A NOx sensor is a sophisticated device designed to detect and measure the presence of nitrogen oxides (NOx) in the environment. These sensors play a crucial role in emissions control in various sectors, such as the automotive industry and power plants.

NOx sensors use advanced technologies to accurately detect NOx concentrations in the air. Common technologies include chemical, electrochemical, and light-beam sensors. Each type of sensor has its own specific operating principle, but all rely on the ability to detect and respond to the presence of NOx.

Once installed, the NOx sensor communicates measurement data to an emissions control system or on-board computer. This data is used to monitor and adjust the operation of the engine or an industrial process to minimize NOx production and comply with environmental regulations.

The accuracy and reliability of NOx sensors are essential to ensuring efficient emissions control and compliance with environmental regulations. They allow real-time assessment of the amount of NOx produced and the necessary corrective measures to reduce the negative impact on the environment and human health.

In conclusion, NOx sensors play a vital role in monitoring and controlling nitrogen oxide emissions, helping to preserve air quality and promote a healthier and more sustainable environment.

The AF sensor is also known as the NOx sensor control unit for emission control and is used before the catalytic converter (catalytic converter).
