2.2 Principle of operation
Area of application
VEGABAR S 16 is a pressure transmitter for
measurement of gauge pressure, absolute pres-
sure or vacuum. Measured products are gases,
vapours and liquids.
Functional principle
Sensor element is the CERTEC
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.
Supply
Two-wire electronics 4 ... 20 mA for power supply
and measured value transmission on the same
cable.
2.3 Packaging, transport and storage
Packaging
Your instrument was protected by packaging
during transport. Its capacity to handle normal
loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of
environment-friendly, recyclable cardboard. For
special versions, PE foam or PE foil is also used.
Dispose of the packaging material via specialised
recycling companies.
Transport

of the notes on the transport packaging. Non-
observance of these instructions can cause dam-
age to the device.
Transport inspection
The delivery must be checked for completeness
and possible transit damage immediately at re-
ceipt. Ascertained transit damage or concealed
