Description

technical field [0001] The invention belongs to the field of measurement of lubricating oil parameters of aero-engines, in particular to an aero-engine lubricating oil liquid level and lubricating oil product measurement sensor. Background technique [0002] At present, there is no model product in China that can simultaneously realize the measurement functions of engine lubricating oil level and oil product. Capacitive lubricating oil level sensors are usually used to realize online measurement of aeroengine lubricating oil level. However, as the characteristics of the lubricating oil change, the measurement accuracy of this type of sensor will be greatly reduced; the measurement of lubricating oil is usually used Off-line detection method makes it difficult to realize real-time monitoring of oil products. Invention content: [0003] The purpose of the present invention is: this paper proposes an aero-engine lubricating oil level and oil integrated measurement sensor, wh...
