© Siemens AG 2015 SITRANS Weighfeeders SITRANS WW100 Introduction ■ Overview SITRANS WW100 is a high-accuracy, low-capacity weighfeeder used for minor ingredient additives. ■ Benefits • • • • • • High accuracy High turn down ratio 100 … 10 % of capacity Corrosion resistant components Fast and easy belt removal for replacement or cleaning Simple installation, easy to clean and maintain Pre-programmed drive for servo motor control 5 ■ Application SITRANS WW100 is one of the most accurate in-motion weighing systems on the market. It is specially designed for high accuracy on light loading processes. The design eliminates material buildup to ensure accurate, reliable measurement. The unique long length platform weigh bridge mounts directly to a corrosion-resistant platform load cell. An adjustable mechanical shear gate profiles the material and fixes the correct material bed depth for a given material particle size. The belt speed can be automatically adjusted to attain the correct feed rate. Standard components include an anti-static food grade belt, gravity tensioned roller, tail pulley driven belt for maximum weighing accuracy, belt tracking rollers, belt scraper and plow for self-cleaning.
