Eddy-current magnetographing device Regula 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 electroconductive nonferromagnetic and ferromagnetic materials.

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

Functionality

• 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

Operation

1. After being demagnetized, magnetic tape is placed on the examined surface and fixed.
2. One of the scanners chosen according to the type of material examined moves along the examined surface.
3. The controller forms voltage pulses with preset parameters and feeds them to the scanner.
4. 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.
5. 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.
6. Obtained magnetograms of magnetic stray fields are visualized by Regula 7505М for further processing and expert analysis.

Special features

• 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.

Application
