<p>The proposed device for nondestructive testing of articles with dielectric coating on metallic surface by using high-frequency high-strength electric field contains a photographic camera wit a window for photosensitive film, a metallic electrode, which is installed at an insulator inside of the camera, a high-frequency oscillator, and additionally, a tube made of opaque material, which is installed in front of the camera window, and a pusher with a knob, which is coupled with the insulator of the electrode. The electrode is connected to the output of the oscillator. The pusher is designed for pressing the film, by the electrode, to the surface of the tested article. The camera window is closed by a light-tight blind made of insulating material.</p> |
