磁致伸缩飞机油位传感器的电路设计

Circuit design of magnetostrictive fuel level sensor in airplane

本文根据磁致伸缩液位传感器的测量原理,进行了磁致伸缩油位传感器的电路设计,对燃油密度变化造成的误差进行了温度补偿。该方法可以使燃油液位测量精度得到很大改进,有一定的实用性和先进性。

In this paper, based on the measurement principle of the magnetostrictive liquid level sensor, a circuit for the magnetostrictive fuel level sensor is designed; and a method of temperature compensation is developed to modify the error caused by the changing of fuel density. This practical and advanced method greatly improves the precision of fuel level measurement.
