Abstract

Esta invencion se refiere a un sensor para medir las concentraciones de gas en una mezcla gaseosa, usando un tubo pequeño el cual está cerrado en un lado, y en cuyo exterior está dispuesto un sensor eléctrico a lo largo del tubo y cuyo extremo, opuesto al extremo cerrado está dispuesto en una cubierta, un entre espacio que rodea al tubo pequeño entre la cubierta y el tubo pequeño está sellado hermético al gas entre su cubierta y el tubo pequeño; para asegurar un sellado visible entre el gas que será medido y el gas de referencia incluso a altas temperaturas de operacion y al mismo tiempo para asegurar una pluralidad de funciones sensoras combinadas con una confiabilidad de alto contacto, se proveé un sellado al gas entre la cubierta y el tubo pequeño en el extremo opuesto al extremo cerrado, que es un extremo frío del tubo pequeño. por lo menos un contacto de sensor eléctrico que está eléctricamente aislado de la cubierta, está provisto en el exterior del tubo pequeño, y adicionalmente el por lo menos un contacto de sensor concluye en el extremo opuesto al extremo cerrado del tubo pequeño del tubo pequeño y está conectado a un alambre eléctrico.
