From a human safety standpoint, metallic contaminant detection systems are necessary in the food and pharmaceutical industries. If products are packaged in metal wrappings, the standard eddy current method should not be used after packaging. Several groups have developed a SQUID based detection system which measures the remanent magnetism of contaminants. Although that system can satisfy requirements, liquid nitrogen maintenance or a cryocooler is needed. Here we present a novel detection system based on an induction gradiometer. This system is free from heavy cooling system, and the magnetic sensor consists of air-cored coils and simple electronics only.
