The Model AS-LLE  is a miniature, single-point level sensor for detecting and alarming on liquid levels in tanks, reservoirs, sumps and gearboxes on commercial and military fixed wing and rotary aircraft. Unlike ordinary level sensor that installed through a tap point in a vessel and protrude both into and out from the vessel, the AS-LLE is designed to be installed within the vessel itself.  There are no external penetration points to leak or that require additional external space to accommodate their installation.  The AS-LLE can be used with most any liquid, including water, oil, hydraulic fluid, coolants, and more.  Its titanium construction ensures it is rugged, lightweight, and corrosion resistance.
