Abstract
UREDAJ ZA MERENJE NIVOA TECNOSTI MERENJEM PROMENA KAPACITETNOSTI MERNE SONDE je napravljen tako sto je za mernu sondu upotrebljen koaksijalni provodnik (1), sto je dovelo do povecanja kapacitivnosti merne sonde po duznom metru i na taj nacin minimizirao uticaj parazitne kapacitivnosti na merenje. Elektronika merne sonde je realizovana upotrebom jednog integralnog kola (70) u sprezi sa ostalim elementima na donjoj stampanoj plocici (15). Pretvarac naizmenicnog napona u jednosmerni je smesten na gornjoj stampanoj plocici (14) koja je sa donjom stampanom plocicom (15) povezana preko konektora (13). Obe stampane plocice su smestene u jednu kutiju - kuciste merne sonde (10), sto je doprinelo smanjenju gabarita celog uredaja, njegovoj jednostavnosti i kompaktnosti. Uredaj se jednostavno prikljucuje na mrezni napon 220V i pokazni instrument (ili neki drugi uredaj) preko visezilnog provodnika (12).A LIQUID MEASURING DEVICE BY MEASURING THE CAPACITY CHANGE OF THE MEASURING PROBE was made by using a coaxial conductor (1) for the measuring probe, which increased the capacitance of the measuring probe over a long meter and thus minimized the influence of the parasitic capacitance on the measurement. The electronics of the measuring probe were realized by using one integral circuit (70) in conjunction with other elements on the lower printed circuit board (15). The DC converter is located on the upper printed circuit board (14) which is connected to the lower printed circuit board (15) via the connector (13). Both printed circuits are housed in a single box - the housing of the measuring probe (10), which contributed to the reduction of the overall dimensions of the whole device, its simplicity and compactness. The device is simply connected to the mains voltage 220V and the indicating instrument (or other device) via a multi-wire conductor (12).
