Abstract

"SENSOR DE POSIçãO" Um sensor de posição sem contato detecta deslocamento relativo entre dois objetos. Uma fonte de fluxo magnético é fornecida por uma pluralidade de ímãs distintos determinados de maneira seletiva para produzir uma fonte de fluxo altamente configurável que é facilmente adaptada para deslocamento rotativo ou retilíneo. A interação dos campos de fluxo individuais gerados pelos ímãs distintos é controlada para produzir ambas, as relações linear e não linear, com relação a mudanças em deslocamento. Uma peça pólo de reunião de fluxo é otimizada dimensionalmente para integrar a pluralidade de campos de fluxo individuais direcionados para um sensor magnético.
