Enhancing NH3 sensing performance of mixed potential type ...

Nov 01, 2019· The effect of sintering temperature on sensing performance of the sensor using ANO-SE to NH 3 was investigated in dynamic test system, as shown in Fig. 3a. Three sensors exhibit well response-recovery characteristic in the NH 3 concentrations of 100–400 ppm at 450 °C. The response signal is defined as ΔV (ΔV = V sample - V baseline, where V sample is the largest potential value in NH 3 ...

NOx Sensors - DieselNet

Abstract: Automotive NOx sensors are primarily of the amperometric type, with two or three electrochemical cells in adjacent first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. Commercial sensors, available from several suppliers, are used for the control of NOx adsorber and SCR aftertreatment.
