VEGASON 51P … 53P
Setup
The sensor electronics has two characteris-
tics points (at min. and max.) from which a
linear proportionality between product dis-
tance and the percentage of filling of the
vessel is generated.
Of course, the characteristics points must not
necessarily be at 0 % and 100 %, however
they should be as far apart as possible (e.g.
at 20 % and at 80 %). The difference be-
tween the characteristics points for the min./
max. adjustment should be at least 20 mm
product distance. If the characteristics points
are too close together, the possible measur-
ing error increases. Ideal would be to carry
out the adjustment as shown in the example,
at 0 % and at 100 %.
In the menu "
Instrument data/Parameter ad-
justment/Conditioning/Linearisation“ you can
enter later, if necessary, a correlation be-
tween product distance and % extent of filling
other than linear (see later subitem Linearisa-
tion).
