Introductions The wide band oxygen sensor LSU is a planar ZrO2 dual cell limiting current sensor with an integrated heater. It is used to measure the oxygen content and the λ-value of exhaust gases in automotive engines (gasoline and diesel). Its monotonic output signal in the range of λ=0.65 to air makes the LSU capable of being used as an universal sensor for λ=1 measurement as well as for other λ ranges. Features ▪ Short light-off time ▪ Low heating power ▪ Less dependent on exhaust temperature (conducive to the stability in different operating situations) ▪ Double protection on the top of tube to confront impact ▪ Good aging resistance ▪ Anti-coating and anti-poisoning ▪ Compact structure (high anti-vibration level) ▪ Longer duration ▪ Independent R&D and production for ceramic/zirconia oxide ZrO2 chips ▪ Covering multiple series of car models. ▪ Strong ODM/OEM capacity, cover multiple series of car models Parameters • Heater resistance 3.2±0.5Ω • Operating voltage 9V • Heater power steady state 10 W • Operating temperature / Exhaust gas temperature <930°C • Measuring range of oxygen concentration 0~21% • Measuring range of air - fuel ratio 0.7~+∞ • Light-off time <15S • Accuracy λ=0. 8 0.80 ± 0.01 • Accuracy λ=1.0 1.016±0.007 • Accuracy λ=1.7 1.7 ± 0.05 Applications • Engine management – Gas engines • Measurement and analysis processes – Flue gas measurement – Gas analysis – Wood Incineration
