The Metal Detector
The metal detector is constructed as a multiple-segment sensor with the width of each segment or detection zone dictated by the customer’s individual needs. This makes it possible to assign detected metal to a definite area or ‘zone’ across the product width. Due to extremely high sensitivities of the individual segments, metal will be detected across the entire width of the segment. Typically, a 0.012 – 0.024 in. (0.3 – 0.6 mm) metal ball can be detected depending on distance from the sensing face.
