Method and device for taking and measuring a sample of a material of a process, for example, a granulation process. The material to be measured is allowed to accumulate as free fall into the measuring chamber (7) of a measuring means, such as a cuvette (3), the desired measurement is performed through the wall of the measuring means (3) and the measuring means (3) is emptied by means of a pulse of a turbulence-causing, gaseous substance, directed from the bottom upwards in the measuring chamber (7). The measuring means (3) of the device is divided by a partition (6) into two parts, so that the gas pulse is directed to near to the bottom of the measuring means on one side (5) and from the bottom upwards on the other side (7) of the wall (6).

L'invention porte sur un procédé et sur un dispositif pour prélever et mesurer un échantillon d'un matériau d'un traitement, par exemple un traitement de granulation. On laisse le matériau devant être mesuré s'accumuler en chute libre dans la chambre de mesure (7) de moyens de mesure, telle qu'une cuvette (3), la mesure désirée est effectuée à travers la paroi des moyens de mesure (3) et les moyens de mesure (3) sont vidés à l'aide d'une impulsion d'une substance gazeuse provoquant une turbulence, dirigée à partir du bas vers le haut dans la chambre de mesure (7). Les moyens de mesure (3) du dispositif sont divisés par une séparation (6) en deux parties, de telle sorte que l'impulsion de gaz est dirigée de façon à s'approcher du bas des moyens de mesure sur un côté (5) et du bas vers le haut sur l'autre côté (7) de la paroi (6).
