ≤0.8 µm.

Function and system design
Measuring principle PMP 135 with analogue output
The process pressure acting upon the metallic separating diaphragm of the sensor is transmitted
to a resistance bridge via a fluid. The change in the output voltage of the bridge is proportional to
the pressure and can be measured directly.
PMP 135 with switch output
The process pressure acting upon the metallic separating diaphragm of the sensor is transmitted
to a resistance bridge via a fluid. A differential amplifier creates a standard signal from the pres-
sure-proportional change in output voltage of the bridge. A comparator with an adjustable hyste-
resis compares this signal with the pre-set switch point and then activates the transistor output
and the LED display.
Measuring system Cerabar T PMP 135 pressure transducer with
•4…20 mA analogue output.
Power supply, e.g. with RN 221N transmitter power supply unit from Endress+Hauser
•Switch output.
Preferably in connection with programmable logic controllers (PLC). Positive signal at electro-
nics switch output (PNP).
