DEVELOPMENT OF CAPACITANCE INSTRUMENTS FOR DEFORMATION AND SEEPAGE MONITORING IN DAM MONITORING SYSTEM

Now the size and the total number of dams in China occupy the first place in the world. Automatic instruments and systems with high techniques and reliability are required by new projects and by the innovation of old monitoring systems. To satisfy the urgent market demands, NARI has developed various instruments on the basis of the capacitance coordinate meter and capacitance wire alignment transducer. For example, the static leveling gauge, the capacitance seepage gage, the two dimensional or three dimensional crack meter, the high accuracy displacement meter and intelligent modular distributing data acquisition system have been applied widely to projects. This paper introduces the working principles, performance and the application of these instruments.
