What principle was the level ruler invented based on
The horizontal 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 horizontal 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. In a closed container, as the container tilts, the liquid inside will also tilt and remain level.
The level ruler has a level bubble, which is a closed circular container containing a 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, so the position of the bubble inside the horizontal bubble also reflects the degree of inclination of the measured object.
What is the working principle of an electronic level gauge
The electronic level is made by adding an electronic circuit to a regular level, usually using laser measurement and LCD display. Its basic principle is the same as that of a level, and the specific working principle is:
The electronic level includes a ruler body and a level bubble, with infrared emission tubes and infrared receivers connected to the power supply and corresponding to the position on both sides of each end of the level bubble
The output end of the infrared receiving tube is 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 light intensity of the corresponding infrared receiving tube changes, causing the output end to generate a corresponding low level. After passing through the electronic circuit, the position of the bubble is displayed.
Compared to traditional level gauges, electronic level gauges have a certain receiving range and higher sensitivity to infrared emission compared to infrared receiving tubes, resulting in better accuracy and sensitivity.
