Regula 7516 is a portable complex in a protective case. It comprises a magnetic powder visualizer, an electrochemical etcher, an eddy-current detector, auxiliaries and consumables, an optical probe with an oblique light source.
The complex can be used either as a separate device for non-/destructive examination of metal surface, or together with Regula 7505М expanding functionality of the latter.
The visualizer is intended for visualization of structural and relief inhomogeneity of material (e.g. internal stress zones, zones of local thermal effects, ferromagnetic materials, welded joints, surface defects) without removing varnish-and-paint coating.
Excitation of magnetic stray fields above the object surface. The magnetic stray fields display internal structural inhomogeneity of the material.
Magnetic powder visualization of magnetic stray fields of the object.
Eddy-current detector — a remote eddy-current sensor and a measuring indicator. The detector is intended for indication of structural inhomogeneity of material (welded joints, alterations of metal thickness, the layer of varnish-and-paint coating and zones of local thermal effects) without removing varnish-and-paint coating.
Excitation of the electromagnetic field of eddy currents in the examined area of the object. The eddy currents display internal structural inhomogeneity of the material and the object geometrics.
Indication of interaction parameters between the electromagnetic field of eddy currents and the electromagnetic excitation field.
