Abstract

PROCEDIMIENTO PARA DETECTAR EL ESTADO (ABIERTO, CERRADO, INTERMEDIO) DE UNA VALVULA QUE INCORPORA UNA BOBINA ELECTRICA (6) DE NUCLEO MOVIL (8) DESPLAZABLE LINEALMENTE EN CORRESPONDENCIA CON EL DESPLAZAMIENTO DEL ORGANO OBTURADOR DE LA VALVULA, SEGUN EL CUAL: SE ASOCIA CON DEMORA A LA VALVULA UN CIRCUITO ELECTRICO OSCILANTE QUE INCLUYE LA SUSODICHA BOBINA (6) Y CUYA FRECUENCIA DE OSCILACION DEPENDE DE LA POSICION DEL NUCLEO (8) EN LA BOBINA; EN EL MOMENTO DE LA DETECCION, SE ACERCA LA BOBINA (6), COAXIALMENTE A LA MISMA, UNA SEGUNDA BOBINA (12); SE PROVOCA UNA VARIACION DEL FLUJO MAGNETICO EN EL ENTORNO DE LA PRIMERA BOBINA (6) EN LA QUE HAY UNA CORRIENTE ALTERNA AMORTIGUADA; SE DETECTA LA FRECUENCIA DE LA TENSION ALTERNA INDUCIDA EN RETORNO EN LA SEGUNDA BOBINA (12); SE DEDUCE LA POSICION DEL NUCLEO (8) EN LA PRIMERA BOBINA (6) Y SE DEDUCE FINALMENTE EL ESTADO (ABIERTO, CERRADO, INTERMEDIO) DE LA VALVULA (1).
