Hamer Brand Model 8800NWI – GV Net Weigh Bagging Scale

The Hamer Brand 8800NWi -GV (Gravity-Vibratory) 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 (load cells) mounted in a dust-tight, air purged compartment. The FASTRAC VI™ control platform features an Allen Bradley CompactLogix PLC and an interactive, 7” Red Lion Color HMI.  Highlights of the program include: Intuitive screen layout, 60 customizable (alpha-numeric) program storage capacity, auto-calibrate with user selectable frequency, auto-tare for compensation of product buildup, on-board diagnostics, real-time data acquisition (last 1000 weighments) along with optional data collection, reporting and remote monitoring/troubleshooting capabilities via Ethernet communications. Fills flat and gusseted multi-wall paper, polyethylene, and woven polypropylene bags ranging from 10 to 24 inches in width.  The Model 8800NWi -GV scale can be used in conjunction with our bag hangers or integrated with our fully automated handling systems.  Hamer-Fischbein may require product samples and bags for testing purposes.
