Abstract

APARATO PARA DETECTAR EL EMPLAZAMIENTO DE LA EXTREMIDAD DE UN ELEMENTO DE FORMA ALARGADA. COMPRENDE BOBINAS ELECTRICAS POR LAS QUE PASA SUCESIVAMENTE EL ELEMENTO, VARIANDO LA INDUCTANCIA DE CADA BOBINA AL PASAR POR ELLA; UN CONECTOR DE LAS BOBINAS EN CONJUNTOS, CADA UNO CON DOS GRUPOS DE BOBINAS CONECTADAS EN PARALELO Y CON LOS DOS GRUPOS EN SERIE EN UN NODO COMUN; UNA FUENTE DE CORRIENTE ALTERNA CONECTADA A LOS CONJUNTOS DE BOBINAS Y A UN PAR DE IMPEDANCIAS EN SERIE; Y UN GENERADOR DE SEÑAL DE SALIDA QUE RESPONDE AL CAMBIO SUCESIVO DE IMPEDANCIA DE CADA BOBINA AL PASO DEL ELEMENTO, QUE GENERA SEÑALES REPRESENTATIVAS DE POSICION DE LA EXTREMIDAD DE DICHO ELEMENTO DE FORMA ALARGADA RESPECTO A DICHAS BOBINAS.
