VEGABAR 86 • Secondary Device for electronic differential pressure
48048-EN-220817
VEGABAR 86 always measures pressure independently of the pro-
cess variable selected in the menu item "
Application
". To output the
selected process variable correctly, an allocation of the output signal
to 0 % and 100 % must be carried out (adjustment).
With the application "
Interface
" the hydrostatic pressure at min. and
max. height of the interface is entered for adjustment. See the follow-
ing example:

Fig. 22: Parameter adjustment example "Min./max. adjustment, interface
measurement"
1 Min. interface = 0 % correspond to 0.0 mbar
2 Max. interface = 100 % correspond to 490.5 mbar

If these values are not known, an adjustment with interface layers of
for example 10 % and 90 % is also possible. By means of these set-
tings, the layer of the actual interface is then calculated.
The real product level during the adjustment is not important,
because the adjustment is always carried out without changing the
product level. These settings can be made ahead of time without the
instrument having to be installed.
Note:
If the adjustment ranges are exceeded, the entered value will not be
accepted. Editing can be interrupted with
[ESC]
or corrected to a
value within the adjustment ranges.
Proceed as follows:
1. Select the menu item "
Setup
" with
[->]
and confirm with
[OK]
.
Now select with
[->]
the menu item "
Adjustment
", then "
Min.
adjustment
" and confirm with
[OK]
.
