ED-520Me Portable Eddy Current Test Instrument

Flaw detection and sorting of non-magnetic materials

Applications

The Centurion NDT ED-520 eddy current instrument is an electronic test device which will locate surface and near-surface discontinuities in non-magnetic materials.  It also finds surface defects in magnetic materials, where permeability is relatively constant throughout the test area.  In addition, the ED-520 will sort classes of materials according to such properties as hardness, alloy type, carbon content, heat treat condition, tensile strength, and grain structure (where these relate to changes in the magnetic and electrical properties of the test part). 

With proper standards, electrical conductivity may be evaluated.  This often relates to the tensile strength of many aluminum and magnesium alloys.  The instruments can also be used to measure the thickness of thin, non-magnetic sheets, as well as conductive and non-conductive coatings (when used with suitable standards).

The ED-520 is widely used in military and commercial aircraft testing as well as process control, receiving inspection, research and maintenance.  Its compactness, ease of operation, and consistent precision make the ED-520 valuable for testing in foundries, heat treat shops, and manufacturing plants - wherever accurate data must be obtained quickly to establish fatigue of product reliability.
