Detection sensitivity is not determined by the machine alone. Actual results can change according to the product, packaging, contaminant, and production setup.
Key factors include:
• Contaminant size and density • Product density and thickness • Contaminant position inside the pack • Product orientation on the conveyor • Packaging material and number of layers • Conveyor speed • Product uniformity • Detector resolution, X-ray power, filters, thresholds, and software settings • Installation condition, cleaning, calibration, and maintenance
Higher-density materials such as metal, glass, ceramic, and stone are generally easier to identify than smaller or lower-density foreign objects. Dense, thick, or uneven products can reduce image contrast and make detection more difficult.
The most reliable way to confirm performance is through a validation trial using the actual product, packaging, line speed, and required contaminant samples.
