VEGACAP 67 • Two-wire
31317-EN-200929
With the potentiometer on the controller and the measuring range
selection switch (1) on VEGACAP 67 you can change the sensitivity
of the probe to the electrical properties of the product and the condi-
tions in the vessel. This is necessary so that the level switch can also
reliably detect products e.g. with very low or very high dielectric figure.
range 1: 0 … 20 pF
Range 2: 0 … 85 pF
Range 3: 0 … 450 pF

The adjustment of the switching point is only possible in installed
condition.
Standing capacitances in a vessel can influence the measurement.
We therefore recommend to carry out a compensation of these stand-
ing capacitances before the adjustment.
1. Make sure that the probe is correctly mounted and connected.
2. Make sure that the probe is uncovered.
