System Description
3.1
Measuring Principle
The detectors of the DuoSeries are used in industrial measuring systems for meas-
uring the level, density or mass flow in different installation situations. In addition
to the detectors of DuoSeries, additional system components such as transmitters,
radioactive sources and shieldings are required for a complete measuring system.
Usage of these system components is not subject of this operating manual. Please
refer to the individual manuals of the respective system components.
The detectors of the DuoSeries supply measurement signals for further processing
and visualisation of LB 47x or LB 44x transmitters. Each detector is connected to
either an LB 47x/44x transmitter or a 47x slave module.

Scintillator
The DuoSeries detectors differ in their external dimensions and the scintillators
used. Point detectors (CrystalSENS) are equipped either with a 50/50, 40/35 or 25/25
(diameter x length) sodium iodide (NaI) scintillator or a 50/60 polymer scintillator.
Polymer scintillators are used in the rod detectors. Rod detectors (UniSENS) are
available with sensitive lengths of 500 mm, 750 mm, 1000 mm, 1250 mm, 1500 mm
and 2000 mm, TowerSENS detectors with lengths of 3 to 8 m in 1 m components.
The size of the scintillator determines the size of the sensitive area (the area that
is used for the measurement and which is sensitive to gamma radiation). Marking
grooves (Fig. 3) on the detector housing mark size and position of the sensitive
area.
