Nox sensor technology from Autolin
Autolin has been focusing on applying advanced technology to improve the quality and stability of Nox sensors. Technology creats quality. Every Nox sensor will under a series of strict test. Now our Nox sensors covering many brands as Mercedes, DAF, VOLVO,Scania, Man, Renault, BMW, ISUZU,HINO, HYUNDAI etc.
contains other products and information you need, so please check it out.
Nox sensor from Hubei Autolin technology use Taiwan newest chips and technologies.Every Nox sensor will be under a series of test before brought to the market.Let us explain our products features and test through the following below:
Product Features
⚫ NOx measurement range: 0-1500 / 2000 / 3000 ppm
⚫ O2 measuring range: 0 – 21 %
⚫ Maximum exhaust gas temperature: 800 ℃
performance standard
Start Time
The characteristic start-up time of the nitrogen and oxygen sensor is less than 120s.
| Testing items | Symbol | Nox sensors | Durability Test |
| Respinse time of NOx | τ(33%-66%)Nox | <1300ms | <1650ms |
| τ(66%-33%)Nox | <1300ms | <1650ms |
Response time
When the NOx concentration in the gas measured by the sensor changes from 0 to a certain value, the time required for the sensor to output the final value from 33% to the output final value of 66%;
And after the NOx concentration in the measured gas changes from a certain value to 0, the time required for the sensor to output 66% of the initial value to 33% of the initial value.
The response time is <1300ms before leaving the factory, and <1650ms after the durability test.
| Testing items | Output data | Maximum error from factory |
Maximum error after Durability test |
| Volume fraction | 0-3000ppm | ±10ppm(≤100pm) | ±12ppm(≤100pm) |
| ±10%(>100ppm) | ±12%(>100ppm) |
ESC/ETC cycle test
Stability working condition: The difference between the measured value of the German mainland sample at the working point is about 10ppm, and the measurement consistency is good.
Stability cycle: Compared with the NOx sensor of the German mainland brand, the measured concentration error is -2.45% to 2.68%.
Transient working conditions: The measured values at most working points are basically the same as those of the German Continental brand samples, and the measurement consistency is good.
Transient cycle: Compared with the German Continental brand NOx sensor, the measured concentration error is -2.85% to 3.68%.
