The LSM500-38999 is a precision-engineered capacitive liquid level sensor developed for defense-grade UAV fuel systems. Constructed from anodized aluminum and featuring a 5-bolt configuration with an integrated MIL-DTL-38999 connector, the sensor ensures secure plug-and-play installation across demanding airborne environments. Designed to meet MIL-STD-461G and RTCA DO160F standards, it delivers stable high-fidelity readings in extreme vibration, shock, and temperature conditions ranging from -40°C to +125°C, with optional extended operation to +150°C.
This IP68-rated unit provides continuous solid-state sensing and supports analog (0–5 V), CAN, or combined outputs, eliminating the need for additional signal processing hardware. Its accuracy of ±1% or ±0.5% for higher-grade variants enables precise fuel management, supporting longer flight durations and improved system reliability. Custom-built to 700 mm and compatible with a wide range of aviation fuels including JET-A, JP-4, and JP-8, the LSM500-38999 ensures consistent performance for defense UAV operators seeking mission-ready fluid monitoring solutions.
