Weigh feeder system

摘要: Disclosed herein is an automatically controlled weigh feeding apparatus including a container prefilled with substance, device for discharging the substance from at controllable weight, weighing and its contents producing electrical signal proportional to that first amplifier amplifying signal, analog-digital converter coupled said digital computer computing weight of remaining in container. A second ramp off-set circuit which by inputs means having stepping output applied as input maintain within given selected range amplitude during one time cycle operation. interposed between computer. The adapted compute corrective based on received controlling discharge
