Introduction 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).
Features 1.Independent R&D and production of chips
2.Covering multiple series of car models
3.Meet the requirements of stable sensor signals, high accuracy and long service life under various atmosphere environments during vehicle driving
