摘要
介绍了采用ＣＣＤ作为传感器，研制用于大坝监测的引张线观测仪和倒垂线观测仪的设计方法。仪器测量范围为几厘米，精度优于０．１ｍｍ，具有结构简单，数字化，自动测量及远距离数据传输等优点。
It is described in detail that the instruments of tention wire and inverse plumb line for the monitor of dams are developed by using the CCD as the sensor. The measuring range of the instruments is several centimetres, and the accuracy is less than 0.1 millimetre. Simple constitution, digitalisation, automatic and remote data transmission are their advanced features.
