Abstract
The present invention refers to a compact and portable electronic system for detecting fissures, cracks and imperfections in ferromagnetic structures, which represents a proposal for saving power that is easily used to be started and operated. Said system is implemented in a monolayer PCI for detecting in real time geometric defects in ferromagnetic structures based on the magnetic memory method (MMM). The magnetic field sensor MEMS used in this system is operated under the Lorentz force principle and mainly consists in a resonant structure of silicon beams, an aluminum loop and a Wheatstone bridge with four piezo resistors of the p type. The system includes a graphic interface known as SAUMAT II designed in Delphi 7.net, which digitally processes the output of the PCI in a voltage mode through a commercial Data Acquisition Board and calculates the FFT of the value measured by the magnetic field sensor MEMS for clearly showing the presence of geometric defects in the analyzed sample. The invention results in a non-invasive technique for evaluating the state of the structure without affecting its functionality. The present invention is useful in the industry for preventing accidents and early detecting faults in pipelines and damaged weld.
