摘要/Abstract

摘要： 以工业电磁流量传感器最常采用的矩形鞍状励磁线圈为研究对象，从矩形平面励磁线圈在测量管道内磁场分布的解析算法出发，给出计算矩形鞍状励磁线圈在测量管内的磁场分布的一种折线近似算法.最后实验证明，这种折线近似法是一种简单可行的算法.

Abstract: This paper studies rectangular saddle excitation coil widely used in industrial sensors for electromagnetic flowmeters. An analytic algorithm is introduced to simulate the magnetic field distribution of plane coils inside pipes. An approximate folded line method is proposed to simulate the field of saddle coils. Experiments show that the folded line method is simple and feasible.

Key words: excitation coils, magnetic field distribution, electromagnetic flowmeter sensor
