Device for determining the mass per unit volume of an elementary volume of material |
摘要 |
The invention provides a device for delivering an indication about the mass per unit volume of the contents of an elementary volume, comprising a directional X or gamma radiation source and a directional photoelectronic photon detector, and wherein said source and/or said detector are mounted for rotation on a common support, about an axis orthogonal to the plane defined by the axis of the radiation beam emitted by said source and by the axis of the reception channel of said detector, and means are provided for moving said common support in a direction orthogonal to the axis of rotation of said source and/or of said detector.
