2.7 Fulfilling NAMUR recom
mendations
VEGABAR 75 fulfills the following NAMUR recommendations:
l NE 21 (interference resistane and emitted interference)
l NE 43 (signal level for failure
information)
l NE 53 (compatibility sensor and indicating/adjustment
components)
VEGA instruments are generally upward and downward
compatible:
l Sensor
software to DTM VEGABAR 75 HART
l DTM
VEGABAR 75 for adjustment software PACTware™
The parameter adjustment of the basic sensor functions is
independent of the software version. The range of available
functions depends on the respective software version of the
individual components.
The software version of VEGABAR 75 HART can be read out
via PACTware™.

Product description
28433-EN-070718
3.2 Principle of operation
VEGABAR 75 is a pressure transmitter for use in the chemical,
food processing and pharmaceutical industry. Thanks to the
high protection class IP 68/IP 69K it is particularly suitable for
use in humid environment. Depending on the version, it is used
for level, gauge pressure, absolute pressure or vacuum
measurements. Measured products are gases, vapours and
liquids, also with higher temperatures.
The METEC
®
measuring cell is the measuring unit. It consists
of the ceramic-capacitive CERTEC
®
measuring cell and a
special, temperature-compensating isolating system.
The hydrostatic pressure of the product or the process
pressure causes a capacitance change in the measuring cell
via the metal process diaphragm and the isolating liquid. This
change is converted into a corresponding output signal.

5 CERTEC®measuring cell
The CERTEC
®
measuring cell is also equipped with a
temperature sensor. The temperature value can be processed
via the signal output.

The supply voltage range can differ depending on the
instrument version.
The data for power supply are stated in chapter "Technical
data" in the "Supplement".
3.3 Operation
VEGABAR 75 4 … 20 mA/HART can be adjusted with different
adjustment media:
l with external adjustment/indication VEGADIS 12
l an adjustment software according to FDT/DTM standard,
e.g. PACTware™ and PC
l with a HART handheld
The
kind
of adjustment and the adjustment options depend on
the selected adjustment component. The entered parameters
are generally saved in the respecitive sensor, when adjusting
with PACTware™ and PC optionally also in the PC.
3.4 Packaging, transport and storage
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 environ-
ment-friendly, 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.
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:

4.1 General instructions
Make sure that
the wetted parts of VEGABAR 75, especially
the seal and process fitting, are suitable for the existing
process conditions such as pressure, temperature etc. as well
as the chemical properties of the medium.
You can find the specifications in chapter "Technical data" in
the "Supplement".
Caution:
After removal of the diaphragm protective cover, the diaphragm must not be pressed.
l The connection cable has a capillary for atmospheric
pressure compensation
à Lead the
cable end into a dry space or into a suitable
terminal housing.
Information:
VEGA recommends the breather housing VEGABOX 02 or the
indication/adjustment VEGADIS 12. Both contain terminals
and a ventilation filter for pressure compensation. For
mounting outdoors, a suitable protective cover is available.
Higher process temperatures often mean also higher ambient
temperatures. Make sure that the upper temperature limits
stated in chapter "Technical data" for the environment of the
electronics housing and connection cable are not exceeded.
