An Airplane Fuel Measurement System by Using Optic Fiber Sensors

摘要：

　　A new type optic fiber pressure sensor is designed by using the mechanism of optical fiber macro-bend loss,which is used in the airplane fuel measurement system to obtain fuel level and density.The ratio method of pressure is adopted in the airplane fuel measurement system to reduce the influence factors,which include the vertical acceleration of a plane,fuel density,the pressure in the tank,etc.A pressure demodulation circuit of high precision and a data processing algorithm of high reliability are designed for measurement system.The experiment shows that the fuel measurement system has the characters of stability,reliability and high accuracy.
