Abstract

La invencion se relaciona con un dispositivo de medicion por microondas para detectar la carga de un flujo de dos fases con un medio portador gaseoso conteniendo particulas solidas y/o liquidas pequenas y diminutas, y para detectar gas contenido en un flujo fluido, preferentemente mediante ondas portadoras de guia de ondas. Una aplicacion preferida de la invencion es la deteccion de particulas solidas contenidas en el flujo de gas de sistemas de transporte neumaticos de material solido voluminosos empleados, por ejemplo, para hornos de carbon pulverizado de centrales termoelectricas de carbon. El dispositivo de medicion por microondas inventivo esta provisto de barras de campo que se extienden al interior del tubo de alimentacion estando dispuestas antes y despues de una seccion de medicion formada por una antenas de transmision y una antena de recepcion, siendo que las barras mencionadas interactuan con el tubo de alimentacion fabricado de un material conductivo como caja de resonancia para microondas emitidas al interior del tubo de alimentacion por medio de la antena de transmision, por lo que las microondas que se diferencian de las microondas emitidas respecto a su plano de polarizacion y/o fase como resultado de difraccion y/o reflexion en el exterior de la seccion de medicion son esencialmente eliminados mediante cortocircuito con el fin de evitar que los resultados de las mediciones sean distorsionados. El dispositivo inventivo tiene la ventaja particular de ser de construccion sencilla y facil instalacion aun en sistemas de tuberia de alimentacion voluminosa y ramificada.
