1.4.2 Rod Detector Arrangement
Fig. 1-6 shows an arrangement with rod-shaped detector (Uni-
SENS) and point source. The length of the rod detector determines
the length of the measuring range; for larger measuring ranges it is
possible to work with several UniSENS rod detectors or one Tower-
SENS.
For unfavorable measuring geometries one can also work with two
point sources. As the characteristic curve shows, the measuring
geometry results in non-linearities which are compensated for by a
correction line that is adjusted to the measuring site and stored in
the evaluation electronics.
The required tag-specific calculations will be provided by
BERTHOLD TECHNOLOGIES.
