Electrochemical oxygen sensor ZS-ST-01

zirconiapercent level

Cubic switch type oxygen sensor ST is also called as four-wire oxygen sensor, it is a planar 2-state λ=1 sensor of ZrO2 (Nernst-principle) with an integrated heater. The sensor contains 4 wires, in which two wires are for heaters, the other two wires are for transmitting voltage signals. Features ▪ Independent R&D and production of chips ▪ 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 9±1.5Ω • Operating voltage 12-14V • Maximum heating current 1.0A • Operating temperature / Exhaust gas temperature <930°C • Measuring the range of air fuel ratio 0.97~1.10 • Light-off time <15S • Lifetime 5 Year/100000km Applications • Engine management – Gas engines • Three Way Catalyst (TWC) Check – Vehicle Three Way Catalysts – On-Board Diagnostic System (OBD)
