When you pick the right metal detectors, you make your products safer and follow the rules. High-sensitivity systems can lower metal problems by up to 80%. You keep your customers safe and protect your business name.

How Industrial Metal Detectors Work

Detection Principles

Industrial metal detectors find metal by using coils. There is one transmitter coil and two receiver coils. The transmitter coil sends out an electromagnetic field. If metal goes through, the field changes. The receiver coils notice these changes. They can tell what kind of metal it is. It could be ferrous, non-ferrous, or stainless steel.

  • The transmitter coil makes a field to spot metal.

  • The receiver coils sense changes from metal.

  • The size of the opening affects how well it works.

  • The middle of the opening is not very sensitive.

COSO Electronic uses smart detection algorithms. These help you find tiny metal pieces. You get fewer false alarms. Your products stay safer.
