Umza ophantsi we-Electromagnetic Field Active Shielding
Inkqubo ye-MRI sisixhobo sokuxilonga esichanekileyo esichanekileyo, esineemfuno eziphezulu zokusingqongileyo. Isiginali ye-NMR sisignali ebuthathaka kakhulu, enokuthi ichaphazeleke kuphazamiseko lwangaphandle. Ngenxa yoko, iinkqubo zeMRI zihlala zifuna ukuxhotyiswa ngeekheji zeFaraday (amagumbi okhuselo) ukwahlula uphazamiseko lweRF lwangaphandle ekungeneni kwinkqubo. Nangona kunjalo, ikheji yeFaraday inothintelo olungcono lwebhendi yamaza kanomathotholo, kwaye isiphumo sokukhusela isantya esisezantsi silinganiselwe. Ngokukodwa ukufakwa kweenkqubo ze-MRI kufuphi ne-subways, izitimela, ii-transformers ezinkulu, i-elevators, iintambo zokuhambisa amandla, njl. Akufuneki kuphela ukuba i-Faraday cage iqulunqwe, kodwa kunye nenkqubo yokukhusela esebenzayo kufuneka iqulunqwe ukwenza inkqubo ye-MRI ihlangabezane neemfuno zokuxilonga. .
I-CSJ-ASH yinkqubo yokukhusela esebenzayo ye-electromagnetic ephantsi-frequency ephantsi ephuhliswe ngu-Ningbo Chuanshan Jia Electromechanical Co., Ltd. Iyakwazi ukukhusela ngokufanelekileyo amasimi ombane we-DC, i-50Hz / 60Hz amasimi ombane we-electromagnetic abangelwa yi-subways, oololiwe, iitram, iintambo zothumelo, izixhobo ze-transformer, ii-elevators, njl. njl. I-CSJ-ASH iquka amacandelo amathathu amakhulu: i-fluxgate i-high-precision probe, i-host, kunye ne-coil yokukhusela. Iprobe ye-fluxgate ephezulu echanekileyo inokuva ukuphazamiseka kwentsimi ye-electromagnetic, kwaye ivelise umqondiso ohambelanayo wombane wokuhambisa kumamkeli. Emva kokucubungula, umamkeli ukhupha umva wangoku olandela ngexesha lokwenyani, kwaye langoku livelisa indawo yemagnethi ebuyela umva kwikhoyili ekhuselayo ukurhoxisa uphazamiseko lwemagnethi, ngaloo ndlela kuqondwe ukukhuselwa okusebenzayo kwemimandla ye-electromagnetic ephantsi-frequency.
