Inline Metal Detectors

Accuracy depends on sensitivity settings and product characteristics. Busch Machinery's inline units detect ferrous (Fe) contaminants as small as 0.8mm and stainless steel (SUS) as small as 1.5mm. Models combining check weighing with metal detection, like the BM-GC series, provide the most comprehensive accuracy by verifying both weight compliance and contamination in a single pass.

Detection sensitivity varies by model and package size. Busch Machinery's inline detectors identify ferrous metal fragments as small as 0.8mm and stainless steel contaminants as small as 1.5mm to 2.5mm, depending on the checking diameter and belt speed configuration selected for the application.

Yes. Busch Machinery offers combined systems, such as the BM-GC212 through BM-GC320 series, that integrate check weighing and metal detection into a single stainless steel unit. This allows simultaneous weight verification and contamination screening, automatically rejecting underweight, overweight, or metal-contaminated products without slowing production.

Inline metal detectors are widely used in food processing, pharmaceutical manufacturing, chemical processing, and seafood packaging. They inspect packaged goods like snacks, dried meats, coffee, and frozen foods, as well as loose powders and granules, to prevent metal contamination before products reach store shelves or downstream processing.

Look for CE certification confirming compliance with European safety and performance standards, food safety compliance for hygienic construction, and IP65 waterproof ratings for washdown environments. These certifications ensure the equipment meets contamination detection reliability and durability requirements expected in food, pharmaceutical, and chemical manufacturing settings.

Once metal detection sensors identify a contaminant, the system activates a rejection mechanism suited to the product type. Common methods include air blowing for lightweight items, arm-reject or pneumatic pushers for packaged goods, and slide-type diverters for bulk materials, ensuring contaminated products are removed without disrupting line flow.
