Abstract

Es wird eine Gassensoranordnung (40) mit einer Strahlungsvorrichtung (41-43),. einem Gasmessraum (49), einer Detektorvorrichtung (44-47) und einer Auswertevorrichtung (48) vorgeschlagen, wobei die Auswertevorrichtung die Strahlungsvorrichtung steuert, die Detektorsignale aufzeichnet und auswertet und die Messgaskonzentration abhängig vom Ausgangssignal der Detektorvorrichtung bestimmt. Die Strahlungsvorrichtung weist mindestens zwei Messstrahlungsquellen (41,42) und mindestens eine Referenz Strahlungsquelle (43) auf. Die Detektorvorrichtung ist so aufgebaut, dass sie die Strahlung nach deren Durchgang durch den Gasmessraum in einem Mess- bzw. in einem Referenzband jeweils räumlich und/oder zeitlich getrennt unabhängig empfangen kann, wobei die Auswertevorrichtung die Strahlungsquellen nach einem bestimmten Steuerungsalgorithmus betreibt und eine eventuelle Alterung der Gas sensoranordnung kompensiert und die Messgaskonzentration bestimmt.
