摘要：
FIELD: defectoscopy.SUBSTANCE: using: for acoustic impedance method of non-destructive testing of multilayer materials and products. Summary of the Invention is that the adjustable combined converter of the impedance flaw detector includes a body of a controllable combined converter, a contact element in contact with a controlled object, a radiating piezoelectric element with a balancing mass, and a receiving piezoelectric element. In addition, the body of the combined converter is equipped with a rod made of two parts – the upper and lower parts, rigidly connected by two elastic blocks consisting of flexible curved plates, with interlayer installed between them, connected with the possibility of adjustment by an adjusting screw with a nut. And also the upper part of the rod and the lower part of the rod are rigidly connected to the radiating and receiving piezoelements. Case of the combined converter is made with two side windows serving for quick replacement of both individual flexible curved plates and e
