VEGABAR 81 • HART and accumulator pack
45026-EN-131107
VEGABAR 81 can be used for process pressure and level measure-
ment. Default setting is process pressure measurement. The mode
can be changed in this adjustment menu.
The VEGABAR 81 in conjunction with a slave sensor can be used for
flow, differential pressure, density and interface measurement. The
default setting is differential pressure measurement. Switchover is
carried out in the adjustment menu.
Depending on the selected application, different subchapters in the
following adjustment steps are important. There you can find the
individual adjustment steps.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
In this menu item, the adjustment units of the instrument are deter-
mined. The selection determines the displayed unit in the menu items
"Min. adjustment (zero)" and "Max. adjustment (span)".
Unit of measurement:
If the level should be adjusted in a height unit, the density of the me-
dium must also be entered later during the adjustment.
In addition, the temperature unit of the instrument is specified. The se-
lection determines the displayed unit in the menu items "Peak value,
measuring cell temperature", "Peak value, electronics temperature"
as well as "HART variables".
Temperature unit:
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Especially with chemical seal systems, the installation position of the
instrument can shift (offset) the measured value. Position correction
compensates this offset. In the process, the actual measured value
is taken over automatically. With relative pressure measuring cells a
manual offset can also be carried out.
