ach product has diﬀerent reﬂective properties. In addition, there are

various interfering factors which have to be taken into account:
agitated product surfaces and foam generation (with liquids); dust
generation, material cones and echoes from the vessel wall (with
solids). To adapt the sensor to these diﬀerent conditions, you should
ﬁ

rst select in this menu item under "Medium" either "Liquid" or "Solid".

ith coax versions, this menu item must be set to "Liquid".

epending on the dielectric ﬁgure (dielectri value or ε

measured

products can have a diﬀerent reﬂective property. Therefore an
additional selection possibility is available.

nder "Sensitivity" you can select "Standard (DK ≥ 2)" or "Increased

sensitivity (DK < 2)".

hrough this the sensor is optimally adapted to the product and

measurement reliability, particularly in products with bad reﬂective
properties, is considerably increased.

o suppress ﬂuctuations in the measured value display, e. g. caused

by an agitated product surface, a damping can be set. This time can
be between 0 and 999 seconds. Keep in mind that the reaction time of
the entire measurement will then be longer and the sensor will react to
measured value changes with a delay. In general, a period of a few
seconds is suﬃcient to smooth the measured value display.
