Mounting the FTG20 or FMG60 on the FMG60 for empty pipe detection
If the pipe becomes empty as a result of operational processes, the radiation on the detector
side can hit dangerous levels.
• In such instances, the irradiation channel must be closed immediately for reasons of
radiation protection.
• A high local dose rate also causes the detector unit (scintillator and photomultiplier) to age
quickly.
The best way of avoiding such a situation is to mount a second radiometric measuring
system that monitors the radiation intensity. If high radiation levels occur, an alarm is
output and/or the source container is automatically switched off through pneumatic action
for example.
