Abstract： The array eddy current detection of cylindrical metal specimen can be completed by several probes composed of array coils arranged around the specimen. The array eddy current probe is composed of exactly eight coils and completes the detection of metal specimen under a certain spatial structure. An array eddy current testing system based on Zynq-7020 is designed to excite one or more coils with the help of 8 analog switches of the excitation channel. With the help of an 1-in-8 analog switch, 8 array coils can be acquired in time. The signal is extracted by digital phase sensitive detection algorithm. The test results show that the system can save, transmit and process the excitation signal and induction signal of the array probe and complete the test task of measuring the sensitivity of the array probe.
