VEGAPULS 42, 44 and 45 – VBUS 61
Adjustment with the PC on the signal conditioning instrument
Here the calculated linearisation curve is
again outputted. The volume information
under "
Linearised" now corresponds no
longer to the calculated volume of the tank
calculation program. Why?
In the menu " Scaling" (Instrument data/Condi-
tioning/Scaling) you entered that at 0 % filling
there are 45 liters in the tank and at 100 %
filling 1200 liters. The geometry of the calcu-
lated cylindrical tank is reduced to a size that
has a volume of only 1200 liters. The
linearisation curve of the calculated vessel is
therefore modified to fit the volume data you
entered in the menu "
Scaling".
If the true content of the calculated vessel
should be outputted, the volume that was
determined in the tank calculation program
must be entered in the menu "Scaling".
The sensor then outputs the actual filling
volume by means of the adjusted vessel
dimensions.
• Quit the menu with
"OK".
• Confirm with
"OK" and your individual
linearisation curve is saved in the sensor.
Again in the menu window " Conditioning", you
can enter with the menu item " Integration time"
a measured value integration. This is recom-
mended for agitated product surfaces, to
prevent the measured value indication and
output from changing constantly.
As a standard feature, an integration time of
0 seconds is preset.
• Quit the menu with
"OK"., you are again in
the menu window " Instrument data param-
eter adjustment".
• Quit the menu window with
"OK".
