Application / Function
Application The Cerabar T PMP135
is a pressure transmitter designed for
measuring absolute and gauge
pressures in hygienic applications
within in the food processing and
pharmaceutical industries.
Application exampleFunction 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.
Cerabar T pressure transducer
with 4 to 20 mA output and
auxiliary power supply, such as
RN221N.
