7515M

Regula 7515 is a compact device which consists of a controller constructed in metal body and two scanners used for non-destructive examination of the structure of electro-conductive nonferromagnetic and ferromagnetic materials.

The device is used together with Regula 7505М, expanding functionality of the latter.

Operation:

• After being demagnetized, magnetic tape is placed on the examined surface and fixed.
• One of the scanners chosen according to the type of material examined moves along the examined surface.
• The controller forms voltage pulses with preset parameters and feeds them to the scanner.
• Pulse current flowing in the scanner conductor forms an alternating magnetic field around it which induces eddy currents in electroconductive material of the examined object.
• The eddy currents trajectories and the corresponding magnetic stray fields display the lines of electric resistance caused by the form, size and location of defects on the examined object.
• Obtained magnetograms of magnetic stray fields are visualized by Regula 7505М for further processing and expert analysis.

• Automatic controller troubleshooting, control of battery charge provided that the charging unit is connected.

• Possibility to examine weak signals such as residual stress in surface layers of ferromagnetic and nonferromagnetic objects.

• Investigation of markings on data carriers made of aluminium alloys (silumin bodies of cylinder blocks and reduction gear assemblies, manufacturer aluminium plates, duraluminium bodies)

• Restoration of fully destroyed original VINs on ferromagnetic materials

• Surface examination of nonferromagnetic materials in oder to get information and (or) to prove the fact of VIN falsification

• Detection of welded joint defects in ferromagnetic materials and aluminium alloys as well as detection of weak signals in surface layers of ferromagnetic objects, e.g. residual (internal) stresses
