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 ▪ 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 Parameters • Operating Temperature: -40~105°C • Exhaust gas temperature: 200~800°C • Supply voltage 10.8~36V • Typical supply Current 600mA • Maximum heating current 20A • NOx measurement range / accuracy unit: 0 ~ 100 ppm - ±10[ppm] 100 ppm ~ 1500 ppm - ±10[ • Measuring range of oxygen concentration 0~21% • NOx Response time Ƭ33−66%: 1300ms • Light-off time: Nox < 100 s (fresh) linear A/F-ratio < 80 s (fresh) Applications • Lean burn engines (NOx trap) • Diesel engines (SCR catalysts, NOx trap, cl • On board diagnostics, OBD (gasoline and diesel engines)
