摘　　要：文中阐述了差胀涡流传感器的工作原理以及影响性能的几个重要关系 ,介绍了一种有效的线性化方法 ,使线性范围增加 ,线性误差减小 ,并分析了影响传感器温度漂移的主要因素 ,提出一种减少温度漂移行之有效的方法 ,并给出根据该方法得到的温漂试验结果。This paper describes the principle of eddy current sensor for measuring differential expansion and several important relations influencing performance, and introduces an effective linearizing method that can enlarge measuring range and decrease linearity error. The major factors that affect the temperature drift of eddy current sensors are analyzed. After theoretical analysis, an effective technique to cut down temperature drift is proposed.And the experimental results for temperature drift according to the said technique are also presented.
