Urea Quality Sensor

Urea Quality Sensor(UQS) contributes to enhance the functionality of the Urea-SCR system, which is indispensable system for detoxifying NOx exhaust from large diesel engines of trucks, construction and agricultural machinery, moreover becomes increasingly prevalent.
The urea quality sensor detects the urea level, temperature, and concentration of the SCR system, and sends it to the engine controller through standard CAN messages.
The SAIC winter test will be completed in January 2021.
It has been mass-produced in several OEMs, and orders reached 10,000 sets in 2021.

Product Features:

1. Completely independent development, continuous improvement, low cost
2. Adopting the lagging solution, easy maintenance and low after-sales cost
3. reliable quality
4. Can realize customer customization requirements
5. The signal adopts high-frequency acquisition, taking into account the accuracy and responsiveness, and the temperature is corrected in the full range
6. Vibration, bubble interference, zero liquid level and other complex working conditions correction to prevent false alarms
