Berthold noncontact weighing systems are used for the precise determination of mass flow of solid matter on a variety of conveyor systems. For many such conveyor systems, radiometric weighing is the only suitable method for mass flow measurement. Berthold systems are easily installed, and can even be used for massflow determination during free fall (see our application note, Free Fall Bulk Flow Meter).

Applications
|
The Principle of Measurement Measurement is based upon the attenuation of gamma radiation by matter. A rod-shaped gamma source is installed below the massflow in a lockable shielding with collimated radiation opening. A scintillation detector above the massflow detects the attenuated radiation and provides a signal dependent on area weight. The area weight and conveyor speed form the basis for the calculation of massflow.
Advantages
Detector and Evaluation Technology Berthold instruments feature precise and efficient scintillation crystals to measure the gamma radiation and send a digital signal to the evaluation electronics. High crystal sensitivity allows low source activities. Automatic source decay compensation and automatic drift compensation result in a high long-term repeatability of + 0.1%.
Microprocessor-based evaluation electronics allow easy calibration and integration into your existing or planned process control system. Single-point calibration and a current loop output signal proportional to massflow make Berthold units a trouble-free solution for your weighing task.
