1Measuring principle
1.1Overview
The VEGABAR 81,82 and 83 can be used universally for the measure-
ment of gases,vapours and liquids.The instrument series is designed for
all applications in industrial measurement engineering.The pressure
transmitters are the ideal solution for special as well as standard applica-
tions.Setup and commissioning is always the same.The VEGABAR 81,
82 and 83 offer maximum reliability and operational safety.
1.2Measuring cell technology
VEGABAR 81
The VEGABAR 81 is equipped with a chemical seal system.It consists of
a process diaphragm as well as an isolating liquid.The process dia-
phragm is available in different materials.
The process pressure acts on the sensor element via the chemical seal
system and an internal stainless steel diaphragm.The process pressure
causes a resistance change which is converted into a corresponding
output signal and outputted as measured value.

3Silicone oil filling
4Process diaphragm
For measuring ranges up to 40 bar,a piezoresistive sensor element with
internal transmission liquid is used,and for measuring ranges 100 bar and
higher,a strain gauge (DMS)sensor element on the back side of the
stainless steel diaphragm (dry)is used.
VEGABAR 82
The sensor element is the CERTEC
®
measuring cell with front-flush,
abrasion resistant ceramic diaphragm.The hydrostatic pressure of the
medium or the process pressure causes a capacitance change in the
measuring cell via the diaphragm.This change is converted into an ap-
propriate output signal.

The CERTEC

measuring cell is also equipped with a temperature sen-
sor.The temperature value can be displayed via the display and adjust-
ment module or processed via the signal output.
VEGABAR 83
The process pressure acts via the process diaphragm to the sensor ele-
ment.The process pressure causes a resistance change which is con-
verted into a corresponding output signal and outputted as measured
value.The process diaphragm is available in different materials.
For measuring ranges up to 40 bar,a piezoresistive sensor element with
internal transmission liquid is used,and for measuring ranges 100 bar and
higher,a strain gauge (DMS)sensor element on the back side of the
stainless steel diaphragm (dry)is used.
With small measuring ranges or higher temperatures,the METEC
®
measuring cell is used.It consists of the ceramic-capacitive CERTEC
®
measuring cell and a special,temperature-compensated chemical seal
system.

6Mounting
Installation position
The instruments function in any installation position.But the installation
position can influence the measurement,depending on the measuring
system.This can be compensated by a position correction.
It is useful to select an installation position you can easily reach for mount-
ing and connecting as well as later retrofitting of an display and adjustment
module.For this purpose,the housing can be rotated by 330°without the
use of any tools.You can also install the indicating and adjustment module
in four different positions (each displaced by 90°).
Mounting examples and measurement setups
The following illustrations show mounting examples and measurement
setups.

7Electronics -4…20 mA-two-wire
Configuration of the electronics
The pluggable electronics is mounted in the electronics compartment of
the instrument and can be exchanged by the user when servicing is re-
quired.The electronics is completely encapsulated to protect against
vibration and moisture.
The terminals for voltage supply as well as the contact pins with I²Cinter-
face for parameter adjustment are located on the upper side of the elec-
tronics.In the double-chamber housing,the terminals are located in the
separate terminal compartment.
Voltage supply
Power supply and current signal are carried on the same two-wire cable.
The operating voltage can differ depending on the instrument version.
You can find the data of the voltage supply in chapter "Technical data"in
the operating instructions manual of the respective instrument.
Provide a reliable separation between the supply circuit and the mains
circuits according to DIN EN 61140 VDE 0140-1.

with a sensor current of 20.5mAor 22 mAin case of fault)
lInfluence of additional instruments in the circuit (see load values in
chapter "Technical data"of the operating instructions of the respective
instrument)
Connection cable
The instrument is connected with standard two-wire cable without screen.
If electromagnetic interference is expected which is above the test values
of EN 61326-1for industrial areas,screened cable should be used.
In the product configurator of VEGABAR,different cable glands are avail-
able.This selection covers all cable diameters in the range of 4…12 mm
(0.16 …0.47 in).
Cable screening and grounding
If screened cable is required,we recommend connecting the cable
screen on both ends to ground potential.In the sensor,the screen must
be connected directly to the internal ground terminal.The ground terminal
on the outside of the housing must be connected to the ground potential
(low impedance).

12 Operation
12.1Overview
The sensors can be adjusted with the following adjustment media:
lWith the display and adjustment module
lWith external display and adjustment unit
lan adjustment software according to FDT/DTM standard,e.g.
PACTware and PC
as well as via systems from other manufacturers,dependent on the signal
output:
lA HART handheld (4…20 mA/HART)
lThe adjustment program AMS (4…20 mA/HART and Foundation
Fieldbus)
lThe adjustment program PDM (Profibus PA)
lAconfiguration tool (Foundation Fieldbus)
The entered parameters are generally saved in the sensor,optionally also
in the display and adjustment module or in the adjustment program.
12.2Display and adjustment module
PLICSCOM
The pluggable display and adjustment module is used for measured value
indication,operation and diagnosis.It is equipped with an illuminated full
dot matrix as well as four keys for adjustment.
Fig.32:Display and adjustment module PLICSCOM
The display and adjustment module is integrated in the respective sensor
housing or in the external display and adjustment unit.After mounting,the
sensor as well as the display and adjustment module are splash-proof
even without housing cover.
12.3PACTware/DTM
As an alternative to the display and adjustment module,the sensor can
also be configured via a Windows PC.To do this,the configuration soft-
ware PACTware and a suitable instrument driver (DTM)according to the
FDT standard are required.The current PACTware version as well as all
available DTMs are compiled in a DTM Collection.The DTMs can also be
integrated into other frame applications according to the FDT standard.
All device DTMs are available as a free-of-charge standard version and as
a full version that must be purchased.In the standard version,all functions
for complete setup are already included.An assistant for simple project
configuration simplifies the adjustment considerably.Saving/printing the
project as well as import/export functions are also part of the standard
version.
In the full version there is also an extended print function for complete
project documentation as well as a save function for measured value and
echo curves.In addition,there is a tank calculation program as well as a
multiviewer for display and analysis of the saved measured value and
echo curves.
Connection of the PC via VEGACONNECT
The interface converter VEGACONNECT is required for connection of the
PC.On the computer side,the connectionis made via USB interface.The
VEGACONNECT is placed instead of the display and adjustment module
