Abstract

LA AMBIGUEDAD EN LAS LECTURAS DE UN DETECTOR OPTICO DE BURBUJAS UTILIZADO EN UNA TUBERIA SE PUEDE REDUCIR DANDOLE A LA TUBERIA UNA FORMA DE PRISMA (10) DE MODO QUE CUANDO LOS DISTINTOS CONTENIDOS DE LA TUBERIA TIENE INDICES DE REFRACCION DIFERENTES, HAY UNA DIFERENCIA CLARA EN EL ANGULO DE SALIDA DEL HAZ LUMINOSO QUE SALE DE LA TUBERIA. LA FORMA PREFERENTE PARA LA TUBERIA COMPRIMIDA ES UN PRISMA TRIANGULAR. EL DETECTOR OPTICO DE BURBUJAS INCLUYE UN BLOQUE OPTICO CON UNA RANURA EN FORMA DE V Y UN BLOQUE DE SUJECION. EL BLOQUE OPTICO Y EL BLOQUE DE SUJECION PRESIONAN O "INTERCALAN" JUNTOS LA TUBERIA FLEXIBLE EN LA RANURA EN FORMA DE V Y LA DEFORMAN EN UNA SECCION TRANSVERSAL PRISMATICA TRIANGULAR. UN ELEMENTO DE INTERRUPTOR OPTICO CON FORMA GENERALMENTE DE U, QUE INCLUYE UN FOTOEMISOR (58) Y UN FOTODETECTOR (59), ENCAJA EN EL BLOQUE OPTICO DE TAL MODO QUE SE PUEDA DIRIGIR RADIALMENTE UN HAZ LUMINOSO DENTRO DE LA SECCION TRIANGULAR DE LA TUBERIA. EL BLOQUE DE SUJECION "REDUCE A UNA VENTANA" LALUZ TRASMITIDA Y RECIBIDA DEL INTERRUPTOR OPTICO PARA QUE SOLO PUEDA SER TRANSMITIDO UN CANAL DELGADO DE LUZ; ESTO MINIMIZA EL RUIDO OPTICO DURANTE EL PROCESO DE MEDICION. CUANDO HAY SUSTANCIAS SALINAS EN LA TUBERIA, LA LUZ SIGUE UNA TRAYECTORIA BASTANTE RECTA A TRAVES DEL BLOQUE OPTICO Y DE LA TUBERIA. NO ESTANTE, CUANDO HAY AIRE EN LA TUBERIA, LA LUZ SE REFRACTA ALEJANDOSE DEL FOTODETECTOR CON LO QUE LAS LECTURAS TIENEN UNA MENOR INTENSIDAD. SI SE MIDE LA CANTIDAD DE LUZ RECIBIDA EN EL FOTODETECTOR, SE PUEDE DETERMINAR SI HAY AIRE O SUSTANCIAS SALINAS EN EL TUBO.
