| Abstract: | Position measurement is a key technique of electro-hydraulic control system. Based on vortex principle and hall effect, a position measuring method that can be integrated into hydraulic cylinder was presented. In the paper the measuring principles, integrated way of sensor in hydraulic cylinder, feature and applying occasion are analyzed in detail. By means of experiments, the influence on measurement signal of hydraulic cylinder velocity, gap between sensor and piston rod and smearing layer on rod surface are studied. At the same time, the electronic circuit of measurement sensor is designed. |
