Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA REDUCCION DE FALSAS ALARMAS, PRODUCIDAS POR GASES PERTURBADORES, EN INSTALACIONES DETECTORAS-AVISADORAS DE GASES, EN LAS QUE COMO ELEMENTO SENSIBLE A LOS GASES SE EMPLEA UN SEMICONDUCTOR DE OXIDO METALICO QUE FUNCIONA A TEMPERATURA CONSTANTE. EL PROCEDIMIENTO SE CARACTERIZA PORQUE AL APARECER UNA SEÑAL DE SALIDA ORIGINADA POR UNA COMPOSICION DESCONOCIDA DE GASES O VAPORES Y DEBIDA A LA VARIACION DE LA CONDUCTIBIDAD DEL ELEMENTO SENSIBLE A LOS GASES, SE VARIA RAPIDAMENTE LA TEMPERATURA DE DICHO ELEMENTO Y SE ENVIAN TANTO EL SIGNO COMO LA MAGNITUD DE LA VARIACION ADICIONAL, ASI RESULTANTE, DE LA SEÑAL DE SALIDA A UN CIRCUITO ELECTRONICO PARA LA DISCRIMINACION DEL GAS PERTURBADOR.
