Abstract

Patente de Invenção: <B>''SENSOR DE POSIçãO MAGNéTICO''<D>. A invenção refere-se a um sensor de posição magnético, no qual estão dispostos pelo menos dois elementos do estator em um campo magnético e uma sonda de campo magnético que se encontra no entreferro de medição entre os elementos do estator, em que está disposto um dispositivo que segue um objeto em movimento paralelamente ao plano gerado pelos elementos do estator. Um sensor de posição magnético, que é fabricado de forma simples e económica apresenta um elemento do estator e uma sonda de campo magnético dispostos sobre um elemento de suporte comum.
