The level is a commonly used measuring tool for measuring small angles. In the machinery industry and instrumentation manufacturing, it is used to measure the inclination of the relative horizontal position, the flatness and straightness of the machine tool guide rail, the horizontal and vertical position of the equipment installation, etc. Level, can be divided into frame level and ruler level two; according to the level of the fixed way can be divided into: adjustable level and non-adjustable level.

Description of the working principle of the level

The level is a commonly used measuring tool for measuring small angles. In the machinery industry and instrumentation manufacturing, it is used to measure the inclination of the relative horizontal position, the flatness and straightness of the machine tool guide rail, the horizontal and vertical position of the equipment installation, etc. Level, can be divided into frame level and ruler level two; according to the level of the fixed way can be divided into: adjustable level and non-adjustable level.

The level is mainly used to detect the straightness of the guide rails of various machine tools and other types of equipment and the horizontal and vertical positions of equipment installation. It can also be used to measure small angles and working surfaces with V-grooves, as well as to measure the parallelism of cylindrical workpieces, as well as the horizontal and vertical positions of installation. The bubble level is a measuring instrument that checks whether the machine mounting surface or flat plate is horizontal and measures the tilt direction and angle. Its shape is made of high-grade steel. It is equipped with a long and curved glass tube, and a small horizontal glass tube is attached to the left end. The tube is filled with ether or alcohol and leaves a small bubble, always at the high point inside the tube. The bubble on the glass cylinder has a scale at both ends. Generally, when the machine is installed in the factory, the sensitivity of the commonly used bubble level is 0.01 mm/m, 0.02 mm/m, 0.04 mm/m, 0.05 mm/m, 0.1 mm/m, 0.3 mm/m and 0.4 mm/m. That is, the level is placed on a ruler or a flat plate with a length of 1m. When there is a difference in the sensitivity indication at one end, if the sensitivity is 0.01 mm/m, it means that there is 0.01mm at both ends of the straight gauge or flat plate. Height difference (equivalent to 2 seconds difference between the two ends), when 1m long has hmm height difference, the bubble will have scale difference. The principle of the bubble level is to use the bubbles in the glass tube to keep the bubbles in a high position

For a certain inclination angle, if the movement of the bubble is large (that is, the so-called sensitivity is good), the arc radius (R) needs to be increased. If the distance between each scale of the level is 2mm and the sensitivity is 0.01 mm/m, the difference between the two ends of the equivalent 1m is 2 seconds. That is, the radius of the bubble tube is 206.185 meters, and the equipment is in the frame. Different sensitivities have different radii, which are not directly related to the length of the frame.

Check before using the level, first place the level on the flat plate, read the scale of the bubble, then place the level upside down in the same position, and then read the scale size. If the reading is not correct, the relationship between the level base and the bubble tube is correct. Otherwise, use the fine-tuning screw to adjust the readings exactly the same, can be measured. If you want to check the accuracy of the level, you can use the known angle of the sine rod and the gauge block. At the same time, it can also be used with sine rod and level to measure larger inclination.

As a substitute for the traditional bubble cap inclination, the new level is more used in road engineering, mechanical measurement, construction engineering, industrial platforms, petroleum measurement, military industry, ships and other occasions where inclination or leveling needs to be measured in the gravity reference system.

According to the material classification, level can be divided into plastic level and glass level. The precision of plastic level is low, and the precision of glass level is high. High-precision level instruments with good quality in foreign markets, such as SOLA, BOSCH, ECONNS, EPOCH, RISUX. Domestic famous brands are: Oriental Precision, Great Wall, Hengrui and so on. ..

The electronic level is used to measure the surface of high-precision machine tools, such as CNC lathes, milling machines, cutting machines, and three-dimensional measuring machines. Its sensitivity is very high. The workpiece can only be measured within a certain range of inclination. The main principles of the electronic level are inductive and capacitive. According to the different measurement direction, it can also be divided into one-dimensional and two-dimensional electron level.

Induction principle: When the base of the level is tilted due to the tilt of the measured workpiece, the voltage of the induction coil changes due to the movement of the internal pendulum. Measurement principle f capacitance level is a circular pendulum suspended freely on a thin line, the pendulum is affected by gravity, suspended in a frictionless state. There are electrodes on both sides of the pendulum, and the capacitance is the same when the gap is the same. If the level is affected by the measured workpiece, the difference in capacitance will cause the angle of the two gap distances to be different.
