Abstract

Un sensor de gas para medir la concentración de un gas predeterminado comprende una fuente de luz (2) dispuesta para emitir pulsos de luz, un volumen de medición (10), un detector (4) dispuesto para recibir luz que ha pasado a través del volumen de medición (10), y un filtro adaptable (6) dispuesto entre la fuente de luz (2) y el detector (4) El sensor de gas tiene un estado de medición en el que pasa por lo menos una banda de longitud de onda que es absorbida por el gas y un estado de referencia en el que la banda de longitud de onda es atenuada en relación con el estado de medición. El filtro adaptable (6) está dispuesto para cambiar entre uno del estado de medición y el estado de referencia al otro por lo menos una vez durante cada pulso.
