What is the working principle of an electronic level
1, What principle was the level invented based on
A level 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 a level. Below, we will briefly introduce it to you.
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 horizontal.
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. Therefore, the position of the bubble inside the horizontal bubble also reflects the degree of inclination of the measured object.
2, What is the working principle of an electronic level
An electronic level is made by adding electronic circuits to a regular level, usually using laser measurement and LCD screen 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. On both sides of each end of the level bubble, there are infrared emission tubes and infrared receiver tubes connected to the power supply and corresponding to the position. The output end of the infrared receiver 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, it causes a change in the light intensity of the corresponding infrared receiving tube, resulting in a corresponding low level at its output end. After passing through an electronic circuit, the position of the bubble is displayed.
Compared with traditional level, electronic level has better accuracy and sensitivity due to the infrared receiving tube having a certain receiving range for infrared emission and higher sensitivity to light.
