Abstract

''SENSOR DE DESLOCAMENTO PARA DETECTAR O DESLOCAMENTO RECìPROCO ENTRE OS PRIMEIRO E O SEGUNDO ELEMENTOS, E, PEçA POLAR MODELADORA DE FLUXO PARA UM POLO DE UM PRIMEIRO MAGNETO DE UM SENSOR MAGNéTICO DE DESLOCAMENTO'' Um sensor de deslocamento inclui um conjunto de magnetos tendo um alojamento montagem em um de primeiro e segundo elementos reciprocamente móveis. Primeiro e segundo magnetos são montados no alojamento de conjunto de magnetos de forma que o polo Norte de um magneto confronte o polo Sul do outro magneto, e vice versa. Os primeiro e segundo magnetos formam um espaço longitudinal entre eles. Uma peça polar modeladora de fluxo sobre cada um dos polos tem configurações para esculpir o fluxo magnético de franja no espaço longitudinal de maneira que a densidade de fluxo magnético no espaço longitudinal varie substancialmente de forma linear ao longo de uma linha no espaço longitudinal entre os polos confrontantes dos magnetos. Um conjunto sensor de campo magnético tem um alojamento para montagem com o outro dos primeiro e segundo elementos. Um sensor de fluxo magnético é montado no alojamento de sensor sobre a linha no espaço longitudinal entre os primeiro e segundo magnetos. Em uma concretização, cada uma das peças polares modeladoras de fluxo tem a forma de um pentágono em um plano de padrão de fluxo primário, formando uma face estreita confrontando o espaço longitudinal entre os primeiro e segundo magnetos. A face estreita de cada peça polar modeladora de fluxo é mais larga através do padrão de fluxo primário do que ao longo da extensão da linha no espaço longitudinal.
