The 5WK9 7368 NOx sensor functions as a core component of the Selective Catalytic Reduction (SCR) system for diesel exhaust aftertreatment. It delivers NOx concentration signals to the SCR control system, which serves as a key data basis for DEF dosage calculation and injection control. This product is produced by Zhejiang Kreation Electronic Technology Co., Ltd., a manufacturer focusing on research, development and production of intelligent sensors and exhaust treatment components.
This sensor is designed for aftermarket replacement and system integration projects, suitable for commercial vehicle fleet maintenance, aftermarket parts distribution and small-batch system matching scenarios. It adapts to common diesel engine SCR systems and supports stable NOx concentration monitoring for exhaust treatment processes.
The sensor adopts electrochemical sensing technology to detect NOx concentration in exhaust gas. The sensing element generates electrical signals corresponding to NOx concentration, which are converted into standard output signals and transmitted to the engine control unit. This technology supports real-time NOx level feedback for the control system to adjust injection strategies.
The sensor adopts an aluminum housing and ceramic sensing elements. This structural design adapts to temperature fluctuations, vibration and corrosive components in exhaust environments, and maintains stable signal output during regular operation. The structural layout follows the installation dimensions of corresponding original specifications, supporting direct replacement in matching models.
Designed as a replacement for original NOx sensors of corresponding specifications, this product is compatible with SCR systems used in vehicles equipped with sensing solutions from brands including Bosch, Continental, Denso, and NGK. It applies to both diesel and gasoline engine exhaust aftertreatment systems with corresponding interface specifications.
The sensor follows the interface and communication protocol specifications of corresponding original parts, supporting plug-and-play installation. This design reduces installation and debugging time for maintenance technicians, and shortens vehicle downtime during replacement operations. No additional programming or adaptation is required for matching models.
The sensor provides accurate NOx concentration data to support stable operation of SCR systems, assisting vehicles and industrial equipment in meeting local emission regulation requirements. It helps commercial operators avoid penalties and inspection failures caused by non-compliant exhaust emissions.
By delivering real-time NOx data to the engine control system, the sensor supports adjustment of combustion and DEF injection parameters. This function assists in optimizing combustion efficiency and reducing unnecessary DEF consumption, supporting controlled operational costs for fleet and industrial equipment management.
As an aftermarket alternative to original specification sensors, this product provides corresponding functions at a competitive price point. It reduces procurement cost for replacement parts for fleet maintenance and parts distribution businesses, while maintaining matching system performance.
