Metal detection and X-ray inspection are both used to identify foreign objects, but they solve different problems. Metal detectors are highly effective for detecting ferrous, non-ferrous and stainless-steel contamination in many production environments.
X-ray inspection can detect a wider range of foreign materials depending on product density and application. In addition to metals, X-ray systems may detect materials such as glass, stones or other dense contaminants.
When metal detection is often suitable
- The main risk is metallic contamination.
- The product or material flow is consistent.
- The line needs robust and cost-effective detection.
- The system is used for machine protection or product quality control.
When X-ray inspection may be considered
- The risk includes non-metallic foreign objects.
- The product is already packaged.
- Additional inspection functions may be valuable.
- The application requires a broader detection method.
The right choice depends on risk profile, product characteristics and production requirements. A technical review of the application is usually the best starting point.
