Ammonia Sensor for Closed-Loop SCR Control

NH3 GAS CONCENTRATION [PPM] 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 …
