Introduction 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 1.Short light-off time
2.Low heating power
3.Less dependent on exhaust temperature (conducive to the stability in different operating situations)
4.Double protection on the top of tube to confront impact
5.Good aging resistance
6.Anti-coating and anti-poisoning
7.Compact structure (high anti-vibration level)
8.Longer duration
9.Independent R&D and production for ceramic/zirconia oxide ZrO2 chips
10.Covering multiple series of car models.
11.Strong ODM/OEM capacity, cover multiple series of car models
