[en] ELECTROMAGNETIC SENSOR FOR THE MEASUREMENT OF SPEED AND DIRECTION OF OCEAN STREAMS / [pt] SENSOR ELETROMAGNÉTICO PARA MEDIÇÃO DE VELOCIDADE E DIREÇÃO DE CORRENTES MARINHAS

BEATA ZOFIA FELCZAK DE BARRIOS GUNDELACH 03 January 2007 (has links)
[pt] Este trabalho examina a viabilidade de construção, utilizando tecnologia nacional, de um sensor eletromagnético de velocidade e direção de fluidos, sendo considerado o caso particular de correntes marinhas. O projeto do sensor e os problemas técnicos de produção são apresentados e discutidos, assim como as medidas efetuadas em um protótipo. Considerações gerais sobre o tratamento dos sinais fornecidos pelo sensor também são expostas. / [en] This thesis presents a study of the feasibility of industrial production of an electromagnetic sensor for the measurement of fluid flow, using national available technology. The project of a prototype is developed for the special case of marine currents. The problems concerning the project and its implementation, as well as the measurements obtained from the prototype, are presented and discussed. The sensor signals processing is also examined in its general aspects.
