dc.description.abstract | Princip rada elektromagnetnih (EM) senzora brzine ili protoka se zasniva na Faradejevom zakonu indukcije. Kretanje provodne tečnosti kroz magnetno polje senzora indukuje na krajevima elektroda koje su u kontaktu sa tečnošću napon proporcionalan brzini kretanja tečnosti. U opštem slučaju, veličina napona je rezultat integracije vektorskog proizvoda nelinearnog polja brzina i nelinearnog magnetnog polja. Za potrebe ispitivanja osetljivosti EM senzora, od interesa je poznavati raspored magnetnog polja koje generiše uređaj. Takođe, potrebno je definisati koji uslovi, koji se mogu javiti u eksploataciji, utiču na oblik indukovanog magnetnog polja a samim tim i na pokazivanje samog uređaja. U ovom radu predstavljeni su rezultati ispitivanja magnetnog polja ravnog EM senzora brzine, sprovedenih u laboratoriji Građevinskog fakulteta, Univerziteta u Beogradu. | sr |
dc.description.abstract | The operating principle of the Electro Magnetic (EM) velocity, or flow meters is based on the Faraday’s law of the induction. The motion of the conductive fluid through the magnetic field of the sensor generates, on the electrodes, the voltage proportional to the flow velocity. In general, the output voltage value is a result of the integration of the non-linear flow field and non-linear magnetic field. In order to assess the sensitivity of the EM probes, the magnetic field distribution is needed. Also, it is required to determine which operational conditions can affect the distribution of the induced magnetic field, and thus the sensor’s output voltage. In this paper, results of the laboratory analysis of the magnetic field of the flat EM velocity meter are presented. Laboratory tests were performed at the Faculty of Civil Engineering, University of Belgrade. | sr |
