The invention discloses an oil cylinder displacement sensor which comprises a Hall sensor circuit board, a base, a first pulley, a second pulley, a magnet ring, a rotating shaft and a small magnet. The rotating shaft is rotatably arranged on the base. The first pulley, the second pulley and the magnet ring are arranged on the rotating shaft in a sleeving mode. The first pulley and the second pulley are located on the two sides of the magnet ring respectively, and abut against the magnet ring. The Hall sensor circuit board is arranged on the outer side of at least one end of the base. The smallmagnet is mounted at the end, adjacent to the Hall sensor circuit board, of the rotating shaft. The Hall sensor circuit board and the small magnet are arranged in a spaced mode. A Hall sensor is arranged on the Hall sensor circuit board, the Hall sensor is used for reading the changed magnetic induction angle of the small magnet and outputting an induction electric signal, and therefore, the linear displacement of a piston rod and a hydraulic oil cylinder barrel is detected. The oil cylinder displacement sensor has the advantages of being high in detection precision and small in size. The invention further discloses a hydraulic oil cylinder, a supporting leg leveling device, an engineering machine and a hydraulic robot.
