Advantages of full angle Leeb hardness tester

advantages of full angle Leeb hardness tester:

1. Full angle Leeb hardness tester is for single angle Leeb hardness tester. At present, almost all Leeb hardness testers on the market are single angle Leeb hardness testers. The calculation principle is based on the vertical downward direction of the impact device (probe). Therefore, when changing the angle measurement, the calculated Richter value, with the continuous rise of the angle, also shows a continuous increase. At the same time, for materials with different hardness, the increase range is also very different. For example, when testing a hld750 test block, it is hld750 when measured vertically downward. When changing the angle to horizontal test, the Richter value is hld757, which is 7 Richter values higher than the actual value. Similarly, for the test block of hld530, the Richter scale value during the horizontal test is hld542, which is 12 times higher than the actual value. It can be seen from this example that for the same material, after changing the angle measurement, the measured Richter value is different. For materials with different hardness, the change degree of Leeb value is also different by changing the same angle measurement. This is the so-called single angle Leeb hardness tester, that is, only the Leeb hardness calculated when it is vertically downward is true, and the Leeb hardness values in other directions are obviously not true. It will cause great measurement error in practical application

2. In order to solve the problem of measurement error, it is often through artificial compensation to eliminate the large deviation caused by angle transformation in measurement, so that it can meet the accuracy requirements as much as possible. However, this kind of artificial compensation is only to reduce the error to a certain extent, which is a last resort. The experimental principles of experimental machines with different experimental functions are different. It is a processing means, not a fundamental solution. There is an option to set the direction on the Leeb hardness tester, which is actually an artificial compensation program specially designed to compensate for the direction error. When it is necessary to measure in which direction, select which direction on the instrument, so that the calculated hardness value can meet the error requirements after the compensation program designed in advance by the instrument. This artificial compensation is very rough in accuracy. It is compensated every 45 degrees. For materials with different hardness, it is compensated every 50 Leeb hardness values. Obviously, this compensation is neither continuous nor linear. If your measurement direction is just 22.5 degrees, it becomes a problem which angle you should choose to compensate. At the same time, the hardness of your material is just in the middle of every 50 Richter value compensation, plus the systematic error of the instrument, the accuracy of the measurement results can be imagined

3. Recently, foreign countries are also striving to continuously improve the performance of products, so that the instrument can automatically identify the measurement angle, and further reduce the compensated gradient after simple mathematical processing, reducing the error range. But basically, we still change the soup without changing the medicine, but to different degrees. The birth of full angle Leeb hardness tester completely solves this problem. To be exact, this problem does not exist in full angle Leeb hardness tester, and it does not matter "solution". Valves, imported pumps, industrial washing machines

4. Full angle Richter hard in 2016, the measurement of 109 durometers from China's power battery manufacturers in any angle is to meet the requirements of changing hydraulic oil; The hardness value is calculated based on the Rockwell principle. It doesn't matter whether it is upward, downward or horizontal. The same measurement results are obtained for the same workpiece in different directions, which greatly improves the measurement accuracy. Full angle can be said to be the winner in the automotive field today. The accuracy of the baby durometer is generally much higher than that of the single angle durometer, especially in the measurement of different directions. Generally, the accuracy of the full angle hardness tester should be ≤± 0.3% (when hl=800), and the repetition accuracy should be about ± 2HL

4. The full angle Leeb hardness tester is a revolutionary product based on new theories and calculation methods, marking that the development of Leeb hardness tester in China has reached the international leading level
