FEATURES EDDY-2K

EDDY-2K

EDDY-2K consists of the following modules:

•     electronic module DAMI-C09;
•     positioning device for shafts;
•     mechanism for automatic feed/retraction of the converter and marking unit to the product;
•     automatic signaling unit ASD (three-color signal lamp);
•     control unit and feedback with PC;
•     personal computer;
•     software disk.

EDDY-2K implements low-frequency eddy current methods based on recording changes in the electromagnetic field of eddy currents induced by an exciting coil in an electrically conductive test object depending on changes in the specific electrical conductivity of the material.The excitation pulse generator (EPG) voltage is supplied to the excitation coil of the eddy current transducer (ECT) with a frequency of 7 kHz, resulting in the excitation of eddy currents in the tested material.
The amplitude of the excited eddy currents is directly proportional to the specific electrical conductivity of the material, which in turn depends on the structure of the controlled object. The signal received from the measuring coils of the eddy current probe is analyzed using the amplitude-phase method. During adjustment, the amplitude-phase plane is rotated by a fixed angle in order to eliminate the influence of the transducer positioning and the roughness of the test object. The result of processing the received signal from the object under study is displayed on the computer screen (when operating in automatic mode) or on the screen of the DAMI-C09 electronic unit (when operating in manual mode) in graphic form, and when the set response threshold (set by the strobe) is exceeded, an automatic defect alarm signal is generated.
