The LSM200-IP69K is a rugged coolant level sensor engineered specifically for defence UAV platforms. Designed to last, the sensor is constructed from hard anodised aluminium and is IP69K rated to protect against dust ingress, high temperatures and high pressure liquids.
Leveraging the latest advancements in capacitive sensing, the LSM200-IP69K utilises technology proven in established UAV and airframe platforms. The LSM200-IP69K offers powerful fluid monitoring with accuracies of ±1% of reading (±0.5% accuracy variants available) in a compact, lightweight device with sturdy 2-bolt mounting fixing. Reliable, real-time readings allow operators to optimise their mission with continuous fluid level measurement for serious range extension allowing UAV manufacturers to fly further for longer. Integrated electronics encased within the sensor head deliver analog, CAN or analog and CAN outputs without the need for external CPU processing. 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. With superior dependability in the most extreme conditions, the LSM200-IP69K is shock resistant, vibration tolerant and has a 2 bar differential tank pressure rating (up to 10 bar pressure ratings are available).
As a solid-state technology, the sensor is insensitive to orientation allowing for sensor fitment to fuel tanks at any angle, including inverted, for easy installation and access whilst maintaining high measurement accuracy. The LSM200-IP69K is factory-calibrated in the customer-specified liquid type so that it is ready for installation on arrival.
The LSM200 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.
EMC approvals for this device includes: MIL STD 461F Army Ground Limits: CS114, CS115, CS116, RE102, RS103, RS101, CE102, CS101, RTCA DO160F: Section 25 ESD Cat. A
Output options include:
- Analog 0-5V (typically calibrated 0.25V empty, 4.75V full)
- CAN and Analog 0-5V
- CAN only
The LSM200-IP69K is available in two accuracy specifications:
- ±1% accuracy of reading
- ±0.5% accuracy of reading
The LSM200-IP69K is manufactured with a flying lead as standard but can be customised to fit a range of connector types dependent on requirement, including MIL-DTL-38999 connectors.
