This paper deals with an ECT diagnosis system using network communication. This system consists of an inspection module, a computational m odule and a communication interface module which can visualize some inspection results from the inspection module with ECT and some analys is results from the computation module. Here, three modules are connected through network architecture and communicated each other. Moreov er, an operator can control interactively the inspection and computational modules in order to...

The underwater vehicle system to inspect a nuclear power plant has been developed. In this work, the function of position dete ction to show the moving vehicle's position to operators is proposed. This paper describes the new method using map matching th at consists of the cross-section shape data cutted by 3-D CAD data and the inner surface geometry measured by laser range find er. Finally, by the fundamental examination using the sensor unit, it was confirmed that the position was detected within 48mm....

Electro-Magnetic Induction Testing method is widely used in the industries. However, due to the deterioration of sensitivity by increase of Lift-Off (distance between sensor and test piece) and the limitation of penetration of magnetic flux into thick magnetic and conductive material such as carbon steel, its application is limited to comparative testing between sound and defective samples. The newly developed system enables the measurement of wall thickness and the detection of inner-surface defects ...

Eddy Current Testing (ECT) is widely used in the industries. However, ECT normally uses certain high frequency range, therefore its application is limited to detect surface- or near surface defects. Strength of the electro-magnetic flux decreases exponentially in penetrating into the samples, and its rate is a function of conductivity, permeability and thickness of the samples and the frequency in use. Therefore, conventional ECT is difficult to detect inner surface defects or measure the thickness of...
