Introduction
The NOx sensor used for catalyst management in vehicles withgasoline or diesel engines. The NOx sensor consists of a ceramicsensor 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 theexhaust 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 accuracyand long service life under various atmosphere environmentsduring vehicle driving
