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 precise DEF/urea dosing and effective Selective Catalytic Reduction (SCR) of NOx emissions.
As an inlet / upstream NOx sensor, the Nernex 20.220325 measures NOx levels entering the SCR system. This information allows the vehicle's aftertreatment controls to determine the amount of DEF required and continuously monitor emissions-system operation during real-world driving.
