Remote Oil Level Sensor Improves Measurement in Difficult to Access Locations >>

Monday, 29 April 2013


SAN MARCOS (US) - 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 over 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, electricalgenerators, auxiliary power units and more.


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.


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


FCI’s aerospace pressure sensors are piezoresistive strain-gauge 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 calibrationfacilities.  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.

Fluid Components International is a global company committed to meeting the needs of its customers through innovative solutions to the most challenging requirements for sensing, measuring and controlling flow and level of air, gases and liquids.
