The invention relates to a single-rod hydraulic oil cylinder with a built-in sensor, and belongs to the field of hydraulic actuating mechanisms. The single-rod hydraulic oil cylinder comprises a cylinder barrel (1), a piston (2), a piston rod (3), a piston rod lug ring (7), a displacement sensor shell (8) and a movable iron core connecting rod (9). Compared with the prior art, the single-rod hydraulic oil cylinder has the following beneficial effects that the hydraulic oil cylinder is compact in structure, the displacement sensor is not in contact with the external environment, the working reliability is high, and the measurement precision is high. 本发明涉及一种内置传感器单出杆液压油缸，属于液压执行机构领域。其包括：缸筒(1)、活塞(2)、活塞杆(3)、活塞杆耳环(7)、位移传感器壳体(8)、动铁芯连杆(9)；与现有技术相比较，本发明具备如下有益效果：液压油缸结构紧凑，位移传感器不与外界环境接触，工作可靠性高，测量精度高。
