FCI - Model AS-LLS - Liquid Level Switch - Brochure

FCI Model AS-LLS is a no moving parts, ultra-reliable level switch which detects the presence or absence of liquid or interface at the sensing location. The AS-LLS level switch is directly installed into tanks, reservoirs, sumps and gearboxes on commercial and military aircraft, as well as spacecraft, vehicles and marine applications. The sensor uses FCI proven thermal dispersion technology to rapidly detect and to signal of a too low level or too high level condition in the installation.  Unlike mechanical level detection, the AS-LLS will not stick, clog or foul and no routine maintenance is required. It is small, compact and lightweight suitable for a broad range of application throughout the aircraft.
