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.

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.

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

supply units.
The supply voltage and the current signal are carried on the same twowire connection cable.
Provide a reliable separation between the supply circuit and the mains
circuits according to DIN VDE 0106 part 101.
VEGA power supply units VEGATRENN 149AEx, VEGASTAB 690,
VEGADIS 371 as well as all VEGAMETs meet this requirement. When
using one of these instruments, protection class III is ensured for
VEGABAR 14.
Keep in mind the following additional factors that influence the
operating voltage:
l Output voltage of the power supply unit can be lower under
l Influence of additional instruments in the circuit (see load values in
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas, screened cable should be
used.
Use cable with round cross-section. A cable outer diameter of 5 … 9 mm
(0.2 … 0.35 in) ensures the seal effect of the cable gland. If you are
using cable with a different diameter or cross-section, exchange the
seal or use a suitable cable gland.

Connect the cable screen on both ends to ground potential.
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed, but the protective effect against high frequency interference signals remains.

5 Connecting to power supply
Warning:
Within galvan
protection there are considerable potential differences. Considerably
equalisation currents can be caused via the cable scrren when the
screen is earthed on both ends. To avoid this, the cable screen must
only connected to ground potential on one side of the switching
cabinet in such applications. The cable screen must not be connected
to the internal ground terminal in the sensor and the outer ground
terminal on the housing not to the potential equalisation!
Information:
The
metal parts of the instrument (antenna, transmitter, concentric
tube, etc.) are conductive connected with the inner and outer ground
terminal on the housing. This connection exists either directly metallic
or with instruments with external electronics via the screen of the
special connection cable. You can find specifications to the potential
connections within the instrument in chapter "Technical data".

5.4 Switch-on phase
After connecting VEGABAR 14 to power supply or after a voltage
recurrence, the instrument carries out a self-check:
l Internal check of the electronics
l 4 … 20 mA output jumps to the fault signal 22 mA
Then VEGABAR 14 delivers a current of 4 … 20 mA to the cable. The
value corresponds to the actual level as well as to settings already
carried out, e.g. the factory setting.

7.2 Remove interferences
The operator of the system is responsible for taking suitable measures
to rectify faults.
VEGABAR 14 offers maximum reliability. Nevertheless, faults can
occur during operation. These may be caused by the following, e.g.:
l Sensor
l Process
l Voltage supply
l Signal processing
The first measure to be taken is to check the output signal. In many
cases, the causes can be determined this way and the faults rectified.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.
The hotline is available to you 7 days a week round-the-clock. Since
we offer this service world-wide, the support is only available in the
English language. The service is free of charge, only the standard
telephone costs will be charged.
