Metal detector

detector widely used in the food, beverage, and pharmaceutical industries to identify metallic contamination within packaged or loose products. Known for its durable stainless steel construction, this system uses a classic three-coil electromagnetic field system to detect ferrous, non-ferrous, and stainless steel particles.Because these units are built for specific manufacturing lines, they vary in conveyor length, belt type, and aperture size (the opening the product passes through).Core Technology & Operating ModesThe IQ2 processes products by tracking disruption in a radio-frequency magnetic field. To avoid "false triggers" from the inherent properties of certain goods, it calibrates itself across three distinct modes:Dry Mode: Used for dry products like coffee, tea, or deep-frozen foods. Since frozen water does not conduct electricity, this mode yields the machine's highest possible sensitivity.Resistive Mode: Configured for items with mild moisture content or those enriched with iron, such as baking flours, cocoa powder, or breakfast cereals.Reactive Mode: Optimized for items with heavy moisture or salt contents (e.g., fresh meats, pickles, cheese). The mode filters out the natural conductivity of the food so it doesn't trigger a false reject.Common Variations & Form FactorsDepending on the production environment, the IQ2 was manufactured in several configurations:Conveyorized Systems: The standard setup featuring an integrated food-grade rubber or modular Intralox belt. When metal is found, the system can either initiate a belt stop with an audible alarm or utilize an automatic air-blast/pneumatic pusher to eject the item.IQ2F (Ferrous-in-Foil): A specialized variant head tailored to scan products that are already packed in aluminum foil trays or wrappers, ignoring the packaging while hunting for hidden magnetic metal contamination.Pipeline & Gravity Systems: Non-conveyor variants built to scan liquids pumped through a tube or loose powders falling freely through a drop-thru funnel.Best Practices for OperationIf you are operating or maintaining a used Loma IQ2 unit, the official operational manual highlights several strict workflows:
