摘　　要：为了研究保温管偏心检测中的电涡流传感器探头线圈的性能,根据电涡流测距原理,采用有限元方法,利用软件对涡流传感器检测偏心进行仿真分析,研究了管道偏心时探头线圈阻抗的变化以及检测距离和管道材质改变时对探头线圈性能的影响。In order to research the performance of the eddy current sensor probe coil for detecting insulation pipe eccentricityin this paper, according to the principle of the eddy current distance measurement, simulating analysis of eddy current sensorprobe for the detection of eccentric is conducted by using the FEM and the ANSYS software. This paper studied the changes ofprobe coil impedance when the insulation pipe is eccentric and the influence on the performance of the probe coil when detec-tion distance and pipe material changed.
