Technology Explained: Weight Inspection with X-Ray Systems
When people think of X-ray inspection systems, foreign object detection is usually the first application that comes to mind. However, modern systems offer many additional quality assurance capabilities. One particularly valuable feature is integrated weight inspection.
Weight Control Using Existing X-Ray Data
Unlike a conventional checkweigher, product weight is not determined mechanically. Instead, the X-ray system uses the information already generated during the inspection process. After several reference products have been weighed and taught into the system, the software calculates the relationship between the measured X-ray values and the actual product weight. The system can then automatically determine the weight of all subsequent products of the same type.
Ideal for Multi-Pack Products
This function is especially useful for multipacks. Yogurt trays, for example, can be inspected for underfilled or missing cups. Any deviation from the defined tolerance limits is detected immediately and reported as a quality defect.
More Quality Assurance in a Single System
Another advantage is the combination with segmentation functions. This allows individual product areas or components to be evaluated separately. As a result, inspection tasks can be performed that would be difficult or even impossible with a conventional mechanical scale.
This makes an X-ray inspection system much more than a tool for foreign object detection. It helps manufacturers monitor product quality, completeness, and fill levels during the production process while reducing the need for additional inspection equipment.
