NOX sensor for DAF NOX

The NOX sensor, identified by part number 2139930, is a component within the emissions control system of DAF machinery. Its function is to monitor and measure the concentration of nitrogen oxides present in the engine exhaust stream. This data is transmitted to the engine management system, which uses the information to adjust fuel injection timing and other operational parameters to maintain compliance with environmental emission standards. The sensor is designed to operate within the exhaust system, where it is exposed to high temperatures and combustion byproducts.

This component is compatible with DAF NOX models. It serves as an input for the Selective Catalytic Reduction system, ensuring that the post-treatment process functions correctly. Proper operation of this sensor helps prevent the engine from entering protective modes or triggering diagnostic fault codes related to emissions performance. By providing accurate readings of nitrogen oxide levels, the sensor supports the overall efficiency of the exhaust aftertreatment system and assists in maintaining optimal engine operation according to the manufacturer specifications.
