ssible process pres-
sure
Due to the application, a measuring cell with a measuring range higher
than the permissible pressure range of the process fitting may have
been integrated. The permissible process pressure is stated with
"Process pressure" on the type label, see chapter 3.1 "Configuration".
For safety reasons, this range must not be exceeded.
2.8 Fulfillment of NAMUR recommendations
With respect to interference resistance and emitted interference, the
NAMUR recommendation NE 21 is fulfilled.

3.2 Principle of operation
Application area
22441-EN-111006
VEGABAR 14 7
VEGABAR 14 is a pressure transmitter for measurement of gauge
pressure, absolute pressure or vacuum. Measured products are
gases, vapours and liquids.
3 Product description
Func
tional principle
Voltage supply
Packaging
Transport
Transport inspection
®
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.
Two-wire electronics 4 … 20 mA for power supply and measured
value transmission over the same cable.
3.3 Operation
The instrument offers no adjustment options.
3.4 Packaging, transport and storage
The device 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 environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil
is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.
Storage
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration
