摘　　要：本文通过对三段式差动电感变换器轴向磁场分布的研究 ,找出了其非线性的根本原因 ,并针对这个问题提出了一种新颖的差动式电感变换器的结构形式。实验测试证明 ,这种结构的变换器的线性范围较同样长度尺寸的传统三段式变换器宽 ,且灵敏度高、漂移小 ,精度能够达到要求 ,同时其结构和绕线工艺也较传统的三段式位移变换器简单 。Based on the analysis of the axial magnetic field of the three section differential displacement inductance transducer and its non linearity, a new type differential inductance transducer is described in this paper. Practical tests have proved that this transducer has higher sensitivity, wider linearity range than traditional ones of the same size. At the same time it has simple structure and techniques which can be put in batch production.
