A system for calculating and reporting slump in a delivery vehicle having a mixing drum (14) and hydraulic drive (16) for rotating the mixing drum, including a rotational sensor (20) configured to sense a rotational speed of the mixing drum, a hydraulic sensor (22) coupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, and a communications port (26) configured to communicate a slump calculation to a status system (28) commonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum.
L'invention porte sur un système de calcul et affichage de l'affaissement du béton dans un véhicule de fourniture de béton comportant un tambour mélangeur (14), un moteur hydraulique (16) entrainant le tambour, un détecteur (20) de la vitesse de rotation du tambour, un manomètre hydraulique (22) couplé au moteur hydraulique et mesurant la pression du fluide hydraulique requise pour entraîner le tambour, et un port de communication (26) communiquant le taux d'affaissement à un système d'affichage (28) usuel dans l'industrie du béton. C'est la vitesse de rotation du tambour qui permet le calcul de l'affaissement basé sur la mesure de la pression hydraulique nécessaire à l'entraînement du tambour.
