Abstract

"SISTEMA SENSOR DE POSIçãO". Um sistema sensor de posição de cilindro inclui um alojamento do cilindro que recebe de forma deslizante uma haste ou elemento de eixo. O alojamento do cilindro possui uma peça que recebe de forma deslizante o elemento de eixo. Uma primeira ranhura axial é formada no elemento de eixo, e um primeiro membro de magneto é montado na primeira ranhura. Uma segunda ranhura helicoidal é formada no elemento de eixo e espaçada afastada da primeira ranhura. Um segundo membro de magneto é montado na segunda ranhura. Um sensor de campo magnético é montado no alojamento do cilindro, de tal modo que o sensor gera um sinal de saída como uma função de uma distância relativa entre o primeiro e segundo membros de magneto, à medida que o segundo elemento se move em relação ao primeiro elemento. Preferivelmente, o elemento de eixo inclui um eixo cilíndrico central e uma luva cilíndrica oca montada sobre e recebendo o eixo. Preferivelmente, a primeira e segunda ranhuras são formadas em uma superfície interna da luva, e a luva e a peça de extremidade são formadas de material não ferroso.
