Title
(DE) VERFAHREN ZUR BESTIMMUNG DES FÜLLUNGSGRADES EINER MISCHTROMMEL
(EN) METHOD FOR DETERMINING THE FILLING LEVEL OF A MIXING DRUM
(FR) PROCÉDÉ DE DÉTERMINATION DU NIVEAU DE REMPLISSAGE D’UN TAMBOUR MÉLANGEUR
Abstract
(DE)
Eine Mischtrommel wird von einem elektrischen Motor gedreht und dabei das Drehmoment des elektrischen Motors ermittelt. Anhand von gespeicherten Drehmomenten bei voller und leerer Mischtrommel wird beim Entleeren der Füllgrad der Mischtrommel bestimmt.
(EN)
The invention relates to a mixing drum which is rotated by an electric motor, wherein the torque of the electric motor is determined. The filling level of the mixing drum is determined during emptying on the basis of stored torque values for a full and for an empty mixing drum.
(FR)
Selon l'invention, un tambour mélangeur est entrainé en rotation par un moteur électrique et à cet effet, le couple du moteur électrique est déterminé. Sur la base des couples mémorisés lorsque le tambour mélangeur est plein et lorsqu’il est vide, le niveau de remplissage du tambour mélangeur est déterminé lors de son vidage.
