Abstract
DETECTOR DE HUMO DEL TIPO DE IONIZACION, DISEÑADO PARA EMITIR UNA SEÑAL DE SALIDA QUE ACCIONA UNA ALARMA CUANDO LA CONCENTRACION DE HUMO DE DICHO DETECTOR ALCANZA UN VALOR PREDETERMINADO. CONSTA DE UNA CAMARA (12) PROVISTA DE DOS ELECTRODOS, PRIMERO (16) Y SEGUNDO (14); DE MEDIOS PARA ESTABLECER UN FLUJO DE CORRIENTE IONICA ENTRE DICHOS ELECTRODOS, PRIMERO Y SEGUNDO; DE MEDIOS PARA LA APLICACION DE UNA TENSION ENTRE DICHOS ELECTRODOS; DE MEDIOS QUE RESPONDEN A UNA REDUCCION EN LA CORRIENTE IONICA HASTA UN VALOR PREDETERMINADO, PROPORCIONANDO UNA SEÑAL DE ALARMA; Y DE UN ELECTRODO DE COMPROBACION (18) DISPUESTO EN LA CAMARA, EL CUAL ESTA SOMETIDO A UNA TENSION QUE ES INFERIOR A LA TENSION DE UNO DE LOS ELECTRODOS (16, 14) Y SUPERIOR A LA TENSION DEL OTRO ELECTRODO.
