Abstract

"SENSOR DE CAMPO MAGNéTICO". A presente invenção refere-se a um sensor de campo magnético, especialmente para a medição do número de rotações de um componente rotativo de caixa de mudanças com uma sonda Hall (3), no mínimo um ímã permanente (4), uma caixa (2), sendo que a sonda Hall (3) encontra-se na área de influência do campo magnético do ímã permanente (4). A invenção tem o objetivo de criar um sensor de campo magnético que possa ser produzido de modo menos complexo. Para alcançar esse objetivo propõe-se que o ímã permanente (4) seja fixado na caixa (2). Uma vantagem decisiva dessa disposição consiste na resistência extraordinariamente alta e na baixa suscetibilidade para vibrações.
