Let's discuss the characteristics and advantages of the DC measurement device for FE-2100SD soft magnetic materials.
metal soft magneticMeasurement of DC magnetic properties of materialsIt has always been one of the focuses of the development of the industry, and this technology has also made breakthrough progress. Let's discuss it together.DC Measuring Device for FE-2100SD Soft Magnetic MaterialsFeatures and advantages.
magnetic materialThe measurement needs to be carried out around different aspects of magnetic laws, which include basic macroscopic magnetic laws and magnetic units, material magnetic laws, strong magnetic material magnetization laws, sample magnetization laws and material.magnetic effect.
In 2021, the IEEE MAGNETICS LETTERS magazine included the publicationAutonomous University of Barcelonaprofessor chan tuk-hang led the team,Hunan Yongyi Technology Co., Ltd.Complete About Metalssoft magnetic materialBreakthrough in DC magnetic performance measurement.
Through the use of high-resolution DC program-controlled power supply and low drift integrator, as well as the impact method of automatic control, the accurate measurement of the DC magnetic properties of Permalloy closed-circuit samples was successfully realized, and on the basis of the establishment of the eddy current model, the quantitative analysis of the scanning method and the impact method was carried out, which provided a new idea for the further improvement of the DC magnetic properties of soft magnetic materials!
DC Measuring Device for FE-2100SD Soft Magnetic MaterialsIs a comprehensiveAutomatic measuring instrument for DC magnetic properties of soft magnetic materials.
DC Measuring Device for FE-2100SD Soft Magnetic MaterialsIt is mainly used to measure the basic magnetization curve and hysteresis loop of various soft ferrite, pure iron, silicon steel, permalloy, amorphous and nanocrystalline ring-like or open-circuit strip soft magnetic materials under DC static state, and accurately measure the static magnetic characteristic parameters such as initial permeability μi, maximum permeability μm, saturation magnetic induction strength Bs, remanence Br and coercivity Hc.
On the basis of completing the scanning method & simulated impact method,DC Measuring Device for FE-2100SD Soft Magnetic MaterialsRight.Impact waveform, signalImproved upgrades, while optimizing integrator drift control technology, are at the forefront of the industry in testing micro-components, low Hcj, low Br materials, and core materials.

JJF 1830-2020 Calibration Specification for DC Magnetic Properties Measuring Instruments for Soft Magnetic Materials, in which the primary current,magnetic fluxThe calibration specifications for testing the uniformity of the coil constant and the magnetic conductivity meter are basic, which are also simple and direct for magnetic measurement workers, and are also basic requirements for product manufacturers.
However, the calibration specifications for the magnetic characteristic parameters involved include the calibration of ui, um, Bs, Br and Hc parameters. The specifications refer to electrical pure iron and permalloy rings.Standard sampleBecause the standard sample is the determination of the detection level of the test equipment, the calibration specification can be successfully implemented, and a case needs to be inserted here to explain.
In ASTM A596/A773M-14 standard for loop meter measurement, the measured value quality is based on a comparison report of measured values of 3 samples written by 10 laboratories (equipment supplied by 5 equipment) in 2007, which is usedMeasurement accuracyAnd for the British National Physical Laboratory (NPL) measured values to illustrate the deviation.
1J85, pure iron and ferritic stainless steel were used in the experiment, and its maxrelative permeabilityFor 370k, 10.9k and 1.23k, the magnetic field Hs of the measuring loop is 4, 400 and 1200 A/m respectively. Compared with the results, the worst case occurs in the Hc of 1J85, which has a typical repeatability of 1.4 in the laboratory and 52% in the laboratory, so the test accuracy is extremely low. The test average deviates from NPL's Hc = 0.562 A/m by 34.7! It is said that NPL's measurement system is composed of components that can be calibrated separately and can be replaced as needed, but it is not specified what method is used to ensure the correct measurement, which should be a classic impact galvanometer.
Hunan Yongyi Technology Co., Ltd.Through 6 years of research on DC magnetic measurement of soft magnetic materials, two inventions have been obtained in closed-circuit sample measurement, which can be used for scanning method experiment and automatic measurement of impact method. The experimental results of our test 1J85 are provided below.

It was found that the difference in the asymmetry of the coercivity Hc measured by the impact method was 2.2;
2. The test data Br and Hc of the scanning method are always greater than those of the impact method (although the control scanning speed is already very slow, there is always the influence of metal eddy current damping).
The current solenoid selection is as follows: LXG5580,LXG8024,LXG3280 and LXG18024 (the product name is based on LXG solenoid length cm magnetic field strength kA/m). Users can design according to actual sample measurement requirements.
It is mainly used to measure the basic magnetization curves and hysteresis loops of various soft ferrite, pure iron, silicon steel, permalloy, amorphous and nanocrystalline and other ring-like or open-circuit strip soft magnetic materials under DC static.
