Magnetic Testing
Magnetic Shielding Device
Magnetic shielding devices engineered to reduce or eliminate unwanted magnetic fields in sensitive environments, ensuring accurate and stable operation of precision instruments and measurement systems.
Product Overview
Magnetic shielding devices are designed to attenuate external magnetic fields and prevent interference with sensitive equipment. By using high-permeability materials and optimised shielding geometries, these devices create a controlled low-field region where precise measurements and stable operation are possible.
MAGTRANS magnetic shielding solutions can be tailored for DC and low-frequency magnetic fields and integrated into existing or new installations. Typical applications include magnetic measurement laboratories, precision electronics, medical imaging equipment, metrology facilities and research environments where background magnetic noise must be minimised.
Shielding configurations can be provided as standalone enclosures, modular panels or customised assemblies around specific instruments, enabling flexible deployment while maintaining high field attenuation performance.
Magnetic Shielding Device
The magnetic shielding device is mainly used to shield environmental magnetic fields, especially the earth's magnetic field. The inside of the shielding tube can form a near-zero magnetic space where the magnetic induction intensity in air can be less than 1 nT.
To meet user requirements for near-zero magnetic environments, the shielding tube offers a compact structure, lightweight design and easy operation while maintaining high cost-performance.
The magnetic shielding cylinder is made from multiple layers of high-permeability materials, typically permalloy, which effectively shields magnetic field interference from environmental sources.
These shielding devices are widely used in:
- Magnetic sensor research and development
- Magnetometer calibration
- Magnetic material research
- Weak magnetic field experiments
