Abstract

LA INVENCION SE REFIERE A UN SENSOR PARA LA MEDICION DE LA VELOCIDAD RELATIVA ENTRE UN CILINDRO AMORTIGUADOR (1) Y UN PISTON DE AMORTIGUACION (8) QUE SE MUEVE EN EL CILINDRO DEL AMORTIGUADOR (1) UNIDO CON EL VASTAGO DEL PISTON (3). EL SENSOR SE COMPONE DE UN IMAN PERMANENTE (5) Y DE UN DEVANADO DEL SENSOR (7) FORMADO COMO BOBINA CILINDRICA, QUE ACTUA CONJUNTAMENTE CON EL IMAN PERMANENTE (5), PARA LO CUAL EL IMAN PERMANENTE (5) ESTA EN UNION DIRECTA O INDIRECTA CON UNA DE LAS PIEZAS QUE SE MUEVEN RELATIVAMENTE ENTRE SI Y EL DEVANADO DEL SENSOR (7) ESTA DISPUESTO DIRECTO O INDIRECTAMENTE SOBRE LA OTRA DE LAS PIEZAS QUE SE MUEVEN RELATIVAMENTE ENTRE SI, Y LAS PIEZAS QUE SOPORTAN EL IMAN PERMANENTE (5) Y EL DEVANADO DEL SENSOR (7) PARA EL CAMPO MAGNETICO DEL IMAN PERMANENTE (5), FORMAN UN CIRCUITO MAGNETICO CERRADO.
