What type of metals can metal detectors detect in food industry

Metal detectors used in the food industry can detect a range of metal types, including ferrous, non-ferrous, and stainless steel metals. 

These include:

Ferrous metals: These are metals that contain iron, such as steel, and can be detected by metal detectors.

Non-ferrous metals: These are metals that do not contain iron, such as aluminum, copper, brass, and lead. Metal detectors can also detect these types of metals.

Stainless steel: Although stainless steel is not magnetic and cannot be detected by a metal detector, many metal detectors used in the food industry are designed to detect stainless steel contaminants using a variety of techniques, including magnetic, conductive, and magnetic field gradients.

It's important to note that the sensitivity of metal detectors can vary depending on the type and size of the metal contaminants, as well as the product being inspected. Regular testing and calibration of metal detectors is essential to ensure they are functioning properly and detecting all types of metal contaminants.
