VEGAFLEX 82 • 4 … 20 mA/HART - four-wire
41830-EN-130314
Since the HART variables are very extensive, the indication was
divided into two menu items.
In the menu "HART variables 1" you can have the first HART value PV
(primary value) and the second HART value SV (secondary value) of
the sensor displayed.
The values cannot be changed in the display and adjustment module.
To change these values, you have to use the adjustment software
PACTware.
In the menu "HART variables 2" you can have the third HART value
TV (third value) and the fourth HART value QV (quarter value) of the
sensor displayed.
The values cannot be changed in the display and adjustment module.
To change these values, you have to use the adjustment software
PACTware.
The following circumstances cause interfering reflections and can
influence the measurement:
•
High sockets
•
Vessel installations such as struts
•
Deflectors, etc.
Note:
A false signal suppression detects, marks and saves these false sig-
nals so that they are no longer taken into account for level measure-
ment.
This should be done with the lowest possible level so that all potential
interfering reflections can be detected.
Proceed as follows:
Enter the actual distance from the sensor to the product surface.
All interfering signals in this section are detected by the sensor and
stored.
