The NOx Sensor-5WK9 7372 is an essential component in the diesel vehicle urea Selective Catalytic Reduction (SCR) system for post-treatment of nitrogen oxide reduction. By separating NOx into nitrogen and oxygen through a catalytically active electrode, it can simultaneously measure and discharge NOx, enabling rapid and accurate detection of NOx concentration levels in gases.

Overview


This NOx Sensor leverages non-dispersive infrared (NDIR) technology to deliver precise, interference-free nitrogen oxide measurements in the most challenging environments. Its ruggedized design and intelligent signal processing algorithms make it ideal for continuous emission monitoring in both mobile and stationary applications. By providing stable, drift-free performance, it empowers industries to maintain compliance while improving process efficiency and reducing environmental penalties.


Features


· Multi-Gas Detection: Simultaneously measures NO, NO2, and total NOx concentrations with cross-compensation for background gases.

· Anti-Interference Design: Proprietary optical filters and algorithms eliminate cross-sensitivity to CO2, SO2, and water vapor.

· Extended Warranty: 3-year industrial-grade warranty with optional extended service plans for mission-critical applications.

· Plug-and-Play Installation: Factory-preconfigured with adaptive calibration profiles for quick deployment across diverse equipment.

· Data Logging: Stores 6 months of operational data, including temperature, pressure, and diagnostic logs, accessible via USB or wireless interfaces.


Advantages


· Enhanced Durability: IP67-rated enclosure protects against dust, moisture, and vibration in off-road and marine environments.

· Energy Efficient: Low power consumption (2W max) enables integration into battery-powered or solar-driven systems.

· Remote Diagnostics: IoT-ready with Modbus RTU/TCP protocols for predictive maintenance and fleet management integration.

· Global Certification: Complies with CE, RoHS, and REACH directives, approved for use in 150+ countries.


Applications


· Heavy-duty diesel trucks and hybrid powertrains for on-board diagnostics (OBD) and emission reporting.

· Chemical processing plants to monitor reactor exhausts and comply with OSHA safety guidelines.

· Waste-to-energy facilities for optimizing incinerator combustion efficiency and minimizing NOx output.

· Agricultural machinery, including tractors and harvesters, to meet Stage V emission standards.
