Abstract :
An electromagnetic online monitoring system is described. Present crack detection and online monitoring techniques are briefly summarized, and the eddy current method is discussed in further detail. Electromagnetic analysis for sensor development and optimization, laboratory experiments to verify the flaw detection and imaging system, and demonstration of hardware for the integrated online monitoring system are reported
