摘要： The present invention relates to a cylinder which has hollow portion therein; a piston rod which is inserted through an upper side of the cylinder and has a groove pattern having plurality of convex portions and concave portions which are alternately formed; a piston valve which is connected with a lower end of the piston rod so as to be reciprocated in the cylinder and has a fluid passing hole which is formed in an up and down direction; a rod guide which closes up an upper end of the cylinder tightly and guides an up-down movement of the piston rod and which has a through-hole at a side portion thereof; and a sensor module which is installed to the rod guide so as to detect a movement of the piston rod by using a variation in magnetic field generated when the piston rod is moved.

摘要： The present invention relates to a cylinder which has hollow portion therein; a piston rod which is inserted through an upper side of the cylinder and has a groove pattern having plurality of convex portions and concave portions which are alternately formed; a piston valve which is connected with a lower end of the piston rod so as to be reciprocated in the cylinder and has a fluid passing hole which is formed in an up and down direction; a rod guide which closes up an upper end of the cylinder tightly and guides an up-down movement of the piston rod and which has a through-hole at a side portion thereof; and a sensor module which is installed to the rod guide so as to detect a movement of the piston rod by using a variation in magnetic field generated when the piston rod is moved.According to the present invention, since the sensor can be directly installed to the damper to detect the movement of the damper, it is possible to precisely control the damping force of the damper on the basis of the detected result.
