Abstract

LA INVENCION SE REFIERE A UN APARATO QUE SE UTILIZA PARA MEDIR LA HUMEDAD DEL MATERIAL Y TRABAJA SEGUN UN METODO DIELECTRICO, DONDE RESALTA EL QUE , A TRAVES DE LA VARIACION DE LA HUMEDAD, SE MODIFICA LA CONSTANTE DIELECTRICA Y LA CAPACIDAD DEL MEDIO, EN DONDE SE SUMERGE UNA TUBERIA DE MEDICION. LOS DATOS GEOMETRICOS DE LA DISTRIBUCION SON CONSTANTES Y; SE EFECTUA UNA INTERRELACION ENTRE LA DURACION DE LOS ECOS QUE SUCEDEN A UNA SEÑAL DE ENTRADA, Y SE DETERMINA LA HUMEDAD DEL MATERIAL, CARACTERIZANDOSE PORQUE: EL DISPOSITIVO DE MEDICION, EMPLEA EN LA TUBERIA, SEÑALES DE ENTRADA EN FORMA DE IMPULSOS QUE PUEDEN SER TAN LARGOS COMO LA DURACION DEL ECO; EN LA ENTRADA DE DICHA TUBERIA, SE SUPERPONE LA EXCITACION Y EL ECO, EN EL DESARROLLO DE LA TENSION, Y SE DETERMINA LA DURACION DEL ECO. EL DISPOSITIVO SEGUN LA INVENCION TIENE ELEMENTOS MECANICOS Y ELECTRONICOS SENCILLOS CON GRAN PRECISION Y AMPLITUD.
