The detector head assembly measures the gamma radiation emitted from the AGT400 source head. It contains an ionization chamber that creates an electrical flow based on the amount of gamma rays collected. The AGT400 Thickness Gauge uses this information to determine the thickness of material passing through the beam.
This unit contains the following:
- ION-445 4.5″ Ion Chamber
- CBA-110 Pre-Amp Circuit Board
- ICD-110 Field Effect Transistor (FET)
