摘要: Seeds falling down a chute pass between two spaced windows (38, 40) and mirrors (34, 36) facing each other across the width of chute. A linear array seven radiation emitters (CR1-CR7) direct beam seed path through slit aperture in window (38). The passes (40) to pair detectors (46, 48) connected parallel providing signal representing amount thereon. Because number (CR 1-CR7) array, is diffuse non-collimated so that no can be shadow another integrated reduction on accurately represents seeds passing through.
