Ammonia Sensor for Closed-Loop SCR Control

SENSOR NH3 EMF [mV] 042406B2 EMF. Figure 3. Water-oxygen emf difference as function of air humidity and A/F Increasing air humidity has two effects on the ammonia sensing emf. It lowers emf and changes the shape of A/F-dependence. In the range of A/F ratio between 20 and 50 the maximum emf variation observed is 15 mV at 0 g/kg, 5 mV at 20 g/kg and 9 mV at 60 g/kg. For comparison, a 15 mV ...

Cummins ISB fault 3582, NH3 sensor likely? : DieselTechs

Cummins ISB fault 3582, NH3 sensor likely? Ran into this guy today. Came in with an scr cat conversion efficiency code and I watched it go through a regen. Nox levels look good however the NH3 midbed sensor was hanging at around 900ppm for about 5 minutes after initialization. I'm spit balling here but after talking to a few other techs and googling around there appears to be an update on the ...
