DEVICE FOR WEIGHING OF SUBSTANCES SUBJECT TO MIXING Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: invention is related to equipment for multicomponent weighing. In accordance with invention both components are fed into hopper out of master units. Device provides for possibility of periodic evaluation of actual values of rate of weighing of first component and factor of dependence of rate of weighing of second component on value of signal controlling weighing of second component with the aid of experimental actions on controlling input of drive of second feeder. For this unit controlling flow rate of second component is provided with capability to determine value and sign of experimental action and to realize it by addition of second feeder to working control over drive. Instruction for realization of experimental action goes from unit monitoring weighing process. EFFECT: increased precision of weighing thanks to monitoring of coming of each component in case of their simultaneous loading. 1 dwg
