VEGABAR 82 • Slave sensor for electronic dierential pressure
46332-EN-160212
1.6 Permissible process pressure
The permissible process pressure is specied on the type label with
"Process pressure", see chapter "Conguration". For safety reasons,
this range may not be exceeded. This applies even if a measuring cell
with a measuring range (order-related) higher than the permissible
pressure range of the process tting is installed.
1.7 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 fulll this obligation by observing the environmental
instructions in this manual:
• Chapter "Packaging, transport and storage"
• Chapter "Disposal"

3 Mounting
3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connecting to power
supply")
• Tighten the cable gland
• When mounting horizontally, turn the housing so that the cable
gland points downward
• Loop the connection cable downward in front of the cable gland
This applies mainly to outdoor installations, in areas where humidity is
expected (e.g. through cleaning processes) and on cooled or heated
vessels.
3.2 Ventilation and pressure compensation
The lter element is mounted into the electronics housing. It has the
following functions:
• Ventilation of the electronics housing
• Atmospheric pressure compensation (with relative pressure meas-
uring ranges)
→ Turn the housing so that the lter element points downward after
the instrument is installed. This provides better protection against
buildup.

4 Filter element
With the following instruments a blind plug is installed instead of the
lter element:
• Instruments in protection IP 66/IP 68 (1 bar) - ventilation via capil-
laries in non-detachable cable
• Instruments with absolute pressure
3.3 Combination Master - Slave
In principle, any sensor combination within the VEGABAR 80 series is
allowed. The following requirements must be fullled:

VEGABAR 82 • Slave sensor for electronic dierential pressure
46332-EN-160212
• Conguration, Master sensor suitable for electronic dierential
pressure
• Pressure type is identical for both sensors, i.e. relative pressure/
relative pressure or absolute pressure/absolute pressure
• Master sensor 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 Master and Slave correspond.
Measurement result = Measured value of Master (total pres-
sure) - measured value of Slave (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 Master: 2.5 bar
Nominal measuring range Slave: 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 Master: 0.4 bar
Nominal measuring range Slave: 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 bar = 0.050 bar
Total pressure: 0.8 bar bar + 0.05 bar = 0.85 bar

The measuring result (level, pressure dierence) as well as measured
value Slave (static or superimposed pressure) are outputted by the
sensor. Depending on the instrument version, output as 4 … 20 mA
signal or digitally via HART, Probus PA or Foundation Fieldbus.

4 Connecting to power supply
4.1 Connecting
The connection to the Master sensor 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 screen 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 Master, screw in the supplied cable
gland
10. Connection cable to Master, see steps 3 to 8
11. Screw the housing lid back on
The electrical connection is nished.
