Chii chinonzi SAR yekuongorora?

SAR, inozivikanwawo seSpecific Absorption Rate, inoreva masaisai emagetsi anotorwa kana kupedzwa payuniti yakawanda yematishu evanhu. Chikwata iW/Kg kana mw/g. Inoreva kuyerwa kwesimba kunyudzwa kwesimba remuviri wemunhu kana rakafumurwa kune redhiyo frequency electromagnetic minda.
Kuongororwa kweSAR kunonyanya kunangwa kune zvigadzirwa zvisina waya zvine antenna mukati mechinhambwe che20cm kubva mumuviri wemunhu. Inoshandiswa kutidzivirira kubva kumidziyo isina waya inodarika kukosha kweRF yekufambisa. Haasi ese asina waya ekutapurirana antenna mukati mechinhambwe che20cm kubva mumuviri wemunhu anoda kuongororwa kweSAR. Nyika yega yega ine imwe nzira yekuyedza inonzi MPE ongororo, yakavakirwa pazvigadzirwa zvinosangana nemamiriro ari pamusoro asi zvine simba rakaderera.

SAR yekuyedza chirongwa uye nguva yekutungamira:
Kuongororwa kweSAR kunonyanya kuve nezvikamu zvitatu: kusimbiswa kwesangano, kusimbiswa kwehurongwa, uye kuyedzwa kweDUT. Kazhinji kutaura, vashandi vekutengesa vanozoongorora iyo yekuyedza yekutungamira nguva zvichienderana nekutsanangurwa kwechigadzirwa. Uye frequency. Uye zvakare, zvinodikanwa kuti utarise nguva yekutungamira yekuyedza mishumo uye chitupa. Iyo yakanyanya kuyedzwa kazhinji inodiwa, iyo yakareba nguva yekuyedza ichadikanwa.
Xinheng Detection ine SAR yemidziyo yekuyedza iyo inogona kuzadzisa zvinodiwa zvekuyedzwa zvevatengi, kusanganisira nekukasira purojekiti yekuyedza zvinodiwa. Uye zvakare, iyo frequency yekuyedza inovhara 30MHz-6GHz, inenge ichivhara uye inokwanisa kuyedza zvigadzirwa zvese pamusika. Kunyanya kukurumidza kukurumbira kwe5G yezvigadzirwa zveWi Fi uye yakaderera-frequency 136-174MHz zvigadzirwa pamusika, Xinheng Testing inogona kubatsira vatengi kunyatsogadzirisa nyaya dzekuyedza uye chitupa, zvichiita kuti zvigadzirwa zvipinde mumusika wepasirese.

BTF Testing Lab inzvimbo yekuyedza yakatenderwa neChina National Accreditation Service yeConformity Assessment (CNAS), nhamba: L17568. Mushure memakore ebudiriro, BTF ine electromagnetic inoenderana murabhoritari, isina waya yekutaurirana murabhoritari, SAR rabhoritari, kuchengetedza marabhoritari, kuvimbika marabhoritari, marabhoritari yekuyedza bhatiri, kuongororwa kwemakemikari uye mamwe marabhoritari. Iine yakakwana electromagnetic inoenderana, redhiyo frequency, kuchengetedzwa kwechigadzirwa, kuvimbika kwezvakatipoteredza, kuongororwa kutadza kwezvinhu, ROHS / REACH uye humwe hunyanzvi hwekuyedza. BTF Testing Lab yakashongedzerwa nehunyanzvi uye yakakwana yekuyedza zvivakwa, timu ine ruzivo yekuyedza uye nyanzvi dzezvitupa, uye kugona kugadzirisa kwakasiyana kwakaoma kuyedzwa uye matambudziko etifiketi. Isu tinoomerera kune inotungamira misimboti ye "kurongeka, kusarerekera, kurongeka, uye kuomarara" uye tinonyatso kutevedzera zvinodiwa ne ISO/IEC 17025 yekuyedza uye calibration laboratory manejimendi system yekutonga kwesainzi. Takazvipira kupa vatengi basa remhando yepamusoro. Kana uine mibvunzo, ndapota inzwa wakasununguka kutibata nesu chero nguva.
