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 inlet / upstream NOx sensor, the Nernex 20.220327 measures NOx concentration before downstream SCR treatment. The sensor is installed in the exhaust system near the turbocharger outlet on applicable Cummins-powered vehicles, where it provides the emissions data required by the aftertreatment control system.
