Quick start

VEGAFLEX 83 • 4 … 20 mA/HART two-wire

2. In the menu item "Medium - Dielectric constant" you can define

the medium type (medium).

3. Carry out the adjustment in the menu items "Min. adjustment" and

"Max. adjustment".

4. A "Linearization" is recommended for all vessels in which the

vessel volume does not increase linearly with the level - e.g. in a

horizontal cylindrical or spherical tank. Activate the appropriate

curve.

5. A "False signal suppression" detects, marks and saves the false

signals so that they are no longer taken into account for level

measurement. We generally recommend a false signal suppres-

sion.

The sensor measures the distance from the sensor (reference plane)

to the product surface.

3 Measuring range (default setting refers to the measuring range in water)

4 Upper dead band (in this area no measurement is possible)

5 Lower dead band (in this area no measurement is possible)

For this adjustment, the distance is entered when the vessel is full

and nearly empty. If these values are not known, an adjustment with

other distances, for example, 10 % and 90 % is also possible. Starting

point for these distance specifications is always the seal surface of

the process fitting.
1. In the menu "Additional settings", menu item "Damping" you can

adjust the requested damping of the output signal.
