Abstract

Un convertidor foto eléctrico de tamaños de partículas contenidas en un flujo de gas en impulsos eléctricos, que comprende una cámara con unos medios para dirigir un flujo de aerosol a y desde la cámara que está ópticamente conectada a unos medios de iluminación que forman un flujo luminoso convergente para iluminar el flujo de aerosol, y a un foto receptor dispuesto de manera que su eje óptico, así como el eje óptico de los medios de iluminación y el eje del flujo de aerosol se intersecan todos en ángulo recto dentro de la cámara, un canal para transmitir parte del flujo luminoso de los medios de iluminación al foto receptor, un formador de impulsos luminosos de calibración acomodado en el canal para transmitir parte del flujo luminoso de los medios de iluminación al foto receptor y que comprende un diafragma y un obturador mecánico, caracterizado porque el canal para transmitir parte del flujo luminoso de los medios de iluminación al foto receptor contiene dos espejos dispuestos en la cámara a través de los ejes ópticos de los medios de iluminación y del foto receptor, respectivamente más alla del punto de intersección de estos ejes ópticos, mientras que el diafragma y el obturador mecánico están interpuestos entre los espejos, comprendiendo el obturador mecánico un vástago con un accionamiento de vaivén.
