Abstract

The present invention relates to an oxygen concentration measuring device comprising: a sampling interface fluidly connected to a gas source to direct a sampled gas to be measured from the gas source into the oxygen concentration measuring device; the gas separation assembly is used for separating nitrogen-rich gas and oxygen-rich gas from the sampling gas, and the nitrogen-rich gas and the oxygen-rich gas are respectively led out from the first outlet and the second outlet; and the sensor assemblies are respectively arranged at the sampling interface, the first outlet and the second outlet so as to measure parameters of the entered sampling gas and the nitrogen-rich gas and the oxygen-rich gas separated from the gas separation assembly. According to the oxygen concentration measuring device, relatively accurate and low-cost measurement can be realized by utilizing simple and mature components, the detection is rapid and convenient, the reliability is high, and the airworthiness manual or standard requirements are met. In addition, the invention also relates to an oxygen concentration measuring method.

Description

technical field [0001] The invention relates to an oxygen concentration measuring device, which is particularly used for measuring the oxygen concentration of gas in a gas phase space in a fuel tank, and can be applied to the field of test of civil aircraft fuel tank inerting system. [0002] In addition, the present invention also relates to a measurement method for measuring the oxygen concentration. Background technique [0003] The aircraft fuel tank is the storage unit of aircraft fuel, and providing a certain reserve of fuel is one of the necessary conditions to ensure the normal operation of the aircraft engine. Therefore, the fuel tank plays an extremely important aircraft-level function. Due to the flammable and explosive characteristics of fuel, the safety design of fuel tank has always been one of the key aspects in aircraft design. [0004] Civil aircraft are usually equipped with an inerting system, which separates the bleed air from the gas source system into ...
