ʻO ka ʻōnaehana MRI kahi mea hana diagnostic imaging kiʻekiʻe, nona nā koi kiʻekiʻe no ke kaiapuni hoʻonohonoho. ʻO ka hōʻailona NMR he hōʻailona nāwaliwali loa, hiki ke hoʻopilikia i waho. ʻO ka hopena, pono e hoʻolako pinepine ʻia nā ʻōnaehana MRI me nā cages Faraday (nā lumi pale) e hoʻokaʻawale i ka hoʻopili RF waho mai ke komo ʻana i ka ʻōnaehana. Eia nō naʻe, ʻoi aku ka maikaʻi o ka pā o Faraday no ka lekiō alapine, a ʻo ka hopena pale no ka haʻahaʻa haʻahaʻa he palena iki. Maikaʻi no ka hoʻokomo ʻana i nā ʻōnaehana MRI kokoke i nā subways, nā kaʻaahi, nā transformers nui, nā elevators, nā kaula uila uila, a me nā mea ʻē aʻe. .

CSJ-ASH mea he kiʻekiʻe-hana haʻahaʻa haʻahaʻa electromagnetic kahua ikaika shielding nenoaiu i hoʻomohalaʻia e Ningbo Chuanshan Jia Electromechanical Co., Ltd. Ua hiki pono pale DC electromagnetic mahina, 50Hz / 60Hz mana alapine electromagnetic kahua i hoʻokumu 'ia e subways, kaʻaahi, trams, nā kaula hoʻouna, nā mea hoʻololi, nā mea hoʻokiʻekiʻe, a me nā mea ʻē aʻe. Aia ʻo CSJ-ASH i ʻekolu mau mea nui: fluxgate high-precision probe, host, and shielding coil. Hiki i ka ʻimi fluxgate kiʻekiʻe ke ʻike i ka hoʻopili ʻana o ke kahua electromagnetic kaiapuni, a hoʻopuka i ka hōʻailona uila kūpono e hoʻouna i ka host. Ma hope o ka hoʻoponopono ʻana, hoʻopuka ka mea hoʻokipa i kahi au hou e hahai ana i ka manawa maoli, a ke hana nei ke ʻano i kahi kahua magnetic reverse i loko o ka coil pale e hoʻopau i ke kahua magnetic interference, a laila e ʻike ai i ka pale ikaika o nā pā electromagnetic haʻahaʻa.
