1. Core Positioning​ A key sensing component for automotive fluid systems, mainly used to monitor the pressure difference between two points (e.g., intake manifold & atmosphere, inside & outside fuel rail, before & after Diesel Particulate Filter (DPF)). It converts differential pressure signals into electrical signals and transmits them to the ECU or dedicated control system, assisting in regulating engine air intake, fuel injection pressure, and DPF regeneration timing. It prevents insufficient air intake, abnormal fuel pressure, or DPF clogging, and is compatible with the power and emission systems of fuel vehicles and new energy vehicles (e.g., hydrogen fuel cell systems).​ 2. Core Functions​ Accurate Differential Pressure Monitoring: Measurement range -10kPa to 100kPa (up to 500kPa for custom models), accuracy ±1% FS (full scale). Adopts MEMS (Micro-Electro-Mechanical Systems) sensor chip to real-time capture tiny differential pressure changes (minimum resolution 0.1Pa);​ Fast Signal Response: Response time ＜200ms, supports analog (0-5V/4-20mA) or digital (CAN/LIN bus) output, with communication delay ≤10ms with control systems;​ Fault Diagnosis: Generates fault codes (e.g., P0234 "Abnormal Intake Pressure", P2453 "DPF Differential Pressure Sensor Fault") when differential pressure exceeds safety threshold or sensor malfunctions, facilitating troubleshooting;​ Environmental Adaptation: PPS high-temperature resistant housing (withstands -40℃ to 125℃), IP6K9K protection rating, resistant to oil mist, vibration (10-2000Hz), and electromagnetic interference (EMC Class 3).​ 3. Core Advantages​ High Reliability: No performance degradation after 5 million pressure cycle tests, service life ≥5 years / 150,000 km;​ Comprehensive Compliance: Certified to IATF16949 and ISO 14001, meets RoHS, China National Emission Standard VI, and hydrogen fuel cell vehicle safety standards;​ Easy Installation: Provides threaded/snap-on installation interfaces, supports direct replacement of original equipment (OE) parts (e.g., same specifications as Bosch, Continental);​ Wide Compatibility: Compatible with engine intake systems, fuel systems, DPF/SCR emission systems, and hydrogen circulation systems of hydrogen fuel cells.​ 4. Adaptability​ Vehicle Coverage: Passenger vehicles (sedans/SUVs), commercial vehicles (heavy-duty trucks/light trucks/buses), new energy vehicles (BEVs/PHEVs/hydrogen fuel cell vehicles);​ System Adaptation: Adapts to intake manifold differential pressure monitoring, DPF/SCR differential pressure monitoring, fuel rail differential pressure monitoring, and hydrogen fuel cell stack inlet-outlet differential pressure monitoring. Customizable measurement range and signal protocol.​ 5.
