98D71203011000 is a high-reliability aerospace fuel level sensor, engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, tailored for fuel tank monitoring and MRO of narrow-body aircraft including the Boeing 737 MAX and Airbus A320neo.

Constructed from corrosion-resistant stainless steel 316L with an IP67 hermetic seal, it uses a capacitive sensing principle to measure fuel levels across a 0–2.2m range with ±1.5mm linear accuracy. It features built-in temperature compensation (-40°C to 120°C) for stable readings in variable tank environments, plus a single 4-20mA output (with optional redundant signal) that integrates with onboard fuel management systems via CAN bus. Weighing 0.45 kg and measuring 82mm×58mm×40mm, it complies with FAA Part 25 and EASA CS-25, ensuring reliable fuel inventory data to maintain short-haul fleet operational safety and efficiency.
