Abstract
Testiranje vrtložnim strujama je nerazorna metoda ispitivanja električki vodljivih objekata. Razvijena je digitalna sonda za testiranje vrtložnim strujama temeljena na ARM Cortex-M4 arhitekturi. Sonda je namijenjena ispitivanju svojstava i oštećenja cijevi, s posebnom pažnjom obraćenom na minijaturizaciju sonde radi mogućnosti umetanja u samu cijev. Za pobudu zavojnice koristi se pravokutni upravljački signal s definiranim spektralnim komponentama. Sonda se sastoji od digitalnog i analognog podsustava i pobudne zavojnice, a prema upravljačkom računalu potrebne su veze za serijsku komunikaciju i bipolarno napajanje. Sustav je testiran u rasponu od 4 do 50 kHz u kojem omogućuje praćenje impedancije zavojnice. Prikazane su linearne krivulje umjeravanja potrebne za povećanje točnosti mjerenja.
Abstract (english)
Eddy current testing is a non-destructive testing method used on electrically conductive materials. A digital eddy current probe has been developed based on ARM Cortex-M4 architecture. The probe's intented use is determining the qualities and defects of a tube, with special attention being given to miniaturization of the probe itself, so it could be placed inside the tube. The excitation signal is a square wave with defined spectral components. The probe consists of a digital and analog subsystem and a single coil, with external connections required for serial communication with the host PC and bipolar power supply. The system has been tested and found functional in determining the coil impedance in the 4 to 50 kHz range. Linear calibration curves have been found which are required for higher measurement accuracies.
