Abstract

Dispositivo captador electromagnético perfeccionado sensible a una modificación de un campo magnético que comprende al menos medios de emisión que crean alrededor de dicho captador un campo electromagnético, y medios de tratamiento de la señal entregada por los medios de recepción, cuando una mesa metálica se encuentra en el campo emitido, estando estos medios de emisión y estos medios de recepción generalmente regulados para un acoplamiento mínimo en ausencia de dicha masa metálica.
