Beschreibung
Zusammenfassung:	The invention relates to a system (10) for monitoring a measured NOx value in an exhaust gas component (20), the system (10) comprising a first NOx sensor (1) having a first predetermined maintenance interval (M1) and a second NOx sensor (2) having a second predetermined maintenance interval (M2). The first NOx sensor (1) and the second NOx sensor (2) are configured such that their first maintenance interval (M1) and second maintenance interval (M2) are offset. The invention also relates to a method for monitoring NOx values measured in an exhaust gas component (20), comprising the steps of installing (S10) a first NOx sensor (1) having a first predetermined maintenance interval (M1) in the exhaust gas component (20), installing (S20) a second NOx sensor (2) having a second predetermined maintenance interval (M2) after the first NOx sensor (1) has been operated for a predetermined operation duration, the first maintenance interval (M1) and the second maintenance interval (M2) are offset by the maintenance tim
