The LSM200 by Reventec is a military-grade capacitive coolant level sensor engineered for precision fluid measurement in demanding UAV and autonomous system environments. Built with hard anodised aluminum and fully sealed to IP68 standards, it offers robust performance under high-vibration conditions and extreme temperatures from -40°C to +125°C, with high-temp variants available. Its solid-state sensing mechanism delivers continuous 100Hz liquid level updates with no moving parts, ensuring reliability over long missions without maintenance-induced failure points.
Designed specifically for use with gasoline, AVGAS, JP-4, JP-8, and other defense-grade fuels and oils, the LSM200 features a 2-bolt mounting system and supports multiple output formats—analog (0–5V), CAN, or both—to integrate seamlessly with a wide range of avionics architectures. Its measurement accuracy remains unaffected by orientation, while MIL-STD-461G and DO-160F compliance certifies electromagnetic compatibility across defense-grade platforms. Custom lengths up to 450mm, connector configurations, and fluid calibrations allow the LSM200 to be tailored for mission-specific requirements in uncrewed vehicles and tactical systems.
