Abstract

SE PROPONE UN DISPOSITIVO PARA LA DETERMINACION DE LA DENSIDAD Y CONCENTRACION DE COMPONENTES VISIBLES EN FLUIDOS, EN PARTICULAR PARA MEDICION DE TURBIDEZ DE HUMOS DE EXHAUSTACION DE UN VEHICULO A MOTOR. UNA CAMARA (10) DE MEDICION QUE PUEDE RECIBIR EL FLUIDO A SER MEDIDO DISPONE DE UN PRIMER RECEPTOR (16) DE LUZ OPUESTO A UNA FUENTE (15) DE LUZ QUE EMITE UN RAYO DE LUZ HACIA EL RECEPTOR (16) DE LUZ. ESTA DISPOSICION PERMITE LA IMPLANTACION DE UN METODO OPACIMETRICO QUE EVALUA LA ATENUACION DE LUZ COMO UNA FUNCION DE LA TURBIDEZ. ADICIONALMENTE, UN SEGUNDO RECEPTOR (19) DE LUZ CAPTA LA LUZ ESPARCIDA A PARTIR DE LA VIA DEL RAYO DE LUZ A TRAVES DE LA CAMARA (10) DE MEDICION. DE ESTA FORMA PUEDE SER IMPLANTADO UN METODO DE LUZ DISPERSA, EN DONDE LA PORCION DE LUZ DISPERSA SE DETECTA COMO UNA MEDIDA PARA LA CONCENTRACION DE PARTICULAS CORRESPONDIENTES AL ESPARCIMIENTO DE LUZ EN EL MEDIO EXAMINADO. UN DISPOSITIVO DE EVALUACION PUEDE EVALUAR LAS SEÑALES DE MEDICION (TURBIDEZ Y LUZ ESPACIADA) AL MISMO TIEMPO O DE FORMA ALTERNATIVA.
