Eddy Current Bobbin Probe Performance Evaluation Parameters Experiment

Yang Jin

Abstract

In order to evaluate and compare the Bobbin probes which are used in heat exchanger tubes eddy c(?)rrent testing(ECT),eddy current bobbin probe performance evaluation parameters are introduced in this thesis, through analyzing the basic elements of the ECT results.With comparison experiment between SNFSC self-made and imported probes and analysis for the results of the experiment,we conclude the method of eddy current bobbin probe performance evaluation.Finally,we give the acceptance level of Bobbin probes(φ11 mm) which are used in 08×18H10T stainless steelφ16 mm×1.5 mm SG tube ECT.The conclusion provides the reference for probe performance testing and comparison.
