On what principle was the spirit level invented?
The level ruler is mainly used to detect or measure the level and verticality, and can be used for inspection, measurement, marking, equipment installation, and industrial engineering construction. Many friends are not familiar with the principle of the level ruler. Below is a brief introduction for everyone.
Whether it is a traditional level or an electronic level, its principle is based on the principle of liquid level, that is, in a closed container, as the container tilts, the liquid inside will also tilt and remain horizontal.
The level ruler has a leveling bubble, which is a closed circular container filled with liquid that will not freeze, has good fluidity, can emit fluorescence, and has good stability; When the horizontal bubble is in a horizontal position, the bubble will occupy the highest position inside the tube. If the horizontal bubble tilts towards one end, the bubble will move to the highest position at the other end. Therefore, the position of the bubble inside the horizontal bubble also reflects the degree of tilt of the object being measured.
What is the working principle of electronic level ruler
An electronic level ruler is made by adding electronic circuits to a regular level ruler, usually using laser measurement and LCD display. Its basic principle is the same as that of a level ruler, and its specific working principle is:
The electronic level ruler includes a ruler body and a leveling bubble. At each end of the leveling bubble, infrared emitting tubes and infrared receiving tubes are respectively placed on both sides, which are connected to the power supply and correspond to the position. The output end of the infrared receiving tube is also connected to an electronic circuit that displays the position and status of the water bubble. When measuring, when the bubble moves to the left or right, the intensity of the infrared receiver tube at the corresponding end changes, causing the output end to produce a corresponding low level. After passing through the electronic circuit, the position of the bubble is displayed.
Compared with traditional level rulers, electronic level rulers have better accuracy and sensitivity due to the infrared receiver tube having a certain receiving range for infrared emissions and higher sensitivity to light.
