Abstract

La presente invencion se refiere a un dispositivo de seguridad para cerrar el flujo de gas de un artefacto quemador de gas en presencia de vapores inflamables. La resistencia de un sensor de vapores inflamables de resistencia variable es monitoreada por un microprocesador que controla la operacion de una valvula de flujo de gas. Cuando la medida de la resistencia indica la presencia de una concentracion preseleccionada de vapores inflamables, la valvula de flujo de gas es cerrada y el sistema de ignicion es desactivado.
