Product Description

Product Description

The wide band oxygen sensor 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.

Product 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
