Abstract
PARA DETERMINAR LA CARGA DE UN FILTRO DE CARBON VEGETAL CON GASES Y VAPORES, SE MIDEN LA IMPEDANCIA ACUSTICA Y LA IMPENDANCIA ELECTRICA DE LA CAPA DE CARBON VEGETAL. CUANTO MAS CARGADO ESTE EL FILTRO, MAYOR SERA LA DENSIDAD DE LA CAPA DE CARBON VEGETAL Y, POR ELLO, SU CONDUCTIVIDAD ACUSTICA. LA CARGA DE UNA CAPA DE CARBON VEGETAL CON VAPOR DE AGUA PRODUCE UN INCREMENTO DE LA CONDUCTIVIDAD ACUSTICA ASI COMO DE LA CONDUCTIVIDAD ELECTRICA. SIN EMBARGO, UNA CARGA DE OTROS GASES O VAPORES NO INFLUYE SOBRE LA CONDUCTIVIDAD ELECTRICA. COMPARANDO LA IMPEDANCIA ACUSTICA Y LA IMPEDANCIA ELECTRICA, RESPECTIVAMENTE, DE UNA CAPA DE CARBON VEGETAL CARGADA PARCIALMENTE CON LA IMPEDANCIA DE UNA CAPA DE CARBON VEGETAL NO CARGADA Y MEDIANTE LA COMPARACION SUBSIGUIENTE DE LOS CAMBIOS DE IMPEDANCIA CAUSADOS POR DICHA CARGA, PUEDE ELIMINARSE LA INFLUENCIA DEL VAPOR DE AGUA. ES GENERADA UNA SEÑAL CORRESPONDIENTE A LA CARGA DEL FILTRO DE CARBON VEGETAL CON OTROS VAPORES Y GASES, CUYA SEÑAL PUEDE UTILIZARSE PARA INDICAR LA CONDICION DEL FILTRO Y PARA GENERAR UNA ALARMA SI EL FILTRO LLEGA A AGOTARSE
