Abstract

EL AVISADOR (SM) DISPONE DE UNA CAMARA (MK) DE MEDIDA, UN EMISOR (LS1) DE LUZ Y UN RECEPTOR (LE) DE LUZ CON LA CORRESPONDIENTE OPTICA, CUYA SEÑAL DE SALIDA REPRESENTA UN VALOR DE MEDIDA PARA LA DENSIDAD DEL HUMO. EN EL AVISADOR (SM) DE LUZ SE MIDE DE FORMA CONOCIDA LA HUMEDAD DEL AIRE EN LA CAMARA DE MEDIDA, SE AVERIGUA UN VALOR (MWF) DE HUMEDAD POR MEDIO DE UN EQUIPO DE LINEALIZACION-TAMAÑO DE MEDIDA Y, POR ENCIMA DE UN VALOR LIMITE DETERMINADO DEL VALOR (MWR) DE MEDIDA DE LA DENSIDAD DE HUMO, SE COMPENSA CON EL VALOR (MWF) DE MEDIDA DE HUMEDAD. EL VALOR (KMWR) DE MEDIDA DE DENSIDAD DE HUMO SE ELABORA POSTERIORMENTE PARA LA FORMACION DE CRITERIOS DE ALARMA. DE ACUERDO CON LA INVENCION SE DETECTA CON UN OTRO EMISOR (LS2) DE LUZ Y EL RECEPTOR (LE) DE LUZ YA EXISTENTE UNA CAPA (WT) DE HUMEDAD SOBRE LA OPTICA (EL) DE RECEPCION, EN DONDE SE MIDE PERIODICAMENTE LA DENSIDAD (MWR) DE HUMO CON EL PRIMER EMISOR (LS1) DE LUZ. SE ALTERNA CON ELLO DE FORMA TEMPORAL LA HUMEDAD (MWF) CON EL SEGUNDO EMISOR (LS2) DE LUZ, SIENDO MEDIDOS Y ELABORADOS POSTERIORMENTE AMBOS VALORES DE MEDIDA, CON LO CUAL LA CAPA (WT) DE HUMEDAD Y LA LUZ DEL SEGUNDO EMISOR (LS2) DE LUZ SE REFLEJAN Y CON ELLO LA SEÑAL DE SALIDA DEL RECEPTOR SE DEBILITA EN DEPENDENCIA DE LA INTENSIDAD DE LA CAPA DE HUMEDAD.
