Advanced metal detection equipment using fluxgate magnetometers

摘要

Advanced metal detection apparatus according to the present invention may comprise a plurality of magnetometers for sensing a magnetic field and for producing output data signals relating to the detected magnetic field. The magnetometers may be arranged along a first row and define a sensing area. A signal processing apparatus connected to each of said plurality of magnetometers is responsive to the output signals produced thereby and generates a human-readable display indicative of the presence of the ferromagnetic object within the sensing area.
