1、 Function of nitrogen and oxygen sensor:
- NOx measurement range: 0-1500 / 2000 / 3000ppm NOx
- O2} measurement range: 0 – 21%
- Maximum tail gas temperature: 800 ℃
- it can be used under the conditions of O2 (21%), HC, CO and H2O (< 12%)
- communication interface: can
2、 Application fields of nitrogen and oxygen sensors
- diesel engine exhaust emission SCR system (meeting National IV, V and VI emission standards)
- gasoline engine exhaust treatment system
- desulfurization and denitration detection and control system of power plant
3、 Composition of nitrogen and oxygen sensor
The main core components of NOx sensor are ceramic sensitive components (probe part) and SCU components (circuit board)
NOx sensor, referred to as NOx sensor, is used to detect the content of nitrogen oxides (NOx) in engine exhaust gas, such as N2O, NO, NO2, N2O3, N2O4 and N2O5. According to the working principle, it can be divided into electrochemical, optical and other principles of NOx sensors. Using solid electrolyte yttrium oxide doped zirconia (YSZ) ceramic material conductive performance of oxygen ions, special NOx sensitive electrode material selective catalytic sensitive performance of NOx gas, and combined with the special sensor structure to obtain the electric signal of NOx, finally using special weak signal detection and precision electronic control technology, The NOx gas in automobile exhaust is detected and converted into a standard CAN bus digital signal.
