Abstract
A device for inspecting clamping means, including an electromagnetic ultrasonic transducer including a winding for generating pulsed eddy currents on the surface of a clamping element, built into a system for generating a magnetic field including a cylindrical magnet arranged above the winding with the axis of rotation thereof coinciding with the axis of the winding and a magnetic circuit surrounding the magnet and the winding to guide the generated magnetic field so that the field lines pass obliquely towards the axis of the coil through an interface plane with the clamping element, opposite the winding, the interaction of the field lines and pulsed eddy currents being suitable for simultaneously generating longitudinal and transverse ultrasonic waves in the clamping element.
