Multipolar Magnetic Field Distribution Tester

DX-2012R series multi-pole magnetic field distribution tester is a device that can provide XY coordinate, P polar coordinate magnetic field distribution data, and can detect three-dimensional magnetic field distribution, so as to comprehensively evaluate the magnetic field state. Not only that, the tester also has fundamental harmonic analysis and other functions, to provide users with a detailed and comprehensive detection report. Such characteristics make it play a vital role in the quality detection of various magnetic materials or equipment such as permanent magnet, permanent magnet motor stator or rotor, DC field coil, electromagnet and so on.

DX-2012R series surface magnetic field distribution measuring instrument is based on Dexinmag company's deep research and development strength and technology accumulation, combined with high-precision sensor, intelligent control system and humanized operation interface, can quickly and accurately measure the magnetic field strength and direction of each area in the multi-pole magnetic field. It provides strong technical support for scientific research, industrial production and medical diagnosis.

This three-axis magnetic field mapping device is designed with the actual test needs in mind and can be equipped with a variety of test fixtures, such as three-dimensional test probes, rotating platforms or loading platforms, to adapt to different test objects and scenarios. Its high concentricity design ensures the accuracy and reliability of the test data, and the probe return accuracy is high, making the test results more accurate. In addition, the scanning space of the product reaches 800mm800mm800mm, which can meet most test requirements, whether it is a large magnet or a small magnetic component, it can easily measure the magnetic field distribution.

DX-2012R multi-pole magnetic field distribution tester working principle

The multipole magnetic field distribution tester uses an advanced Hall effect sensor or magnetoresistive sensor combined with a high-speed data acquisition system and accurate algorithms to measure the magnetic field strength and direction in real time. The sensor array covers a wide range of measurement areas and eliminates environmental interference and error through sophisticated calibration and compensation technology.
