Eddy current detecting instrument EMS2003

Detailed product information:

EMS-2003, a smart magnetic memory/eddy current detecting instrument, is a new generation non-destructive testing (NDT) instrument with advanced microelectronic, computer, magnetic memory and digital eddy current detecting techniques. The 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 on it leakage magnetic field arises. At the places of defects or internal stress relative concentration the metal magnetic conductivity is in possession of minimum value, and the tangent component of its magnetic field is in possession of maximum value, and therefore the sign of the normal component is changed and its value is zero. When the normal component of magnetic field on the surface of the component is detected by means of transducer scanning, the stress concentration areas can be determined and accordingly the possibility of existing defects in ferromagnetic components can be indirectly estimated from its. At the same time the instrument has the digital eddy current detecting function and can be applied to the detecting of cracks and the depth of cracks in the weld with anticorrosion layer and its base material.

With EMS-2003 smart metal magnetic memory/eddy current detecting instrument a new and quick detecting for stress concentration caused by material discontinuity (defects) of the equipment in service will be carried out and early diagnostic results of equipment fatigue damage given out. The instrument is equipped with various different shapes of transducers and meters for length measurement to meet inspection requirements of different shapes of components and so can be applied to NDT of boiler pressure vessels, pipes, blades, bearings, rails, gears, welds as well other ferromagnetic metal components. The magnetic memory/eddy current detecting function of the instrument can be switched each other according to detecting requirements at will.
