Abstract:

   We devise a multi-channel eddy current instrument with a PCI2010 data acquisition card in the platform of Windows XP. We employ orthogonal decomposition to obtain phase angle and amplitude of an eddy current signal, and then present a technical proposal that PCI2010 card connects with eddy current testing circuit. Experimental results show that the instrument can detect the velocity up to 100 m/min for steel tubes. Its false alarm rate is less than 1% and its alarm failure rate is almost zero, higher than those in national standards.

Key words: Windows XP platform, PCI2010, orthogonal decomposition, eddy current instrument
