Abstract

UN SENSOR OPTICO PERCIBE UNA ANALITA EN UN FLUIDO.EL SENSOR TIENE UN DISPOSITIVO SENSIBLE A RESONANCIAS EN LA SUPERFICIE (17) QUE REFLEJA LA LUZ DESDE UNA FUENTE DE LUZ (11) A UN DETECTOR DE LUZ(34).UNA APERTURA DE CLAVIJA HUECA (33) DETERMINA QUE PARTE DE LA LUZ PERMITE ALCANZAR EL DETECTOR.CUANDO LA ANALITA SE EXPONE AL DISPOSITIVO ESTE RESPONDE ALTERANDO LA INTENSIDAD DE LUZ REFLEJADA EN EL DETECTOR. PRODUCIENDO UNA SEÑAL DE SALIDA REPRESENTATIVA POR EJEMPLO DE LA CONCENTRACION DE ANALITA QUE SE INDICA EN UNOS MEDIOS INDICADORES.
