Abstract
APARATO PARA MEDIR LA LUZ TRANSMITIDA A TRAVES DE UNA MUESTRA DE FLUIDO, PROPORCIONANDO UNA LECTURA DIRECTA DE LA MISMA. CONSTA DE UN FILTRO DE INTERFERENCIA DE COLOR (5) SITUADO ENTRE EL SOPORTE DE MUESTRA (3) Y EL FOTODETECTOR (4) DEL APARATO, QUE FILTRA TODOS LOS COLORES SALVO LA BANDA DE LUZ COLOREADA QUE HA DE MEDIRSE; DE UN CONVERTIDOR (6) QUE TRANSFORMA LA SEÑAL DE CORRIENTE PROCEDENTE DEL FOTODETECTOR EN UNA SEÑAL DE TENSION; DE UN CIRCUITO (8) DE RESPUESTA LOGARITMICA QUE TRANSFORMA LA SEÑAL DE TENSION EN UNA SEÑAL LOGARITMICA PROPORCIONAL AL LOGARITMO DE LA SEÑAL DE TENSION, Y DE UN VOLTIMETRO DIGITAL (1) QUE A PARTIR DE LA SEÑAL LOGARITMICA GENERA UNA SEÑAL LEGIBLE EN UN DISPOSITIVO DE VISUALIZACION DIGITAL (12).
