Abstract

PARA LA MEDICION DEL LLENADO DE RECIPIENTS METALICOS POR MEDIO DE ONDAS ELECTROMAGNETICAS CORTAS SE PROPONE UN DISPOSITIVO DE MEDICION COMPLETO, INCLUYENDO LA ANTENA DE BOCINA FUERA DEL RECIPIENTE. LAS ONDAS TRANSMITIDAS SON DIRIGIDAS SOBRE EL MEDIO A SER MEDIDO A TRAVES DE UNA ABERTURA PERFORADA EN LA PARED DEL RECIPIENTE. LA ABERTURA SE CIERRA POR MEDIO DE UNA PLACA DE VIDRIO O CERAMICA. PARA HACER POSIBLE LA UTILIZACION RECONOCIBLE DE SEÑAL DENTRO DEL ECO DE INTERFERENCIA QUE APARECE A PARTIR DE LA REFLEXION MULTIPLE DE LAS ONDAS ELECTROMAGNETICAS A PARTIR DE LA PLACA CERAMICA O DE VIDRIO, UNA CAPA DE AMORTIGUACION DE UN MATERIAL AMORTIGUADOR DE TIPO CONOCIDO SE INSERTA ENTRE EL COMPONENTE DE ACOPLAMIENTO DE MICROONDA Y LA SUPERFICIE DE LA PLACA CERAMICA O DE VIDRIO. PARA OBTENER UNA RELACION OPTIMA SEÑAL-RUIDO, EL FACTOR DE AMORTIGUACION Y LA DISTANCIA ENTRE EL DISPOSITIVO DE MEDICION DE NIVEL EN LA DIRECCION AXIAL DE LA ABERTURA DEL RECIPIENTE Y LA SUPERFICIE DE LA PLACA CERAMICA O DEVIDRIO PUEDE SER AJUSTADA.
