Abstract

UN DETECTOR DEL PASO DE GAS EN UN CIRCUITO CERRADO DE GAS (1) COMPRENDE DOS CELDAS DE DESVIACION (2, 5) CON UN FILTRO DE GAS EN MEDIO DEL PASO (4). CADA CELDA DE DESVIACION CONSISTE EN UNA FUENTE DE IONIZACION (21, 51), UNA ZONA DE RECOMBINACION TIPO LABERINTO Y UN ELECTRODO COLECTOR (22, 52). UN CIRCUITO DIFERENCIAL (7, 9) DERIVA UNA SEÑAL DIFERENCIAL DESDE LAS DOS SEÑALES DE SALIDA DE LAS DOS CELDAS DE DESVIACION. ESTA SEÑAL DIFERENCIAL DEPENDE SOLAMENTE DE LA CONCENTRACION DE GAS DEL CAMINO. LOS CAMBIOS DE TEMPERATURA Y CAMBIOS DE SUMINISTRO DE ENERGIA SON COMPENSADOS POR MEDIO DEL CIRCUITO DIFERENCIAL.
