Abstract

EL INVENTO ES UN CAPTADOR DE POSICION. TIENE POR OBJETO UN CAPTADOR DE POSICIOON DESTINADO A MEDRI LA SEPARACION DE POSICION, SEGUN UNA DIRECCION DADA, DE UNA PRIMERA PIEZA TAL QUE UN ELEMENTNO DADO DE UN EJE DE VEHICULO FERROVIARIO CON RELACION A UNA SEGUNDA PIEZA FIJA TAL QUE UN RAIL SOBRE EL CUAL CIRCULA DICHO EJE. SE CARACTERIZA PORQUE COMPRENDE UNOS MEDIOS (11,12) PARA ELABORAR ENCIMA DE LA SEGUNDA PIEZA (10) UN CAMPO MAGNETICO Y UNOS MEDIOS (15) PARA MEDIR EL VALOR DE SU COMPONENTE SEGUN DICHA DIRECCION (OY), LA VARIACION DE ESTE VALOR ES PROPORCIONAL A DICHA SEPARACION DE POSICION. APLICACION EN LA MEDIDA DE LOS EJES DE UN VEHICULO SOBRE RAIL.
