Abstract

LA PRESENTE INVENCION SE REFIERE A UN DETECTOR INCREMENTAL DE POSICION Y/O DE VELOCIDAD, DEL TIPO QUE COMPRENDE UN ELEMENTO MOVIL (1) EN MATERIAL SUAVE QUE PRESENTA AL MENOS UN DIENTE MOVIL EN UNA DIRECCION OY ENFRENTE DE UN IMAN PERMANENTE (9) IMANTADO SEGUN UNA DIRECCION OZ SENSIBLEMENTE PERPENDICULAR AL EJE OY Y UNA SONDA (10) SENSIBLE AL SENTIDO Y A LA INTENSIDAD DE UN CAMPO MAGNETICO, TAL COMO UNA SONDA DE HALL, DISPUESTA EN EL ENTREHIERRO COMPRENDIDO ENTRE EL IMAN (9) Y EL DIENTE DEL ELEMENTO MOVIL DE TAL MANERA QUE SU EJE DE MAYOR SENSIBILIDAD ESTE SENSIBLEMENTE ORIENTADO SEGUN EL EJE OZ. LA SONDA DE HALL (10) ESTA SITUADA CERCA DE UN PUNTO SINGULAR DEL EJE OZ DONDE EL VALOR MEDIO DEL CAMPO MAGNETICO ES PEQUEÑO Y PREFERENTEMENTE INFERIOR A +/- 20MT Y ES SENSIBLEMENTE IGUAL AL VALOR MEDIO DEL CAMPO DE BASCULAMIENTO DEL CIRCUITO INTEGRADO ASOCIADO A LA SONDA DE HALL.
