Introduction
The DXGE-30S geomagnetic dynamic simulation shielding system can stably and efficiently generate the equivalent high-precision magnetic field in the opposite direction of the geomagnetic field. Using the cutting-edge high-precision fluxgate meter, real-time feedback and real-time adjustment are realized.
The core function of DXGE-30S system is to cancel the geomagnetic field fluctuation in real time. Through this function, it is able to create a zero magnetic environment with a precision of up to 10nT in the geomagnetic environment. This means that even in the environment of strong geomagnetic interference, it can provide a near interference-free experiment site for scientific researchers.
The DXGE-30S system also offers excellent flexibility. In the shielding chamber or shielding cylinder, it can generate 1nT or 0.1nT gradient magnetic fields, and even generate any magnetic field Settings according to experimental requirements. In addition, the system has been praised for its excellent performance and wide range of applications. Whether it is in the aerospace field, or in military and scientific research institutions such as universities, it plays an indispensable role. Its high precision, stability and digital degree have reached the industry-leading level, and have been praised by the majority of users.
System composition
Magnetic flux generating device
1. Three-dimensional coil structure: The core of the flux generating device is a set of three-dimensional coils specifically designed to generate the uniform magnetic field required for the experiment. Each dimension has a set of coils that ensure an even distribution of the magnetic field in all three directions.
2. Power control system: Three corresponding power supplies are matched with the three-dimensional coil, and each power supply is responsible for controlling a dimension of the coil.
3. High-precision fluxgate probe: In the center of the device, a high-precision inlet fluxgate probe is placed. This probe acts as a feedback test tool for magnetic field regulation and can sense changes in the magnetic field in real time.
4. Upper computer feedback adjustment: the upper computer receives feedback signals from the fluxgate probe, and adjusts the output current value of the high-precision power supply through calculation and analysis. This feedback adjustment mechanism ensures precise shielding of the geomagnetic field, enabling the generation of the precise magnetic field required for the experiment.
magnetic field measuring device
1. DX-330F fluxgate meter: As the core component of the magnetic field measurement device, DX-330F fluxgate meter has high precision and stability.
2. Fluxgate probe: Used in conjunction with the DX-330F fluxgate meter is a fluxgate probe, which is located in the center of the coil and is responsible for sensing the magnetic field strength in a uniform magnetic field in real time.
3. Real-time feedback mechanism: The fluxgate probe will feedback the measured magnetic field data to the DX-330F fluxgate meter in real time, and then provide accurate reference data for the adjustment of the flux generating device to ensure the magnetic field accuracy and stability of the experimental environment.
