| Abstract: | In detection of corrosion in pipeline with insulation layer,the pulsed magnetic flux leakage(PMFL) technique has many advantages.One of finite element analysis softwares,comsol multiphysics,is used to simulate the sensors with different structure.A new pulsed magnetic flux leakage(PMFL)sensor with optimizated structure is proposed,which can detect the corrosion in pipeline with insulation layer.The experiment results show that the optimizated structure is successful,and it paves the way for quantitative analysis of defect information. |
