The Power of Know How
Application
The Cerabar T PMP 135 is a pressure

pressure transmitter, engineered for
hygienic processes.
• Flush-mounted process connections
with metal diaphragm

Function and system design
Measuring principle PMP 135 with analog output
The process pressure acting on the metallic separating diaphragm of the sensor is
transmitted to a resistance bridge via a fill fluid. The change in the output voltage of
the bridge is proportional to the pressure and can be measured directly.
PMP 135 with PNP switch output
The process pressure acting on the metallic separating diaphragm of the sensor is
transmitted to a resistance bridge via a fill fluid. A differential amplifier creates a
standard signal from the pressure-proportional change in the output voltage of the
bridge. A comparator with an adjustable hysteresis compares this signal with the
pre-set switch point and then activates the transistor output and LED display.
Cerabar T PMP 135 pressure transmitter with:
• 4 to 20 mA analog output
Power supply, e.g. RN 221N transmitter power supply unit from Endress+Hauser
• Switch output
Preferably in connection with a programmable logic controller (PLC). Positive
signal at electronics switch (PNP).
Measuring system
Input
The measured variable for the Cerabar T PMP 135 pressure transmitter can be
selected as either gauge or absolute pressure.
Measuring ranges up to 500 psi (40 bar) can be selected (refer to Ordering Informa-
tion).
