The ways of reliable detection of metal inclusions by an eddy-current device
Source abstract
Abstract
The ways of processing signals of an eddy-current probe in the reception channel of an induction metal detector are considered. It has been shown that the reliable detection of a metal article is possible only if both orthogonal signal components on the phase plane from the article are detected. The ways of complex indication of the orthogonal signal components and elimination of noise caused by unbalance of the eddy-current probe are described.
