Abstract

EL DISPOSITIVO COMPRENDE, POR UNA PARTE, UNA ESCALA ALARGADA (7), FORMADA POR UNA SUCESION DE POLOS NORTE Y POLOS SUR MAGNETICOS, Y, POR OTRA PARTE, UNA CABEZA (9) DE MEDICION, CON, AL MENOS, UN PRIMER Y UN SEGUNDO DETECTORES (21, 23) DE CAMPO MAGNETICO, QUE ESTAN SOMETIDOS AL EFECTO DE UN CAMPO MAGNETICO, COMO UNA FUNCION DEL TIEMPO, DEBIDO AL PASO ALTERNATIVO DE LOS POLOS NORTE Y SUR DURANTE UN DESPLAZAMIENTO (15) DE LA ESCALA EN SU DIRECION LONGITUDINAL CON RESPECTO A LA CABEZA DE MEDICION. LOS DOS DETECTORES (21, 23) DE CAMPO MAGNETICO ESTAN COLOCADOS DE FORMA QUE SIEMPRE ESTEN EL UNO FRENTE AL OTRO, UNO EN EL MISMO PUNTO SOBRE LA ESCALA (7), SIENDO EL PRIMER DETECTOR (21) SENSIBLE A LAS VARIACIONES EN EL COMPONENTE DEL CAMPO MAGNETICO QUE SE EXTIENDE PARALELO A LA DIRECCION LONGITUDINAL DE LA ESCALA (7), Y EL SEGUNDO DETECTOR (23) SIENDO SENSIBLE A LAS VARIACIONES EN EL COMPONENTE QUE SE EXTIENDE PARALELO A LA LINEA (19) DE CONEXION ENTRE LA ESCALA (7) Y LA CABEZA (9) DE MEDICION. DEBIDO A QUE LOS PUNTOS DONDE SE INVIERTE LA DIRECCION DE ESTOS COMPONENTES DE CAMPO MAGNETICO SE CORRESPONDEN CON PUNTOS DIFERENTES SOBRE LA ESCALA (7), LAS SEÑALES DE SALIDA DE LOS DOS DETECTORES (21, 23) ESTAN DESFASADAS LA UNA RESPECTO A LA OTRA, CON LO QUE LA DIRECCION DEL DESPLAZAMIENTO PUEDE DETERMINARSE CON FACILIDAD.
