NOx sensor for Scania NOX

The nitrogen oxide sensor, part number 5WK97400, monitors the concentration of nitrogen oxides within the exhaust gas stream of Scania engines. It serves as a key input for the selective catalytic reduction system by supplying data to the engine control unit, which then regulates the injection of urea-based fluid to convert nitrogen oxides into nitrogen and water.

This component is designed for use in Scania NOX systems. It facilitates the precise monitoring required to maintain emissions compliance and system efficiency. By providing accurate feedback on exhaust composition, the sensor allows the engine management system to adjust operational parameters effectively.

In heavy machinery and commercial vehicle exhaust systems, NOx sensors are positioned within the exhaust path to measure gas concentrations before and after the catalytic converter. This measurement is fundamental for the operation of modern post-treatment systems, ensuring that the chemical reduction process functions within specified parameters to minimize environmental impact.
