摘　　要：油缸行程的测量是整个液压同步提升控制的关键.由于以往机械式测量方法的诸多缺点,所以提出了基于磁栅传感器的油缸行程测量系统设计,以提高油缸行程测量值的精度和准确性.The measurement for the cylinder's displacement is the key to the whole control of hydromatic lift- ing in phase.Because of the disadvantages of the mechanic measurement the design of the measurement for the cylinder's displacement system based on the magnetic grid sensor is provided in order to improve the accuracy and precision of the measurement for the cylinder's displacement.

关 键 词：磁栅 磁头 位移传感器
