A device for sensing a concentration of a combustible specie of interest (10, 20, 30, 50, 60) and a process analytic system (300) employing such sensors (10, 20, 30, 50, 60) are provided. The sensors (10, 20, 30, 50, 60) generally include a treatment or material that is adapted to increase the resistance of certain portions of the sensors (10, 20, 30, 50, 60) to exposure to sulfur. In one aspect, an improved sulfur-resistant process analytic system (300) includes a probe (302) with one or more sulfur-resistant sensors (10, 20, 30, 50, 60) therein coupled to a controller (308), a thermal control module (304), and a source of blowback gas (306).
L'invention a trait à des capteurs résistants au soufre (10, 20, 30, 50, 60), et à un système analytique de processus (300) faisant appel à de tels capteurs (10, 20, 30, 50, 60). Lesdits capteurs (10, 20, 30, 50, 60) comportent généralement un traitement ou un matériau permettant d'augmenter la résistance de certaines parties des capteurs (10, 20, 30, 50, 60) à l'exposition au soufre. Dans un mode de réalisation, un système analytique de processus résistant au soufre (300) comprend une sonde (302) contenant un ou plusieurs capteurs résistants au soufre (10, 20, 30, 50, 60) couplés à un contrôleur (308), un module de commande thermique (304), et une source de gaz de refoulement (306).
