Abstract

CILINDRO HIDRÁULICO. Um primeiro sensor MR (28) e um segundo sensor MR (30) são uma combinação de um primeiro padrão de elemento de efeito magnetorresistivo e de um segundo padrão de elemento de efeito magnetorresistivo, e o primeiro sensor MR e o segundo sensor MR estão dispostos espaçados de uma distância prescrita de modo que, quando o primeiro sensor MR receber a maior quantidade do componente de campo magnético de um imã (26) orientado paralelamente à direção axial de um pistão (18), o segundo sensor MR recebe a maior quantidade do componente de campo magnético de um imã orientado paralelamente à direção radial do pistão.
