The utility model relates to a plunger cylinder, in order to overcome the defect that a hydraulic oil cylinder is installed outside an existing displacement sensor, the plunger cylinder comprises a cylinder barrel and a piston rod, the outer end of the piston rod is located outside the cylinder barrel, and the inner end of the piston rod is located in the cylinder barrel. An induction rod of the magnetostrictive displacement sensor is installed at the first end of the cylinder barrel, a magnetic part of the magnetostrictive displacement sensor is fixedly installed at the inner end of the piston rod, and a hole used for containing a measuring rod of the induction rod is formed in the end face of the inner end of the piston rod. According to the plunger cylinder, the displacement sensor is located in the plunger cylinder to be well protected, and in addition, the plunger cylinder is simple in structure and low in manufacturing cost. 本实用新型涉及柱塞缸，为解决现有位移传感器外置式安装液压油缸的缺点，本实用新型构造一种柱塞缸，包括缸筒和活塞杆，所述活塞杆的外端位于缸筒外部，内端位于缸筒中，
