98D57004038000 is a high-precision aerospace temperature sensor, engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, designed for monitoring critical thermal zones in narrow-body aircraft like the Boeing 737 MAX and Airbus A320neo—including engine bays, hydraulic systems, and avionics compartments—during MRO and in-service operations.

Constructed with a corrosion-resistant Inconel probe and EMI-shielded aluminum housing (IP67 hermetic seal), it measures temperatures from -70°C to 350°C with ±0.5°C full-scale accuracy. It transmits data via a 4–20mA analog signal, features wide-voltage input (18–32V DC), and includes over-temperature protection for durability. Weighing 0.28 kg and measuring 65mm×42mm×25mm, it complies with FAA Part 25/EASA CS-25, enabling proactive thermal fault detection and reducing unplanned maintenance for commercial fleets.
