1 Introduction
Applications
The Cerabar S pressure transmitter measures the pressure of gases, steam/vapour and
liquids and can be used in all areas of chemical and process engineering.
Operating principle
Metal sensor
The
process
pressure
deflects
the
separating diaphragm and a fill fluid
transmitts the pressure to a resistance
bridge. The bridge output voltage, which is
proportional to pressure, is then measured
and processed.
Level measurement
The hydrostatic pressure of a column of
liquid enables its level to be measured
continuously by a pressure transmitter if the
density
ρ
of the liquid is known.
