Measurement Solutions for Aircraft and More

A new video from FCI Aerospace highlights Remote Oil Level Sensing (ROLS) instruments that measure fluid level with greater accuracy and efficiency in hard to reach installations aboard commercial and military aircraft, as well as marine, space and other transportation vehicles.

FCI’s advanced level sensors feature a reliable, lightweight design for single or multi point sensing – ideal for oil and other fluids. FCI’s liquid level sensors and switches are designed for service in the harshest aerospace, military, and marine environments. 

ROLS sensors from FCI rely on its highly dependable thermal dispersion technology, with decades of proven field service. They are widely designed into systems and devices managing gearbox oil, hydraulic and coolant reservoirs, automation of sight gauge level, oil and fuel level detection and rotorcraft level and temperature detection.

With more than 40 years of instrumentation experience, FCI provides sensors, switches, and transmitters that are found in a wide range of high-reliability, mission-critical applications including commercial and military aircraft, space, vehicle, and marine industries. Major applications for FCI sensors include environmental control systems, engine and fuel controls, gearbox and avionics cooling, electrical generators, auxiliary power units and more.

Flow – Featuring no-moving-parts thermal dispersion technology, FCI’s flow sensors and switches have established an unmatched record of performance and reliability in the toughest applications. Typical uses include air flow switches and transmitters, coolant and hydraulic fluid switches and transmitters, fuel flow switches and transmitters and potable and gray water systems.

Temperature – Designed for a wide range of critical temperature measurement applications, FCI’s temperature sensors measure temperatures from –65ºF to 800ºF  (-54ºC to 430ºC) and can survive in temperatures from -85ºF to 1,000ºF (–65ºC to 540ºC). Applications include service in hydraulic and coolant fluids, environmental cooling systems, cabin air temperature control, and more.

Pressure – FCI’s aerospace pressure sensors are piezoresistive strain-gage type sensors fabricated with advanced silicon processing techniques common in the       semiconductor industry. Typical applications include hydraulics, ECS, coolant systems, lubrication, and fuel systems.

FCI’s proven thermal dispersion sensing technology provides reliable flow and liquid level measurement in extreme temperature, high vibration, and dirty environments. Thermal dispersion technology features direct mass flow measurement with a no-moving parts design, which is inherently reliable and features built-in temperature compensation. It is simple to install, requires virtually no maintenance, and offers long-life for high total installed value. 

FCI calibrates its own air flow and liquid level instruments. It operates one of the industry’s leading flow analysis, modeling, and calibration facilities. All laboratory equipment is National Institute of Standards (NIST) traceable, as well as ISO 9001:2008 and AS9100 certified. The laboratory also meets MIL-STD-45662A and ANSI/NCSL-Z-540 requirements. The company’s laboratory has supported a large number of leading-edge development programs, including flight test sensors for the F22 Raptor Fighter, the V-22 Osprey Helicopter, the Global Express Program, and others.
