Metal Magnetic Memory Analysis - NDT EMS-2000C

A smart metal magnetic memory testing instrument with advanced microelectronic, computer, metal magnetic memory analysis techniques for stress concentration inspection of in-service ferromagnetic components, welds, tubes etc.

EMS-2000C, a smart metal magnetic memory testing instrument, is a new generation non-destructive testing (NDT) instrument with advanced microelectronic, computer, metal magnetic memory techniques. Experiment proves that under the action of the alternative loading, the normalization phenomenon of the magnetic domain occurs at the places containing defects and inclusions in in-service ferromagnetic components, and leakage magnetic field arises on it. At the area where there has internal stress concentration, the metal magnetic conductivity value is the minimum and the tangent component value of its magnetic field is the maximum, and therefore the sign of the normal component is changed and its value is zero. The stress concentration areas can be located by detecting the normal component of leakage magnetic field on the surface.

Inspection settings for different applications can be stored in files and simply called up when needed.
