振弦式位移计校准方法的研究

振弦式位移计在水运工程等领域广泛应用,但是国内一直未发布与其专门相关的检定规程或校准规范,缺乏完整的振弦式位移计溯源方法。该文介绍了振弦式位移计的工作原理,提出了振弦式位移计的具体校准方法,选取样机进行了试验测量,论证了校准方法的可行性,为振弦式位移计的质量控制提供了保障。

Study on calibration method of vibrating string displacement meter

Vibrating string displacement meter is widely used in the field of water transport engineeringand other fields,but there are no verification regulations or calibration specifications published in China,and there is no complete traceability method for vibrating string displacement meter.The working principle of vibrating wire displacement meter is introduced,and the specific calibration method of vibrating wire displacement meter is put forward.The prototype is tested and the feasibility of the calibration method is demonstrated,which provides a guarantee for the quality control of vibrating wire displacement meter.
