Selective Catalytic Reduction Thermal Component

The 4326831 EGT Sensor utilizes nickel-chromium thermocouple alloys with triple-layer magnesium oxide insulation for 0-1000°C operational range. Precision-cast 304 stainless steel housing provides chemical resistance in urea-based SCR environments. Integrated signal amplification meets ISO 11898-2 CAN bus specifications. Vibration-dampened probe design withstands 28G shock loads across 15-2500Hz spectra. Thermal isolation barriers prevent heat transfer to electronic components. Multi-stage EMI filtration exceeds CISPR 25 Class 5 requirements. Optimized thermal response time of 380ms ensures dynamic temperature tracking. Corrosion-resistant M12 connector with gold-plated contacts achieves IP67 environmental protection. Active cold junction compensation maintains ±1.5% accuracy from -40°C to 130°C ambient conditions. Modular mounting system adapts to both pre- and post-SCR catalyst positions. Continuous self-monitoring detects sensor drift and harness connectivity issues.
