Eddy current defectoscope FD-3
FILD OF APPLICATION
Defectoscope FD-3 allows to detect surface, subsurface defects such as cracks in
PRINCIPLE OF OPERATION
The principle of operation of defectoscope is based on eddy current method. The control
is performed by moving the transducer on the surface of detail.
Portable device FD-3 consists of pencil-type transducer and electronic unit. The output
voltage of the transducer, after processing in the electronic unit, is displayed. There are light (LED) and sound
indication of the presence defects.
The small size of transducer allows detect defects in inaccessible areas of complex
shape products, including the low-purity class of controlled surface, as well as under the insulating coating
(paint, plaster, etc.) with a thickness up to 8 mm. Defectoscope has a minimum of settings and adjustments.
The transducer has a wear-resistant working surface.
