TOTALIZER FOR WEIGHING SYSTEMS

摘要

A weighing system totalizer wherein a pulse generator produces pulses at a constant repetition frequency to be counted in by a counting device, wherein a digital-to-analog converter cumulatively converts the generator-produced pulses into a feedback d.c. signal, and wherein a signal comparing circuit is responsive to the feedback d.c. signal and to a weight-representing d.c. signal to start and stop operation of the pulse generator for providing a generator-produced pulse train in which the number of pulses is representive of the magnitude of the weight-representing d.c. signal.
