Abstract

Un sensor de microondas novedoso (10, 60, 70, 90, 200, 250, 280) proporciona medicion robusta, de bajo costo, de las propiedades eléctricas de sustancias fluidas. El sensor es adecuado para utilizacion en un recipiente o cano industrial y emplea trayectorias de transmision eléctrica paralela (12, 14) que difieren en longitud eléctrica o física. La longitud eléctrica de cada trayectoria de transmision, que puede ser una trayectoria bidireccional producida colocando un elemento reflectivo en cada trayectoria, está además determinada por las propiedades eléctricas del material bajo ensayo. La frecuencia (f) de senal que está siendo aplicada al sensor es variada de una manera conocida de modo que la diferencia de las longitudes eléctricas (Delta L) de las trayectorias de transmision (12, 14) se haga corresponder con un multiplo entero impar de una media longitud de onda. Cuando la frecuencia es así ajustada y se permite que las senales que han atravesado las trayectorias de transmision infieran coherentemente entre sí, entonces una senal resultante mínima o cero es obtenida. La frecuencia cero para la cual se obtiene una senal mínima es una medicion directa de la parte real de la permisividad eléctrica (er) del material bajo ensayo, y de este modo proporciona una medicion de la cual se puede deducir la composicion del material. El material bajo ensayo puede ser estacionario o puede fluir por el elemento de sonda sin afectar la característica de la medicion. Una importante aplicacion del método de medicion es la de determinar la calidad de vapor y una realizacion preferida de tal sensor es descripta. Otras sustancias fluidas pueden ser sensadas utilizando el sensor del presente invento.
