Abstract

LA INVENCION SE REFIERE A UN MONITOR PORTATIL DE CONTAMINACION DE FLUIDOS ON-LINE. SE PROPORCIONAN RECURSOS (411, 411'') PARA CONECTAR EL MONITOR A UN CIRCUITO DE FLUIDOS, Y RECURSOS (2) PARA RETIRAR EL FLUIDO DEL CIRCUITO. SE UTILIZAN RECURSOS OPTICOS (4) PARA EXAMINAR EL FLUIDO RETIRADO DEL CIRCUITO Y DETERMINAR EL NIVEL DE CONTAMINACION MEDIANTE LA OBSERVACION DE LAS PARTICULAS EN EL MISMO, LOS RECURSOS OPTICOS QUE EXAMINAN EL FLUIDO A TRAVES DE UNA VENTANA (42) POR MEDIO DE UNA FUENTE LUMINOSA (45) DISPUESTA PARA PROYECTAR LA LUZ A TRAVES DE LA VENTANA Y EL FLUIDO. UN DETECTOR DE LUZ (47) DISPUESTO EN EL LADO OPUESTO DE LA VENTANA DE LA FUENTE LUMINOSA DISPUESTO PARA DETECTAR PARTICULAS EN EL FLUIDO QUE PASEN JUNTO A LA VENTANA MEDIANTE LA DETECCION DEL GRADO DE OSCURIDAD DE LA LUZ PRODUCIDA POR LAS PARTICULAS EN EL FLUIDO.
