Principle of operation
Application area
VEGABAR S 14 is a pressure transmitter for
measurement of gauge pressure, absolute pres-
sure or vacuum. Measured products are gases,
vapours and liquids.
Functional principle
The sensor element is the CERTEC
® measuring
cell with rugged ceramic diaphragm. The process
pressure causes a capacitance change in the
measuring cell via the ceramic diaphragm. This
change is converted into an appropriate output
signal and outputted as measured value.
Voltage supply
Two-wire electronics 4 … 20 mA for power supply
and measured value transmission over the same
cable.

General instructions
Suitability for the process conditions
Make sure that all parts of the instrument exposed
to the process, in particular the sensor element,
process seal and process fitting, are suitable for
the existing process conditions. These include
above all the process pressure, process temper-
ature as well as the chemical properties of the
medium.
You can find the specifications in chapter "Tech-
nical data"
or on the type label.
