Abstract

Dispositif de mesure d'un poids par unité de surface de matériaux en combinaison. La combinaison de matériaux constituée par un carton 1, un revêtement en CaCO3 , 2, et un revêtement de surface en kaolin 3 est irradiée par un rayonnement provenant d'une source à radioisotope 4; les rayons X émis par cette source excitent le rayonnement à rayons X secondaire du calcium présent dans la couche 2, dont l'intensité est mesurée au moyen des détecteurs 6 et 7 des deux côtés du carton 1; le détecteur 5 est en outre utilisé pour mesurer l'absorption du rayonnement primaire provenant de la source 4 dans la combinaison carton-revêtement Dispositif de mesure de poids par unité de surface d'une combinaison de matériaux sur une machine de revêtement de papier ou de carton.Device for measuring a weight per unit area of materials in combination. The combination of materials consisting of a cardboard 1, a CaCO3 coating, 2, and a kaolin surface coating 3 is irradiated with radiation from a radioisotope source 4; the X-rays emitted by this source excite the secondary X-ray radiation of the calcium present in the layer 2, the intensity of which is measured by means of the detectors 6 and 7 on both sides of the carton 1; detector 5 is further used to measure the absorption of primary radiation from source 4 in the cardboard-coating combination Device for measuring the weight per unit area of a combination of materials on a paper coating machine or cardboard.
