摘要： A device (1) for detecting metallic contaminants (M) in a product (P) using a signal (S) received from a coil-based metal detector (2) comprises a calibration module (11) configured to determine a product-specific, bowtie-shaped detection envelope by receiving from the metal detector (2) during a calibration phase signals (S) with a resistive component (R) and a reactive component (X) for one or more specimens of the product (P). The device (1) further comprises a detection module (12) configured to compare, in a coordinate system for the resistive and reactive components, a vector representation of the signal (S) to the product-specific, bowtie-shaped detection envelope, and to indicate a presence of a metallic contaminant (M) in the product (P) when the vector representation of the signal (S) extends to an area outside the bowtie-shaped detection envelope.
