The Model 500 Nuclear Belt Scale /Density Meter is a state-of-the-art device that uses gamma radiation to measure the weight of bulk materials on conveyor belts—accurately and without contact.
The scale operates on the principle of gamma energy attenuation, which varies with material density. A sealed radioactive source and detector are mounted across the conveyor. The radiation passes through the material and is measured below the belt. An industrial computer processes these signals and displays real-time weight data.
Readings are taken every 3 seconds and averaged over 60 seconds. Output is available via analog connections or direct database access for seamless integration into plant control systems.
