Description

LSM200-38999

The LSM200-38999 is a solid-state, mil-spec liquid level sensor utilising the latest advancements in capacitive sensing technology for robust, dependable measurements with advanced accuracies of ±1% of reading (±0.5% accuracy variants available). Designed for real-time, reliable fuel and oil level measurement, the LSM200-38999 is ideal for defence UAV platforms that require powerful fluid level sensing in extreme environments.

Featuring a MIL-DTL-38999 connector fitted directly to the sensor head, the device is lightweight with an extremely small footprint. All control electronics are integrated within the sensor head allowing for analog 0-5V, CAN or analog and CAN outputs without the need for external CPU processing. The LSM200-38999 is made to order and is custom built up to a length of 450mm. Both the probe and electronics have a high operating temperature of -40°C to +125°C, with -55°C to +150°C temperature variants available. Certification to MIL STD 461G and RCTA DO160F available.

The LSM200-38999 is a solid-state IP68 rated device with no moving parts and benefits from extreme accuracy in high vibration applications, shock resistance and operability across a wide temperature range. The sensor ­can be fixed to a fuel or oil tank at any angle, included inverted, whilst maintaining high accurate measurement which is one of the reasons why Reventec liquid level sensors have been adopted by a variety of UAV platforms.

Providing UAV operators confidence when it counts, the LSM200-38999 measures changes in the liquid level for accurate and reliable measurement ensuring that the fuel or oil stays within safe limits for platform operation. Real-time, accurate sensor information is crucial for managing UAV flight duration and particularly when efficient use of fuel is critical to extend UAV platforms’ range and mission capabilities.

The LSM200-38999 is well-suited to all common automotive and UAV fuel, oil and coolant types including; Gasoline, AVGAS, JET-A, JP-4, JP-8 and 50/50 Glycol. The LSM200-38999 is calibrated in the intended fuel or oil, rather than a control liquid, for superior accuracy.
