2C90521G02 is a precision aerospace component compliant with AS9100D quality standards and FAA/EASA regulations, dedicated to aircraft engine lubrication systems.It acts as a high-performance engine oil pressure sensor, a core monitoring component for MRO replacement. It real-time detects lubricating oil pressure in key engine parts, transmits accurate pressure signals to the engine control unit, monitors oil supply status of bearings and gears, triggers timely alerts for abnormal pressure, prevents oil starvation or overpressure damage, and ensures stable lubrication under high-temperature, heavy-load operating conditions.Made of aviation-grade corrosion-resistant alloy with precision sensing elements, it resists oil erosion and vibration, working stably at -55℃ to 310℃. Weighing 0.09kg, it features compact structure, high sensitivity, standardized electrical ports and leak-proof sealing, enabling easy installation and reliable long-term operation. It is a critical component to guarantee lubrication system safety and overall engine operational reliability.
