Abstract :Position measurement is a key technique of elect ro - hydraulic cont rol 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 experiment s , the influ2 ence 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 elect ronic circuit of measurement sensor is designed.
Keywords : Hydraulic cylinder , position measurement Hall t ransducer.
