Dinex Particulate Matter (PM) Sensors are precision aftertreatment components that monitor the health and performance of the Diesel Particulate Filter?providing early warning of filter failure before it leads to costly damage or EPA non-compliance.;;The PM sensor is positioned downstream of the DPF and continuously monitors exhaust soot levels. When the DPF begins to fail or has been compromised?through ash loading, substrate cracking, or coating degradation?the PM sensor detects elevated particulate levels and signals the engine management system. This early warning capability helps prevent downstream component damage and avoids emissions violations.;;Dinex PM sensors are built to OE quality standards, validated by our Global Test Center, and engineered for precise, stable readings across the full range of operating temperatures and exhaust conditions encountered in Class 6-8 truck and bus service. Our range covers EPA 10-21 systems across all major vehicle platforms.;;As part of the complete Dinex aftertreatment sensor portfolio?which includes NOx sensors, temperature sensors, and pressure sensors?PM sensors allow you to source all your aftertreatment sensing needs from a single trusted supplier. This simplifies purchasing, ensures consistent quality, and reduces the complexity of keeping your aftertreatment systems running at their best.
