currentmagnetic fieldanalog

DXGE-30S geomagnetic dynamic analog shielding system can stably and effectively generate an equivalent high-precision magnetic field opposite to the direction of the geomagnetic field, and use a high-precision fluxgate meter for real-time feedback and real-time adjustment. The DXGE-30S system can offset the magnetic field fluctuations of the geomagnetic field in real time, thereby generating a 10nT zero magnetic environment in a geomagnetic environment. For example, a 1nT or 0.1nT gradient magnetic field can be generated in a shielding room or a shielding cylinder. Generate an arbitrarily set magnetic field for scientific experiments and simulate geomagnetic change environments. The DXGE-30S system is widely used by aerospace and military industries and colleges and universities, and its accuracy, stability and digitization degree are widely acclaimed. System composition The magnetic flux generating device consists of a set of three-dimensional coils and three corresponding power supplies. A set of three-dimensional coils is used to generate the uniform magnetic field required for the experiment. The three-dimensional coils are equipped with three power supplies to control the three-dimensional coils respectively. Each dimension has a set of coils to generate a uniform magnetic field. A high-precision imported fluxgate probe is placed in the center as a feedback test for magnetic field adjustment. The feedback signal is calculated by the host computer to adjust the output current value of the high-precision power supply, so as to achieve precise shielding of the geomagnetism and generate the required magnetic field.
