Abstract
The present invention pertains to a system for monitoring measured NOx values in an exhaust component, comprising a first NOx sensor having a first predetermined maintenance interval and a second NOx sensor having a second predetermined maintenance interval. The first and second NOx sensors are configured such that their first and second maintenance intervals are staggered. The present invention furthermore pertains to a method for monitoring measured NOx values in an exhaust component, comprising the steps of installing a first NOx sensor having a first predetermined maintenance interval in an exhaust component installing a second NOx sensor having a second predetermined maintenance interval after the first NOx sensor has been operating for a predetermined operation duration such that the first and second maintenance intervals are staggered by a maintenance timing offset.
