Abstract

resumo patente de invenção: "método para a medição sem contato de uma posição relativa por meio de um sensor de hall". a presente invenção refere-se a um método para a medição sem contato de uma posição relativa de uma fonte de campo magnético (102) que produz um campo magnético e um sensor de campo magnético (100) um em relação ao outro. a presente invenção também se refere ainda a um sensor de deslocamento correspondente. de acordo com a presente invenção, o sensor de campo magnético (100) detecta pelo menos dois componentes espaciais (bz, by) do campo magnético e um sinal da posição é produzido a partir dos componentes medidos. o método compreende as seguintes etapas: o cálculo do sinal da posição com base em um quociente dos dois componentes do campo magnético; a correção, antes que o quociente seja calculado, do componente do campo magnético que se estende em uma direção do movimento entre a fonte de campo magnético (102) e o sensor de campo magnético (100).
