How a NOx Sensor Works: The Ruize Technology Explained

At the heart of every effective diesel after-treatment system is a sophisticated piece of technology: the NOx sensor. But how does it work? Huizhou Ruize Automotive Technology Co., Ltd. utilizes advanced electrochemical principles in its sensor design. Inside each Ruize sensor is a ceramic element with dual chambers. Exhaust gas enters the first chamber, where an oxygen pump cell measures and adjusts the oxygen level. The gas then flows into the second chamber, where a second cell uses a catalyst to break down NOx. By measuring the resulting change in oxygen, the sensor can calculate the precise concentration of nitrogen oxides. This data is vital for the Engine Control Unit (ECU) to manage the Selective Catalytic Reduction (SCR) system efficiently. As a high-tech leader, we are proud of the intricate science that drives our products. To learn more about our innovative sensor technology, visit www.rznoxsensor.com.
