Eddy current flaw detector Tomographic 4.1. is intended to detect fatigue cracks on the surfaces of non-magnetic and ferromagnetic metals and alloys.

fig.2
Eddy current flaw detector provides testing of the plane and curved surfaces with radius of positive and negative curvature up to 20 mm.
Eddy current transducer VTP-2 provides operation in the frequency range from 1 to 10 MHz.
A set of overlay probes provides testing of parts made of (0,4 – 40)*106 cm/m electric conductivity materials.
Information about the current testing point is presented by position of the special cursor on the complex plane.
Change of the transducer incline from the normal to the testing surface within 0-15° will result in shifting of the cursor on the complex plane. The flaw detection will result in horizontal cursor shifting. The cursor trajectory is displayed on the screen (fig.1) There is also a possibility of A-scan processing, visualization and saving in the archive (fig.2).
Technical characteristics:
detection of at least 3 mm long cracks, having opening from 0.05 to 1 mm
angle of the transducer incline from the normal to the testing surface from 0-30°
gap between the transducer and testing surface is not more than 0.5 mm if the surface roughness is Ra 1,25 mm
