Cummins Sensors provide a whole solution package, enabling system integration while meeting critical regulations. Cummins provides sensors that support a multitude of critical components on your engine – from controlling the speed of the turbocharger to assisting the level of NOx taken into the aftertreatment system. Product Benefits: Quality Control Cost Effectiveness High System Accuracy ...



The NOx sensors 12, 14, 55, 57 tend to have a lower sensitivity to NO 2 which causes the sensed NOx amount to change with the ratio of NO 2 /NOx. Accordingly, this configuration accounts for this potential discrepancy. The NOx amount leaving the SCR catalyst 50 may be measured by the NOx sensor 57 and/or the NOx sensor 14.
