Aftertreatment System Diagnostic Solution

The 2272917 AdBlue Sensor employs quartz-based piezoelectric measurement with dual-channel urea concentration analysis. Multi-layer ceramic substrate ensures ±1.2% accuracy across -40°C to 120°C operational range. Corrosion-resistant PPS housing meets ISO 16750-4 chemical exposure requirements. Integrated temperature compensation maintains measurement stability during rapid SCR system temperature fluctuations. Modular design allows direct replacement without DEF tank disassembly. Sealed M12 connector complies with IP69K ingress protection standards. Active urea crystallization prevention through periodic self-cleaning cycles. Polyurethane-coated sensing elements resist DEF fluid degradation. Universal mounting bracket adapts to multiple SCR system configurations. Diagnostic feedback complies with J1939 protocol for real-time urea quality monitoring. Dual redundancy measurement channels ensure continuous operation during sensor maintenance. Optimized flow geometry minimizes pressure drop in DEF supply lines. Electromagnetic shielding prevents interference from high-voltage components.
