tional installation standards as well as the valid safety regulations and
accident prevention rules must be observed by the user.
For safety and warranty reasons, any invasive work on the device
beyond that described in the operating instructions manual may be
carried out only by personnel authorised by the manufacturer. Arbi-
trary conversions or modications are explicitly forbidden. For safety
reasons, only the accessory specied by the manufacturer must be
used.
To avoid any danger, the safety approval markings and safety tips on

1 For your safety
VEGABAR 82 • Secondary sensor for electronic dierential pressure
46332-EN-220624
The EU conformity declaration can be found on our homepage.
Due to the design of its process ttings, the device does not subject
of EU pressure device directive if it is operated at process pressures
≤ 200 bar.
1.6 Environmental instructions
Protection of the environment is one of our most important duties.
That is why we have introduced an environment management system
with the goal of continuously improving company environmental pro-
tection. The environment management system is certied according
to DIN EN ISO 14001.
Please help us full this obligation by observing the environmental
instructions in this manual:
• Chapter " Packaging, transport and storage"
• Chapter " Disposal"

3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter " Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.

With the following instruments a blind plug is installed instead of the
lter element:
• Instruments in protection IP66/IP68 (1 bar) - ventilation via capillar-
ies in non-detachable cable
• Instruments with absolute pressure
3.3 Combination Primary/Secondary sensor
In principle, any sensor combination within the instrument series is
allowed. The following requirements must be fullled:
• Conguration of the sensor suitable for electronic dierential pres-
sure
• Pressure type is identical for both sensors, i.e. relative pressure/
relative pressure or absolute pressure/absolute pressure

VEGABAR 82 • Secondary sensor for electronic dierential pressure
46332-EN-220624
• Primary Device measures the higher pressure
• Measurement setup as shown in the following chapters
The measuring range of each sensor is selected such that it ts the
measuring loop. For this, the max. recommended turn down must be
noted. See chapter " Technical data". It is absolutely necessary the
the measuring ranges of Primary and Secondary Device correspond.
Measurement result = Measured value of Primary (total pres-
sure) - measured value of Secondary (static pressure)
Depending on the application, individual combinations can result, see
following examples:
Data
Application: Level measurement
Medium: Water
Vessel height: 12 m, hydrostatic pressure = 12 m x 1000 kg/m3x
9.81 m/s2 = 117.7 kPa = 1.18 bar
Superimposed pressure: 1 bar
Total pressure: 1.18 bar + 1 bar = 2.18 bar
Instrument selection
Nominal measuring range Primary: 2.5 bar
Nominal measuring range Secondary: 1 bar
Turn Down: 2.5 bar/1.18 bar = 2.1 : 1
Data
Application: Level measurement
Medium: Water
Vessel height: 500 mm, hydrostatic pressure = 0.50 m x 1000 kg/m3x
9.81 m/s2 = 4.9 kPa = 0.049 bar
Superimposed pressure: 350 mbar = 0.35 bar
Total pressure: 0.049 bar + 0.35 bar = 0.399 bar
Instrument selection
Nominal measuring range Primary: 0.4 bar
Nominal measuring range Secondary: 0.4 bar
Turn Down: 0.4 bar /0.049 bar = 8.2 : 1
Data
Application: Dierential pressure measurement
Medium: Gas
Static pressure: 0.8 bar
Dierential pressure on orice: 50 mbar = 0.050 bar
Total pressure: 0.8 bar + 0.05 bar = 0.85 bar
Instrument selection
Nominal measuring range Primary: 1 bar
Nominal measuring range Secondary: 1 bar

4 Connecting to power supply
4.1 Connecting
The connection to the Primary Device is carried out through spring-
loaded terminals in the respective housing. For this, use the supplied,
confectioned cable. Solid cores as well as exible cores with cable
end sleeves are inserted directly into the terminal openings.
In case of exible cores without end sleeves, press the terminal from
above with a small screwdriver, the terminal opening is then free.
When the screwdriver is released, the terminal closes again.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
You can nd further information on the max. wire cross-section under
" Technical data - Electromechanical data".
Proceed as follows:
1. Unscrew the housing lid
2. Loosen compression nut of the cable gland and remove blind
plug
3. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) insulation from the individual wires or use supplied
connection cable
4. Insert the cable into the sensor through the cable entry
Fig. 3: Connection steps 5 and 6
5. Insert the wire ends into the terminals according to the wiring plan
6. Check the hold of the wires in the terminals by lightly pulling on
them

7. Connect the shielding to the internal ground terminal, connect the
external ground terminal to potential equalisation
8. Tighten the compression nut of the cable entry gland. The seal
ring must completely encircle the cable
9. Unscrew the blind plug on the Primary, screw in the supplied
cable gland
10. Connection cable to Primary, see steps 3 to 8
11. Screw the housing lid back on
The electrical connection is nished.
