Abstract:
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 current testing system. As a result, through-hole surface cracks were successfully detected which proved the working of the Improved Howland Current pump as a constant current AC source. It is a valuable technique for exciting Eddy Current Probes.
