摘　　要：电容式传感器测量技术是现代飞机燃油油量测量的关键技术之一。随着现代航空技术的发展,对燃油测量精度的要求越来越高。通过对电容式传感器工作原理的介绍,分析出电容式补偿传感器的引入可消除温度变化带来的测量误差,提高飞机燃油测量系统的测量精度和可靠性。同时给出了补偿传感器在传统模拟式燃油测量系统和现代数字式燃油测量系统的应用。The measuring technique for capacitance sensor is one of the key technologies for modem aircraft fuel quantity measuring. The development of aviation technology demands increasingly higher accuracy for fuel measurement. Analysis of the operational principle of capacitance sensor in this paper shows the advan-tages of capacitance compensation sensor, i.e. it not only eliminates measurement errors generated by tem-perature, but also improves the measurement accuracy and reliability of aircraft fuel quantity measuring sys-tem. Besides, the paper describes the application of compensation sensor in traditional simulated fuel meas-uring system and in modem digital fuel measuring system.
