How to Choose the Right Metal Detector for Your Operation?

DougMcMillon

A metal detector is an electronic device designed to identify the presence of metal nearby. It operates by transmitting an electromagnetic field and analyzing the signal that returns from any conductive material. Beyond security screenings, metal detectors are particularly vital in food and pharmaceutical production, as they ensure product safety. Selecting the appropriate metal detector machine involves understanding your product, the type of packaging, and the operational environment.

Key Factors to Consider
Product Properties: Moist or conductive foods can sometimes mimic metal, leading to false positives. Select a food metal detector specifically designed to overcome these challenges.

Packaging Materials: Foil or metallized film packaging may interfere with detection. In such cases, consider X-ray inspection as an alternative.

Throughput Speed: Ensure that the metal detection system can inspect products at the speed of your production line.

Reject System Compatibility: Your detector should seamlessly integrate with pushers, air blasts, or diverters for the automatic removal of contaminants.

Environmental Conditions: Is your facility suitable for washdown? Opt for waterproof, stainless-steel detectors for wet environments.​​
