Abstract

MONTAGEM DE SENSOR MAGNéTICO. A presente invenção refere-se a uma montagem de sensor que inclui primeiro sensor de campo magnetorresistente em um primeiro pacote montável na superfície, que mede primeiro e segundo componentes de um campo magnético projetado nos primeiro e segundo eixos diferentes respectivos com respeito a uma orientação espacial do primeiro sensor de campo e produzir primeiros sinais de posição indicativos dos primeiro e segundo componentes medidos. Um segundo sensor de campo magnetorresistente em um segundo pacote montável na superfície mede pelo menos um terceiro componente do campo magnético projetado em pelo menos um terceiro eixo com respeito à orientação espacial do sensor, e produzir os segundos sinais de posição indicativos do terceiro componente medido. Uma montagem de substrato orienta o primeiro sensor de campo em uma primeira orientação espacial e para orientar o segundo sensor de campo em uma segunda orientação espacial de modo que o terceiro é orientado fora de um plano contendo os primeiro e segundos eixos.
