Abstract
An apparatus and method used to detect metallized containers or other objects in closed packages traveling in a conveyor stream. The apparatus includes a pair of coil units mounted in association with a packaging conveyor such that the closed packages will pass therebetween. Appropriate field generation circuitry are connected to the coil units for producing a magnetic field. When the metallized containers pass through the magnetic field, the impedance across the coils will vary. The varying impedance is measured continuously, thus giving an indication as to whether the metallized object has been detected. If the package is nonconforming, steps can be taken to automatically remove it from the conveyor stream.
