Modern Check Weighers for Precise Weight Measuring

July 2015 – Producers of finished food products are subject to restrictive regulations governing the product weight indicated on its packaging and the actual weight contained. By means of the highly accurate calculation methods applied by state-of-the-art control scales under and overweight content can already be detected during the manufacturing process and defective packs immediately be rejected.

A newcomer to this market is the C3000-System by Metler-Toledo Garvens, to name but one. Specialising in high-precision scales for major customers like packing plants, this Swiss company offers the possibility to link all used appliances with its innovation. The dynamic systems can check up to 600 products per minute thereby ensuring higher productivity. The industry benefits from automatically documented real-time data and quality parameters that can save and minimise wrong filling amounts by means of the link between the scales and other components such as the filling line. The weighing component of this modular system can be calibrated and weighs goods between three grams and ten kilograms. The scales can be configured for any given demand in terms of the type, size and packaging characteristics. Measuring the effectiveness of filling lines allows operators to optimise manufacturing processes and avoid costs. This means buyers and producers benefit to the same extent.

Check weighers with electro-dynamic force compensation combine two handy functions in one unit. Highly precise detectors in machines can sense even the smallest vibrations and guarantee and outcome of 100 percent homogeneous qualities. Special technologies such as Active Vibration Compensations and X-ray-functions with time dealy integration in OSC Checkweighers GmbH devices allow the identification of dirt particles as small as 500 µm.

Likewise, Bizerba check weighers make their marks with inspecting up to 160 packs per minute, removing them from the production flow if required. The machines obviate the need for manual random checks and calculate average values automatically for in-company statistics. Finally, Multivac's two-range scales for multi-track packaging lines allow operators to simultaneously establish weight on two tracks while optimising packaging processes with the downstream weighing module.
