Hence the sensor electronics has two char-
acteristics points (MIN and MAX), out of
which a linear proportionality between prod-
uct distance and the percentage filling of a
vessel is generated.
However the characteristics points must not
be at 0 % and 100 % but the difference
should be as large as possible (e.g. at 20 %
and at 80 %). The min. product distance of
the characteristics point for min./max. adjust-
ment should be 50 mm. When the character-
istics points are too close together, the possi-
ble meas. error increases.
It is hence suitable to carry out the adjust-
ment at 0 % and at 100 %.
In the menu " Instrument data/Parameter ad-
justment/Conditioning/Linearisation" you can
adjust later another linear dependence be-
tween product distance and the percentage
filling degree (see later subpoint
linearisation).
Conditioning
• Click in the menu window " Instrument data
parameter adjustment" to "Conditioning".
The menu window " Conditioning" opens.
• Click to "Scaling".
In the menu " Scaling" you enter the actual
0 % and 100 %-values of the parameter and
their unit. Hence you inform the sensor, e.g.
that at 0 % filling there are 45,5 litres and at
100 % filling 1200 litres in the vessel.
The sensor indication then displays with empty
vessel 45,5 litres (0 %) and at full vessel
1200 litres (100 %).
