4384578 EGT Sensor | Cummins SCR Thermal Monitoring Component

4384578 EGT Sensor for Cummins SCR Aftertreatment Systems

Dual-Voltage SCR Thermal Monitoring Solution

The 4384578 EGT Sensor integrates platinum-resistance thermometry with three-stage ceramic encapsulation for 0-1000°C measurement stability. Forged aluminum-silicon alloy housing provides 12V/24V system compatibility with IP69K ingress protection. Multi-layer EMI shielding exceeds CISPR 25 Class 5 requirements for electrical interference resistance. Dual-element redundancy ensures continuous temperature monitoring during SCR system regeneration. Thermal barrier coating withstands 80°C/sec temperature gradients in exhaust streams. Vibration-resistant construction absorbs 28G shock loads across 15-2500Hz frequency ranges. Universal M20x1.5 thread configuration adapts to multiple exhaust pipe diameters. Automatic temperature compensation maintains ±0.95% accuracy from -40°C to 145°C ambient conditions. Self-diagnostic functionality detects probe degradation and signal anomalies. Oxidation-resistant tungsten-rhenium alloy extends service life in high-soot environments.
