Capacitive high wave sensors sampling stability experiment

CHEN Jin;CHEN Guang-lai;CHEN Han-bao;Tianjin Key Laboratory of the Design and Intelligent Control of the Advanced Mechatronical System,School of Mechanical Engineering,Tianjin University of Technology;Tianjin Research Institute for Water Transport,M.O.T;  
Wave height sensor is one of the most important testing instrument for hydraulic test,therefore the high accuracy and stability is necessary,however,in the actual process of using,the sampling results will appear relatively large amplitude fluctuation,and the frequency is high,this phenomenon lead to inaccurate measurement of wave height data,and then influence the actual hydraulic experiment results hardly,in this article,the author try to find the sampling results fluctuating rule through the experiment,and use mathematics method to eliminate these fluctuations,then increase the stability of the sampling.
