Abstract

DISPOSITIVO DETECTOR DE HUMOS, CON FUENTE DE IONIZACION DE BAJA INTENSIDAD. EL DISPOSITIVO ESTA CONSTITUIDO BASICAMENTE POR UN CONDENSADOR DE AIRE QUE TIENE DOS ARMADURAS (1,2). LA ARMADURA (1) CON FORMA DE CUBIERTA RETIENE GRAN VOLUMEN DE AIRE, Y LA ARMADURA (2) SOPORTA POR SOLSADURA UNA FUENTE RADIACTIVA EMISORA ALFA (3) DE MUY POCA INTENSIDAD UN ELECTRODO COLECTOR (4) DIVIDE EL ESPACIO DEL CODENSADOR EN DOS RECINTOS. EL PRIMERO DE ESTOS, COMPRENDIDO ENTRE EL ELECTRODO (4) Y A LA ARMADURA (1) , ES DE GRA VOLUMEN, ESTA SOMETIDO A UNA IONIZACION PARCIAL Y VE VARIAR SU CONSTANTE DIELECTRICA CON LA PRESENCIA DE HUMOS. EN EL OTRO RECITO, LA IONIZACION Y EL VALOR DE LA CONSTANTE DIELECTRICA SON CONSTANTES, TOMANDOSE ESTE ULTIMO COMO REFERENCIA.
