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, helping regulate DEF/urea dosing and support effective Selective Catalytic Reduction (SCR) of NOx emissions.
As an outlet / downstream / post-SCR NOx sensor, the Nernex 20.220319 monitors NOx levels after exhaust treatment. This feedback allows the vehicle's emissions-control system to evaluate SCR effectiveness and continuously monitor NOx reduction during real-world operation.
