Abstract:
To the problems in the tube eddy testing, some improved ways are given by using a three-point probe matching the eddy instrument model ET-204 with low field voltage, and selecting a phase having the optimum singnal-to-noise ratio with impedance plane technique.The testing results show that the method possesses a jamproof capability for distant testing with high sensitivity.
