How does check weighing with X-Ray compare to conventional check weighing technology?
A conventional check-weigher cannot distinguish the weight of the product separate from the carton whereas the Smiths Eagle series can distinguish and separately weigh the product exclusive of the carton edges and ends. The carton weight and flap glue weights are not included in the product weight, thus eliminating a considerable source of variation. In addition, the X-ray can “see” inside the carton, and individually weigh several sub-components of the package. For example, there might be an underweight component and an overweight component which would average out correctly for a check-weigher (thus being missed). With x-ray inspection, however, the defects will both be detected as defects and the carton is rejected.
