Magnetic Field Mapper
DX-2012R series Magnetic Field Mapper is a 3D magnetic field mapping system that can provide test reports such as XY coordinates, P polar coordinates, 3D magnetic field distribution and relative fundamental wave harmonic analysis, etc., to meet the quality inspection of permanent magnets, permanent magnet motor stators or rotors, DC magnetic field coils, and electromagnets.
DX-2012R series surface magnetic field distribution measuring instrument independently developed by Dexinmag company is an indispensable tool for the correct evaluation of magnet magnetization accuracy and quality inspection of magnetic rings.
This 3 axis magnetic field mapping equipment can be equipped with a variety of test fixtures (such as three-dimensional test probes, rotating platforms or loading platforms). With a high concentricity design and high precision level of probe return.
The scanning space of the product is 800mm*800mm*800mm.

The space magnetic field distribution measuring instrument is mainly composed of an industrial computer (measurement software), motion control system and data acquisition system.
First, the test command is sent through the industrial control computer to control the motion control system to complete the set motion trajectory, and simultaneously control the work of the data acquisition system. The data acquisition system collects data in the X, Y, and Z directions through the Hall sensor, and then transmits the data to the industrial control system. The computer performs data processing and finally obtains a three-dimensional magnetic field distribution map.
