水平仪是常用的测量小角度一种普通量具,在机械与仪器仪表制造业中,用它来测量相对于水平位置的倾斜角度,测量两部件的相互平行性和垂直性;用它来测量机床、仪器导轨的平直度,平板的平面度等等。水平仪的构造原理,分为两种。一种是水平原理,如气泡式水平仪;另一种是铅直原理,如电子水平仪(也有水平原理的)。气泡式水平仪,按其结构形式不同又分为框式和钳工水平仪、合像水平仪。水平仪的分度值,通常以弧度单位表示,
Level is commonly used to measure the small angle of a general gauge, in the mechanical and instrumentation manufacturing, used to measure the tilt angle relative to the horizontal position, measuring the mutual parallelism and verticality of the two components; use it to measure the machine tool, Instrument rail straightness, flatness and so on. Level structure principle, divided into two kinds. One is the principle of level, such as bubble level; the other is the principle of vertical, such as the electronic level (also the principle of level). Bubble level, according to their different forms of structure is divided into box-type and fitter level, like a level instrument. Grading instrument level, usually expressed in radians,
