Confirmation of the environment. We offer magnetic field measurement and testing contract services for the planned construction site, as well as effective shielding construction methods tailored to the actual conditions of the site and the customer.
We measure the electromagnetic environment of buildings such as companies, factories, and hospitals, where there are concerns about equipment malfunction or health hazards to humans due to electromagnetic wave interference. We also offer measurements of the shielding effects at installation sites for MRI and CT machines, as well as surrounding electromagnetic environments.
1) Magnetic Field Measurement
When it is necessary to know the magnetic field environment in advance, such as for the installation of devices that are sensitive to magnetic fields, please make use of our environmental measurement services.
2) Examples of On-Site Measurements
- Installation sites for electron microscopes
- Installation sites for semiconductor manufacturing equipment
- Locations of hospital facilities and testing equipment
- Near power transmission lines
- Near transformers
- In areas surrounding apartment buildings or residential construction sites, when there are nearby power lines or substation facilities
3) Classification of Environmental Magnetic Fields
- Direct Current Magnetic Fields
Magnetic fields leaking from permanent magnet applications (such as speakers), magnetic fields generated by direct current from lightning strikes or welding machines, or strong electromagnets (such as lifting magnets), as well as geomagnetic fields.
- Alternating Current Magnetic Fields
Magnetic fields from power transmission lines and distribution equipment at commercial frequencies.
- Variable Magnetic Fields
Transient magnetic field changes due to the passage of trains or vehicles, and disturbances in magnetic fields caused by the operation or shutdown of electrical equipment and devices.
