Nuclear humidity detector

Kurzfassung

A Slovak research institute has developed a special apparatus used for continuous measurement of humidity of loose material transported by conveyor belts. They are open for license and/or joint venture.

Details

The apparatus developed by a Slovak research institute is used for continuous measurement of humidity of loose material transported by conveyor belts. Characteristics of apparatus, description and function: Fast neutrons decelerated by hydrogen atoms create a cloud of slow neutrons, which induces radiation inside a detecting probe. GM (Geiger-Mueller) tubes register this radiation. The impulses from tubes are electronically processed into an electric signal proportionally to the humidity of material.Technical data: Range of measurement: 0% - 100%, accuracy of measurement: 0.2% of measured value. Radiator and detecting probe (4 GM tubes) are mounted on the same board, which is hanging over the conveyor belt during operation. The evaluation unit can be installed in the control room.Innovative Aspects:Radiator and detecting probe (4 GM tubes) are mounted on the same board, which is hanging over the conveyor belt during operation. The evaluation unit can be installed in the control room. The impulses from tubes are electronically processed into an electric signal proportionally to the humidity of material. It is a very quick method for humidity measurement.
