Fully automatic multi-dimensional magnetic field measurement system for high-precision AC and DC 3D magnetic field mapping and analysis.
Product Overview
The DX-2012F Multi-dimensional Magnetic Field Testing System is a high-precision fully automatic digital magnetic measurement platform developed by Dexinmag.
The system can test the three-dimensional magnetic field distribution of AC and DC magnetic fields in any spatial configuration with very high precision. It can measure and analyse:
- 3D magnetic field distribution
- Surface magnetic structures of various shapes
- Uniform magnetic field distribution
- Multi-pole magnetic rings
- N/S magnetic pole distribution
- Motor magnetic field distribution
- Superconducting magnetic field
- Magnetic resonance imaging (MRI) magnetic field
Measurement results can be converted into graphical visualisations, stored as digital data and exported for reporting and printing.
This system is widely used for magnetic research and testing of AC and DC magnetic fields and has been adopted by many aerospace, military and scientific research institutions worldwide.

System Configuration
The system includes:
- Industrial PC with control software
- High-precision Gauss meter (1D or 3D)
- Hall probe compatible with the Gauss meter
- Multi-axis displacement control unit
- Displacement platform controller
The system consists of two main parts:
Data Acquisition System
