The principle and system of the eddy current array (ECA)technology is introduced,and the 8 channels eddy current array probes have been manufactured.The signal analysis method for multi-channel has been studied and solved.Through experiments,it has been proved that using ECA probes,the new type fuel elements can be tested quickly and throughly,and the testing a-bility can be as small as 0.03mm,which is as same as the single little sensors and the testing er-ror is below 0.01mm.The research results can be applied to the manufacture procedure of the fu-el elements directly,which will play an important part to the quality of the elements.
