Nernex NOx Sensor Technology
Nernex develops emissions-sensing products around the precise measurement and control required by modern diesel exhaust aftertreatment systems. Nernex NOx sensor electronics and software are designed to provide accurate exhaust-gas data to the vehicle control system, supporting proper Selective Catalytic Reduction (SCR) operation and continuous monitoring of NOx emissions.
As an outlet / downstream NOx sensor, the Nernex 20.220341 measures NOx concentration after exhaust treatment. This feedback allows the vehicle's emissions-control system to evaluate SCR effectiveness and monitor NOx reduction during real-world vehicle operation.
