MRI system ndeye yakakwirira-chaiyo imaging diagnostic equipment, ine zvakakwirira zvinodiwa zvenzvimbo yekuisa. Chiratidzo cheNMR chiratidzo chisina kusimba, chinotapukirwa nekukanganiswa kwekunze. Nekuda kweizvozvo, masisitimu eMRI anowanzoda kuve akashongedzerwa nemakeji eFaraday (makamuri ekudzivirira) kuti abvise kupindira kweRF kwekunze kubva pakupinda muhurongwa. Nekudaro, iyo Faraday cage ine zvirinani attenuation yeredhiyo frequency bhendi, uye kudzivirira kweiyo yakaderera frequency ishoma. Kunyanya pakugadzika kweMRI zvirongwa pedyo ne subways, zvitima, ma transformers makuru, elevator, tambo dzemagetsi ekufambisa, etc. Haisi kungoita kuti Faraday cage igadzirwe, asiwo hurongwa hwekudzivirira hunoita hunofanira kugadzirirwa kuita kuti MRI system isangane nezvinodiwa zvekuongororwa. .

CSJ-ASH inzvimbo yakakwirira-yakaderera-frequency yemagetsi inoshanda shielding system yakagadziridzwa naNingbo Chuanshan Jia Electromechanical Co., Ltd. Inogona kudzivirira zvinobudirira DC electromagnetic fields, 50Hz/60Hz power frequency electromagnetic fields inokonzerwa ne subways, zvitima, tram, tambo dzekutumira, midziyo yetransformer, elevator, nezvimwewo CSJ-ASH ine zvikamu zvitatu zvikuru: fluxgate high-precision probe, host, uye shielding coil. Iyo yakakwira-chaiyo fluxgate probe inogona kuona kukanganiswa kwenzvimbo yemagetsi emagetsi, uye kuburitsa chiratidzo chemagetsi chinoenderana kuti chitumire kune anotambira. Mushure mekugadzirisa, mugadziri anoburitsa reverse ikozvino inotevera munguva chaiyo, uye ikozvino inogadzira reverse magineti mune inodzivirira coil kudzima kukanganiswa kwemagineti, zvichibva zvaona kushanda kwekudzivirira kwepasi-frequency electromagnetic minda.
