Abstract

DETECTOR DE PROXIMIDAD INDUCTIVO QUE COMPRENDE UNA FUENTE DE ALIMENTACION Y UNA BOBINA. LA FUENTE DE ALIMENTACION ESTA DISPUESTA PARA PROPORCIONAR A LA BOBINA UNA CORRIENTE PERIODICA CUYA DURACION DE CONDUCCION ES INFERIOR AL PERIODO DE ALIMENTACION. LA RESPUESTA DE LA PIEZA A DETECTAR SE MIDE DURANTE LA DURACION EN LA QUE LA CORRIENTE EN LA BOBINA ES PRACTICAMENTE NULA.
