The level tube of the level gauge is made of glass. The inner wall of the level pipe is a curved surface with a certain radius of curvature. The liquid is filled in the pipe. When the level meter inclines, the bubble in the level pipe moves to the rising end of the level gauge, so as to determine the position of the horizontal plane. The larger the curvature radius of the inner wall of the leveling pipe, the higher the resolution is. The smaller the curvature radius is, the lower the resolution is. Therefore, the curvature radius of the leveling pipe determines the accuracy of the leveling instrument. The leveler is mainly used to check the flatness, straightness, perpendicularity of various machine tools and workpieces and the horizontal position of equipment installation. Especially in the measurement of perpendicularity, the magnetic level can be absorbed on the vertical working face without manual support, which reduces the labor intensity and avoids the measurement error brought by human body heat radiation.
The bottom and side length of the level is 2000mm, and the accuracy is generally (0.02-0.025) mm / m. if the user has special requirements, it can be customized separately. Compared with the conventional structure, the zero adjustment structure of the level instrument has its own unique features: 1. 2. After adjustment, the zero position is not easy to change. As shown in Figure 1. When the V-groove surface of the bottom of the level instrument rotates 5 around the mandrel, if the bubble moves, the requirements can be met by adjusting the screw 2. This item has been adjusted before delivery and generally remains unchanged.
The structure of the level is different according to the classification. The frame level is generally composed of the main body, horizontal level, insulated handle, main level, cover plate and zero adjustment device. The ruler level is generally composed of the main body, cover plate, main level and zero adjustment device.
Level gauge is a kind of measuring tool which takes level as measuring and reading element. The level is a sealed glass tube, and the profile of the inner surface is an arc surface with a certain radius of curvature. The glass tube of the level contains liquid with smaller viscosity coefficient, such as alcohol, ether and their mixture. The part without liquid is usually called level bubble. There is a certain relationship between the curvature radius of the inner surface profile of the glass tube and the graduation value.
