In order to satisfy foreign users to investigate the testing capability of Yongyi Science and Technology FE-2100RMD's multi-pole magnetic ring, a more detailed testing experiment was carried out, and the data were analyzed and summarized, basically achieving the ideal effect. Through the experimental summary, the product can be used as a test standard for reference in the later period, so as to ensure the accuracy and consistency of product testing while mastering its own product testing capability.
To meet the needs of foreign usersEternal TechnologyFE-2100RMDmultipole magnetic ringTest ability inspection, more detailed test experiments, and data analysis and summary, basically achieve the desired effect, through the experimental summary, later on the product can be used as a reference for inspection standards, in the mastery of their own product testing ability at the same time, to ensure product testing accuracy and consistency.
1. Select magnetic ring octopole samples and randomly mark four approximate test positions for taking and placing samples for testing and examination;
2. Refer to the circlip carried by the sample and use it as the stop height installed on the chuck;
3. Load the chuck and use the circlip as a reference to ensure that the probe return test point is on a horizontal plane.
4. Adjust the probe to the middle of the ring, set the test point position and the stop point position, and start the test (the chip is 0.3mm from the magnetic ring wall).
5. Randomly control the height according to the requirements of continuous installation test 4 times, corresponding to the distribution of each magnetic pole corresponding to the situation
The repeatability of the fixed position corresponding to the 5-1 4 times superposition assessment equipment is as follows:
5-2 Peak Max Absolute Deviation:2Gs, absolute deviation of minimum magnetic field value: 0Gs; Maximum deviation of average value: 1Gs;
5-3 Absolute deviation of maximum pole width of magnetic pole:0.02 °, absolute deviation of minimum pole width of magnetic pole: 0.03 °;
5-4 The corresponding table of the four magnetic pole widths is as follows (unit: °):
