Abstract
An oxygen analysis system (OAS) for measuring, monitoring and recording oxygen concentration in aircraft fuel tanks. The OAS has a rack support structure installed in an aircraft cabin with a plurality of oxygen analyzer devices mounted in the rack support structure. Each oxygen analyzer device has an oxygen sensor to measure oxygen concentration in gas samples continuously drawn from sample locations in aircraft fuel tanks and at an aircraft NGS ASM exit. The OAS further has a plurality of valves, a supply of calibration gases, a supply of purge and operating gases, and a power distribution assembly, all coupled to the rack support structure. The OAS further has a transport tubing assembly, a plurality of fuel tank gas sampling ports, an NGS ASM exit gas sampling port, a drain manifold assembly, and a data acquisition and recording system having a user interface software to monitor and control the OAS.
