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 / pre-catalyst NOx sensor, the Nernex 20.220326 measures NOx concentration before downstream SCR treatment. This information helps the vehicle's aftertreatment controls determine appropriate DEF dosing and continuously manage exhaust emissions during vehicle operation.
