1. Core Positioning​ A dedicated monitoring component for automotive air filter systems, installed at air filter inlet/outlet. It real-time monitors the pressure difference across the air filter; when the difference exceeds the threshold (indicating clogging), it sends signals to ECU or instrument panel, triggering an alarm (fault code/indicator light) to remind air filter replacement. This prevents engine power loss and fuel consumption increase caused by insufficient air intake, compatible with all fuel and new energy vehicles.​ 2. Core Functions​ Accurate Pressure Monitoring: Measurement range 0-5kPa (up to 10kPa for custom models), accuracy ±2%FS, capturing pressure changes from air filter clogging;​ Fast Alarm Response: Response time ＜300ms, triggering alarm immediately when exceeding threshold (e.g., 2.5kPa) to avoid delayed maintenance;​ Environmental Adaptation: ABS housing (withstands -40℃ to 120℃), IP6K8 protection, dust and vibration (10-2000Hz) resistant;​ Fault Diagnosis: Generates fault code (e.g., P0101) when sensor malfunctions, facilitating troubleshooting.​ 3. Core Advantages​ Strong Specialization: Designed specifically for air filter clogging monitoring, compatible with various air filter sizes;​ Easy Installation: Snap-on/threaded interface, direct OE replacement without pipeline modification;​ Compliant & Reliable: Certified to IATF16949, meets RoHS standards, service life ≥4 years/120,000km.​ 4. Adaptability​ Vehicles: Covers passenger (sedan/SUV), commercial (heavy/light truck), new energy (BEV/PHEV) vehicles;​ Systems: Adapts to all automotive air filter systems, customizable pressure difference thresholds.​ 5. Service Support​ Contact customer service for parameters (pressure difference-alarm curve, installation drawing) and adaptation list; free installation guidance provided.
