Abstract

Die Erfindung betrifft einen Drucksensor (100) für ein Messsystem (10) zur Messung einer Konzentration von gas- und/oder aerosolförmigen Komponenten eines Gasgemisches mit einem Reaktionsträger (14), der zumindest einen Strömungskanal (42) aufweist, wobei der Strömungskanal (42) eine Reaktionskammer (46) mit einem Reaktionsstoff (48) bildet, welcher ausgebildet ist, um mit zumindest einer zu messenden Komponente des Gasgemisches oder einem Reaktionsprodukt der zu messenden Komponente eine optisch detektierbare Reaktion einzugehen, und einer Messvorrichtung (12), die eine Gasanschlussbaugruppe (5) zum Anschluss eines Gaszuflusskanals (16) und eines Gasabflusskanals (18) an den Strömungskanal (42) des Reaktionsträgers und eine Gasfördereinrichtung (28) zur Förderung des Gasgemisches durch den Strömungskanal (42) des Reaktionsträgers (14) umfasst. Der Drucksensor (100) ist ausgebildet, um eine Druckdifferenz eines durch die Gasförderbaugruppe (5) und/oder Strömungskanal (42) des Reaktionsträgers (14) strömenden Gasgemisches zu messen und ein elastisches Element (102) aufweist, welches ausgebildet ist, um sich in Abhängigkeit der Druckdifferenz zu verformen. Die Erfindung betrifft ferner ein Messverfahren, eine Messvorrichtung und einen Reaktionsträger für ein derartiges Messsystem.
