DEVELOPMENT OF SMART EDDY CURRENT NONDESTRUCTIVE TESTING INSTRUMENT

Directing against the disadvantage of the complicated hardware and strict operation of traditional eddy current testing instrument, a set of smart eddy current nondestructive testing instrument was developed and the related software and hardware were designed. Current virtual instrument technology and the software using CVI platform of NI Company with function of PC control, data processing, communication and interface display were adopted. The instrument was more simple in hardware, convenient in debugging and lower in cost.
