Abstract
U ovom radu proučene su metode ispitivanja nemagnetskih metalnih materijala metodom vrtložnih struja. Dan je pregled radova na temu induktivnih senzorskih sustava te je projektiran i izveden induktivni senzorski sustav za ispitivanje aluminijskih šipki. Sustav se sastoji od odašiljačke zavojnice, prijemnih zavojnica u diferencijalnom ili apsolutnom spoju, sklopovlja za prilagodbu i analognu obradu signala, digitalnu akviziciju te digitalnu obradu signala u razvojnom okruženju Matlab na osobnom računalu. Ispitano je nekoliko različitih konfiguracija senzora u frekvencijskom rasponu od 20 do 500 Hz. Kao najosjetljivija konfiguracija se pokazao diferencijalni spoj zavojnica postavljenih okomito na os ispitivane šipke. Prilikom usporedbe transimpedancije izmjerenih za punu šipku i šipku s umetkom, postotna promjena modula transimpedancije je iznosila 8,42%, a promjena faze 7,13°.
Abstract (english)
In this thesis eddy current testing methods for non-magnetic metals were studied. An overview of literature on induction sensors was given and a prototype of the induction sensor for aluminium rods testing was designed. The sensor consists of a transmitter coil, differential or absolute receiver coils, analog signal processing circuitry, digital acquisition and digital signal processing in Matlab on a personal computer. Several sensor configurations in the frequency range of 20 to 500 Hz were tested. Differential coils perpendicular to the axis of the examined rod proved to be the most sensitive configuration. When comparing the transimpedances measured for the solid rod and the rod with the insert, percentage change in transimpedance amplitude was 8.42% and change in phase 7,13°.
