This reliable exhaust temperature sensor is a core component of engine post-processing system. It real-time monitors temperature changes of discharged exhaust gas and feeds accurate data back to vehicle control unit. It assists exhaust purification devices to operate normally, optimizes engine working state and effectively controls emission output. Made of high-temperature resistant alloy materials with integrated sealing design, it can resist long-term thermal impact and exhaust corrosion, keeping stable service effect for long-distance vehicle operation.
