摘　　要：中国的坝工建设从筑坝规模到数量均居世界首位。新建工程的监测系统建设和老坝的监测系统更新改造都需要技术先进、质量可靠的自动化监测仪器和系统。本文介绍了电容感应式静力水准仪、量水堰渗漏量仪、双向、三向测缝计、高精度位移计及智能模块化的分布式数据采集系统等新型监测仪器和系统的研制及工程运用实例。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.
