1概述水准仪是以仪器的水平视准线作为基准线,进行高差测量的计量器具。水准仪在使用时与水准标尺配套使用。水准仪广泛用于大地水准测量、地形变测量、各种工程水准测量与大型精密机械安装调整时的测量。水准仪尽管有不同的类型,但其基本结构和工作原理是相似的。根据不同准确度和结构类型,水准仪分为水准管水准仪(图1)、自动安平水准仪(图2)和电子水准仪(图3)。
1 Overview Level is based on the instrument’s horizontal line of sight as the baseline, measurement of height measurement instruments. Level when used in conjunction with the standard ruler. Level is widely used in geodetic leveling, geodetic surveying, a variety of engineering standards and the measurement of large-scale precision machinery installation and adjustment. Although the level of different types, but its basic structure and working principle is similar. According to different types of accuracy and structure, the level gauge is divided into a level gauge (Figure 1), an automatic leveling level (Figure 2) and an electronic level (Figure 3).
