The InspX X-Ray Checkweigh Solution Is an Accurate Alternative to High Speed Checkweigh Devices

InspX is pleased to announce the results of an extensive review of the accuracy of its X-Ray based checkweighing solution across multiple applications and package types. X-Ray based checkweighing works by calculating the weight of an object based on its density and the volume as determined from an X-Ray image. Unlike mechanical weighing, X-Ray based checkweighing is completely non-contact, which means there is absolutely no physical contact between the product and the X-Ray machine.

The advantage of X-Ray based checkweighing is that it is extremely accurate, even at very high line speeds – the fastest InspX X-Ray systems can operate at speeds in excess of 700 linear feet or 1000 containers per minute. Mechanical checkweighers capable of such speeds are often extremely expensive whereas X-Ray based checkweighing is an inexpensive software option on the existing ScanTrac system – and any ScanTrac can be field upgraded to include the software-based checkweigh option.

There are several key benefits to using an X-Ray based checkweigher versus a conventional gravimetric checkweigher. Since there is no physical contact between the product and the machine, product rotation doesn’t affect weight, “weigh-table bounce” from the inertial effect of packages doesn’t factor in, air currents in the tunnel have no effect, and any vibration won’t alter weight calculation. Additionally, unlike conventional checkweighers, product spacing, package length, or line speed won’t have any adverse effect on X-Ray checkweighing performance.

In addition, to avoiding some of the major pitfalls of conventional checkweighers, X-Ray based checkweighing offers the ability to selectively weigh areas of a product. For example, when checkweighing a packaged frozen dinner, each component in the package can be independently weighed and be measured against its own component weight standard rather than being a part of the overall package weight standard.

While electromechanical checkweighers often claim very high accuracies, those numbers rarely hold up in the tough production environments, with conditions like fast line speed, table bounce, product vibration, air currents, non-uniform product spacing, and rail drag. X-Ray checkweighing is not affected by any of these factors, making it ideal for performing in the unforgiving environment inside a food or beverage manufacturing facility.
