Product Description
Product Introduction
This Exhaust Temperature Sensor WG1034121033 is an OEM aftertreatment monitoring component for heavy-duty diesel trucks (e.g., Sinotruk Howo, Weichai WP series). It features a precision thermocouple sensing element, a high-temperature resistant metal probe with standard metric threads, a flexible heat-resistant wiring harness, and a waterproof electrical connector. Engineered to accurately measure exhaust gas temperatures in the aftertreatment system (e.g., before/after DPF, SCR), it is manufactured to strict OEM specifications to ensure reliable performance in high-temperature, corrosive, and high-vibration exhaust environments.
Core Function
-
Precision Temperature Measurement: Accurately detects real-time exhaust gas temperatures and transmits data to the ECU, enabling precise control of the DPF regeneration and SCR NOx reduction processes.
-
Emissions Compliance: Provides critical input for the aftertreatment system to maintain optimal operating temperatures, ensuring compliance with strict emissions regulations (e.g., Euro V/VI, China VI).
-
System Protection: Triggers protective measures if exhaust temperatures exceed safe thresholds, preventing damage to the DPF, SCR catalyst, and other aftertreatment components.
-
Durable Construction: The high-temperature resistant probe and heat-resistant wiring harness withstand extreme exhaust temperatures (up to 850℃) and corrosive gases, ensuring long service life.
-
Perfect Compatibility: Strictly adheres to OEM design standards, ensuring it matches the original sensor’s thread size, signal output, and electrical requirements for full system compatibility.
