The NOx sensor used for catalyst management in vehicles with gasoline or diesel engines. The NOx sensor consists of a ceramic sensor element and an electronic control unit (ECU).
The NOx sensor measures the NOx concentration, air/fuel ratio (A/F ratio) and equilibrium oxygen partial pressure in the exhaust gas of combustion engines (gasoline and diesel)
- Independent R&D and production of chips
- Covering multiple series of car models
- Meet the requirements of stable sensor signals, high accuracy and long service life under various atmosphere environments during vehicle driving
