DEVICE FOR X-RAY AND RADIOMETRIC ANALYSIS OF COMPOSITION OF PULPS AND SOLUTIONS Russian patent published in 2004 - IPC

FIELD: analysis of composition and density of liquid media in technological flow. SUBSTANCE: given device comprises two parts. One part has technological hole of conical form with geometrical vertex located in point of radiation recording and ratio of diameter of base to height of cone exceeding 4 and is set in wall of vessel with analyzed medium. Second part has hole securing passage of flux of primary radiation, is positioned outside of vessel. Spacer displaying ratio of diameter of hole to thickness of spacer over 10 is placed between parts. Diameter of hole in spacer is not less than diameter of technological hole in first part, hole in spacer is covered on two sides with layers of material showing low absorption properties for X-ray or radio nuclide radiation. Sensor recording break of layer of material contacting pulp or solution is arranged between layers of material. Signal from sensor is sent to switching -off unit and detector recording radiation is suspended from springs inside second part. EFFECT: raised accuracy of analysis. 2 dwg
