VEGABAR 82 • Slave sensor for electronic dierential pressure
46332-EN-160212
1.6 Permissible process pressure
The permissible process pressure is specied on the type label with
"Process pressure", see chapter "Conguration". 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 certied according
to DIN EN ISO 14001.
Please help us fulll 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 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.

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 fullled:

VEGABAR 82 • Slave sensor for electronic dierential pressure
46332-EN-160212
• Conguration, Master sensor suitable for electronic dierential
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:

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
