12.9 Plate-Plate Sensor Systems

The plate-plate sensor system is determined by the plate ra-
dius and the variable distance between the stationary and
the movable plate. This distance should not be smaller than
0.5 mm and not larger than 3 mm as other measurement er-
rors, depending on the substance, could be experienced.
Geometry:
The distance of the plate should be at least three times larger
than the largest particle contained in the substance. he
plate-plate sensor system must be very carefully filled in or-
der to minimize measurement errors. Both, too low a filling
and too high a filling will cause measurement errors.
