4.9.1.2 – Photo/Graphic TBDAs a major contributor to formulation quality and consistency, feeder performance rightly deserves close attention and concern. ArticlePublished: 6/16/2011
4.9.2.2 – RepeatabilityRepeatabilityThe performance statistic most familiar to feeder users, repeatability quantifies the degree to which a feeder’s discharge stream varies over brief time intervals, producing a snapshot of one dimension... ArticlePublished: 6/12/2011
4.9.3.2 – Timescale GraphicAn issue of growing importance in the specification and measurement of feeder repeatability relates to catch sample duration. ArticlePublished: 6/12/2011
4.9.4.2 – Linearity GraphicAssuming a properly spanned feeder (a calibration scaling process resulting in measured and requested feed rate being equal at a specified operating rate), a feeder’s linearity measurement quantifies how well i... ArticlePublished: 6/11/2011
4.9.5.2 – Stability GraphicA perfectly performing feeder is worth little if it can’t maintain its performance over the long haul.Historically, many factors contributed to performance drift such as feeder type, analog control and weigh sy... ArticlePublished: 6/10/2011
