A low cost embedded hardware based multi frequency Eddy Current System has been designed and developed to detect cracks in metallic structures. It includes a constant peak alternating current source capable of operating at multiple frequencies for detecting surface and near sub-surface cracks in metals. Eddy Current Testing probes for different frequency ranges are also designed using the Numerical...
A cost effective PC based Eddy Current Testing System is designed and developed to detect surface cracks in non-magnetic metals. The developed system is composed of Constant Current AC Source for excitation of the probe; and demodulation circuitry for acquisition of the signal from the crack. Eddy Current Testing Probe is also designed using the Analytical Approach. Surface cracks were successfully...
An endeavor has been done to produce a cost effective Eddy Current Testing System. For this purpose, study was carried out on using the Improved Howland Pump as a constant current AC source for exciting inductive load transducer i.e. the Eddy Current Testing (ECT) probe. Experimental validation was performed by fabricating the constant current AC pump and using it for excitation purposes in the eddy...
