The invention discloses a built-in magnet ring detecting device for a hydraulic cylinder. The built-in magnet ring detecting device comprises a displacement sensor, a sensor power supply. The sensor power supply is electrically connected with the displacement sensor. The displacement sensor comprises a magnet ring state indication element, a measuring electronic head and a sensing rod. The magnet ring state indication element and the sensing rod are connected with the measuring electronic head. When the sensing rod is positioned in a hydraulic cylinder without a built-in magnetic ring, an indication is given by the magnet ring state indication element, and we the sensing rod is positioned in a hydraulic cylinder with the built-in magnet ring, no indication is given by the magnet ring state indication element. The built-in magnet ring detecting device for the hydraulic cylinder has the advantage that replacement and maintenance efficiency of the hydraulic cylinder is increased. 本发明公开了种液压缸内置磁环检测装置，包括：位移传感器，传感器供
