Hamer Brand Model 8800NW Blending Scale

Our Hamer Model 8800NW Integrated Net Weigh Bagging Scale is designed for optimum bagging speed and consistency in weight accuracy for packaging free and semi-free flowing products. The unit comes with an air operated, double-door weigh hopper suspended from dual strain gauge weigh sensor modules mounted in a dust-tight, air purged compartment. The FASTRAC VI™ control platform features an Allen Bradley CompactLogix PLC and an interactive 7” color HMI. Highlights of the program include: intuitive screen layout, 60 customizable  program storage capacity, auto-calibrate with user selectable frequency, auto-tare for compensation of product buildup, on-board diagnostics, real-time data acquisition along with optional data collection, reporting and remote monitoring/troubleshooting capabilities via Ethernet communications. The 8800NWi fills flat and gusseted multi-wall paper, polyethylene and woven polypropylene bags ranging from 10 to 24 inches in width and can be used in conjunction with our bag hangers or integrated with our automated handling systems. It is available in gravity, vibratory gravity, or belt feed configurations in simplex or duplex with a variety of options to specifically fit your application.
