VEGAFLEX 82 • 4 … 20 mA/HART - four-wire

To damp process-dependent measured value fluctuations, set an

integration time of 0 … 999 s in this menu item.

The default setting is a damping of 0 s.

A linearization is necessary for all vessels in which the vessel volume

does not increase linearly with the level - e.g. a horizontal cylindri-

cal or spherical tank, when the indication or output of the volume is

required. Corresponding linearization curves are preprogrammed

for these vessels. They represent the correlation between the level

percentage and vessel volume.
The linearization applies to the measured value indication and the

current output. By activating the appropriate curve, the volume per-

centage of the vessel is displayed correctly. If the volume should not

be displayed in percent but e.g. in l or kg, a scaling can be also set in

the menu item "Display".

Caution:

If a linearization curve is selected, the measuring signal is no longer

linearly proportional to the level. This must be taken into consideration

by the user, particularly when setting the switching point on the limit

signal indicator.

Since the scaling is very comprehensive, the scaling of the level value

was divided into two menu items.
In menu item "Level 1" you define the scaling size and the scaling unit

for the level value on the display, e.g. volume in l.
