This vibrator is used for non-destructive control in machine engineering, construction and metallurgy. It has a wide frequency range of radiated ultrasonic waves, a simplified device for generating electrical pressure, which has expanded capabilities for regulation of amplitude and frequency. The radiator consists of a regulable low-frequency generator of electrical pressure (1), to which is tuned an electrical coil (2), with a ferromagnetic core (3). The latter, via a medium (4), is in acoustic contact with the controlled object (5).
