Reliable Eddy Current Testing Equipment for Continuous Steel Wire Rods

Reliable Eddy Current Testing Equipment for Continuous Steel Wire Rods

Eddy current weld testing is a non-destructive testing technique for detecting component defects by using the principle that the eddy current induced by the AC electromagnetic coil on the surface of the metal member encounters a defect. The oscillating current is generated in the conductive member by the excitation coil by the principle of electromagnetic induction, and the amount of change in the eddy current is measured by the detecting coil, thereby obtaining information on the component defect.

Using eddy current signal processing method and high performance DSP algorithm, the detection ability of micro-crack is as high as 0.05mm deep crack.

Using computer digital technology and "digital eddy current detection technology" to achieve high speed data processing capabilities, detection speed1-500m/min.  Adopting advanced technology can effectively suppress all kinds of interference signals.  It has waveform,amplitude,phase,X-axis and Y-axis signals and other display modes.

The professional "digital filerting" is adopted to effectively suppress the interference signal in the field and ensure the accuracy and stability of the detection.
