摘　　要：简介了大量程谐振弦式位移传感器的工作原理和结构。在结构设计理论分析后,导出了位移和输出频率之间的理论公式,并作了修正。利用修正公式对已测得的标定数据进行处理,求出了传感器系数和引用误差。The diagram of the vibrating wire displacement probe with wide range is given schematically and its working principle is described. After the theoretical analysis for this transducer, the theoretical expression between displacement and output frequency is derived. Then the theoretical formula of this transducers is revised. Finally, the calibration data are given, the constants and the quotative error of the transducer are calculated by the revised formula.
