Coercivity Measurement System

DX-2000HC Soft magnetic coercivity measuring system is an advanced automatic magnetic testing equipment specially designed for measuring soft magnetic materials (including rod, strip, L shape, U shape, etc.) coercivity Hc static magnetic characteristic parameters.

In terms of software, DX-2000HC uses Windows-based measurement software with a user-friendly and intuitive interface and an easy-to-understand operation process, so even non-professional users can easily get started. The software allows users to easily set the measurement parameters, monitor the measurement process in real time, and quickly obtain and analyze the measurement results.

In order to ensure the accuracy and reliability of the measurement results, DX-2000HC strictly follows the relevant domestic and foreign standards, including the Chinese national standard GB3657-83, the industry standard SJ/T13888-2009 and the international standard IEC60404-7. These standards not only provide strict technical requirements for the system, but also ensure the international universality and recognition of the measurement results.

In terms of measuring principle, DX-2000HC adopts an advanced analog shock method, combines computer control technology with A/D and D/A technology, and replaces traditional shock galvanometer with an electronic integrator. This innovative measurement method eliminates the non-transient error in the classical impact method and greatly improves the measurement accuracy and speed while ensuring good repeatability. In addition, since a computer completely controls the measurement process, the influence of various human factors on the measurement results can be eliminated, which provides a reliable basis for studying the mechanism of the material magnetization process.

Wide range of test sample types: The DX-2000HC system supports a wide range of soft magnetic materials, including but not limited to soft magnetic ferrites, permalloy, amorphous, nanocrystals, iron powder cores, electropure iron, and silicon steel sheets. This broad compatibility enables the system to meet the needs of different scientific and industrial applications.

Diverse sample shapes: The system supports open-circuit sample measurements in a variety of shapes, such as rod, sheet, L-shape, U-shape, etc. This flexibility allows users to select the right sample shape for testing according to specific application scenarios and experimental requirements.

Direct measurement system: The system can directly measure the sample with open solenoid and measuring equipment. The sample, magnetization coil (N1), and measurement coil (N2) together form a complete measurement system to ensure the accuracy and reliability of the measurement.

High-precision magnetic field locking: The system indirectly measures the magnetic field strength by measuring the magnetization current, and its magnetic field locking accuracy is up to 0.1%. This high precision ensures the accuracy and repeatability of the measurement results.

Advanced electronic integrator technology: Unlike the manual zeroing and stabilization methods commonly found on the market, the DX-2000HC system uses advanced electronic integrator technology.

The electronic integrator's zero clearing and stability adjustment are completed automatically by software without manual participation, which greatly improves the test's efficiency and accuracy.

The role of solenoids in open-circuit sample testing: When measuring open-circuit samples, solenoids, as an important component, play a key role in ensuring the stability and accuracy of the measurement system by precisely controlling the current in the solenoid; a stable magnetic field can be generated, enabling accurate measurement of the sample.

Simulation impact method test method: The system adopts the simulation impact method as the test method and measures the magnetic characteristic parameters of the sample by simulating the real impact process. This method can accurately measure the coercive force Hc value of the magnetic characteristic parameter, which provides a reliable basis for the study of the magnetization process mechanism of materials.

Automatic zero function: Before each test, the measurement system will automatically zero operation to ensure the accuracy of the measurement results. This function reduces the impact of human error and improves the reliability of the test.

Powerful and easy-to-use software: The DX-2000HC system has powerful measurement software that allows users to easily set measurement parameters, monitor the measurement process in real time, and quickly obtain and analyze measurement results. The software has very low technical requirements for testers, and even non-professionals can easily use it.

Question 1:

How do I ensure that the magnetization state of the sample is stable during the measurement process?

Answer:

Before measurement: Ensure the sample has been fully magnetized to achieve a stable magnetization state.

During the measurement process: Avoid external influences on the sample that may change its magnetization state, such as mechanical vibration, temperature changes, or strong magnetic field interference.

If desired, you can use the system's magnetization function to remagnetize the sample to ensure that it maintains a stable magnetization state during the measurement process.

Question 2:

How to interpret the measurement results of the Soft Magnetic Coercivity Measurement System?

Answer:

The measurement results of the Soft Magnetic Coercivity Measurement System are usually presented in the form of numerical values of coercivity (Hc). Coercive force is the minimum magnetic field strength required to flip the magnetized state of a material under the action of an external magnetic field. A higher coercivity value means that the material can resist external magnetic fields changing its magnetization state. When interpreting the measurement results, it is necessary to conduct an analysis based on the specific material and application background to understand whether the material's magnetic properties meet the requirements and how to optimize and improve them further.

Question 3:

Does the system require a special setup or calibration for different soft magnetic materials?

Answer:

unnecessary. The system's measurement range covers various soft magnetic materials and can be adapted to different measurement needs through simple parameter settings. However, we may provide customized solutions according to user needs for some special soft magnetic materials, such as materials with special magnetic properties or special shapes.
