What is the function of a level ruler? What types of level rulers are there?
A spirit level, as the name suggests, is a ruler used to measure horizontal position. It is a measuring tool that uses level bubbles to indicate values and directly displays angular displacement through the level bubbles of the liquid inside the spirit level, thereby measuring information such as the relative horizontal position, vertical position, and deviation of the measured surface from the inclined position. The practical applications of a level ruler mainly include:
1. Detect and adjust the horizontal position of mechanical equipment such as machine tools, instrument guides, and instrument bases.
2. Measure the inclination angle relative to the horizontal plane, such as the straightness and flatness of machine tools, instrument guides, rulers, and flat plates.
3. Measure the perpendicularity and parallelism of the mutual position between two planes to assist in building installation.
What are the types of level rulers
There are many types of level rulers, which can also be classified into different types according to different classification standards:
1. Divided by principle
(1) Mechanical level ruler: including bar level ruler (a rectangular level measuring instrument with a base measuring surface and a level bubble fixed or adjustable relative to the base measuring surface), frame level ruler (a frame level measuring instrument with a base measuring surface and two vertical measuring surfaces, and a level bubble fixed or adjustable relative to the base measuring surface), and magnetic level ruler (a base measuring surface and a side surface with magnetic attachment, which can be used for suction measurement of the Z-axis of machine tools and instruments, with magnetic switches)
(2) Electronic level ruler: an electronic level ruler that uses a display light instead of a water bubble, and visually determines whether it is level by observing the color of the display light; There are also more intuitive digital level rulers that can directly display numbers, but they are not very durable and are therefore relatively rare.
2. Divided by structure
It is mainly divided into two types: adjustable level ruler and non adjustable level ruler.
