Unmanned air vehicle with wall thickness measurement sensor, retrofit kit with corresponding wall thickness measurement method and wall thickness measurement sensor for unmanned air vehicle

摘要

It provides an unmanned air vehicle for measuring the wall thickness of a structure. Such an unmanned aerial vehicle may be an intrinsically safe unmanned aerial vehicle, and may include an arm with an electromagnetic acoustic transducer (EMAT) connected to one end of the arm, and the power and control assembly may be connected to the other end of the arm as a counterweight. have. The power and control assembly can include an activation device for the EMAT, such as a proximity sensor. The EMAT can be connected to a spring compressed according to a force perpendicular to the wall being measured to prevent excessive force from being applied to the structure and the EMAT. Also provided is a method for measuring wall thickness using an unmanned aerial vehicle and a retrofit kit for an unmanned aerial vehicle.
