RS485 isivamvo sokunyakama komhlaba esikrelekrele senkqubo yokubeka iliso yomhlaba
Inkcazo yeMveliso
Ukumiselwa ngokukhawuleza kwezivamvo zokunyakama komhlaba kwezolimo kuyafuneka kwiinkalo zokugada ukugcinwa komhlaba namanzi, ukujongwa kwamanzi omhlaba, inkqubo yokubeka iliso yomhlaba ekrelekrele, ukuchaneka kwemveliso yezolimo kunye nokunkcenkceshela.
Iindlela zokumisela ziquka indlela yokomisa, indlela ye-ray, indlela yepropathi ye-dielectric, indlela ye-nuclear magnetic resonance, indlela yetracer yokwahlula kunye nendlela ye-remote sensing.Phakathi kwabo, indlela yeempawu ze-dielectric yimilinganiselo engathanga ngqo esekelwe kwiimpawu ze-dielectric zomhlaba, ezinokuqonda umlinganiselo okhawulezayo nongowonakaliyo wokufuma komhlaba.
Ngokukodwa, isivamvo somhlaba esilumkileyo sinokwahlulwa sibe ngumgaqo-siseko we-TDR wokubonisa ixesha kunye nomgaqo-siseko weFDR wokubonisa rhoqo.
Uthotho lwe-MTQ-11SM isivamvo sokunyakama komhlaba yinzwa ye-dielectric esekelwe kumgaqo wokubonisa rhoqo i-FDR.Inokulinganisa utshintsho lwe-capacitance kwi-sensor kwi-100MHz frequency ukulinganisa i-dielectric constant ye-medium yokufaka.Ngenxa yokuba i-dielectric constant of water iphezulu kakhulu (80), umhlaba (3-10).
Ngoko ke, xa isiqulatho sokufuma emhlabeni sitshintsha, idielectric constant yomhlaba nayo itshintsha kakhulu.Olu chungechunge lokunkcenkceshela inzwa yokufuma kunciphisa impembelelo yokutshintsha kobushushu kumlinganiselo.Itekhnoloji yedijithali kunye nezinto ezihlala zihlala zamkelwa, ezinokuchaneka kokulinganisa okuphezulu kunye neendleko eziphantsi.Inzwa inokuqhubeka nokubeka iliso kumxholo wamanzi kwiisampuli ezininzi zeesampulu kunye nobunzulu bomhlaba ohlukeneyo ixesha elide.
Ezona mpawu
● Ukulinganisa umthamo wamanzi omthamo womhlaba kuluhlu lomthamo wama-200 cm ojikeleze umsinga
● Uyilo lwesekethe ye-100 MHz kwinzwa yokufuma komhlaba
● Uvakalelo oluphantsi kumhlaba onetyuwa eninzi kunye nomhlaba obambeneyo
● Ukhuseleko oluphezulu (IP68) lokungcwaba ixesha elide emhlabeni
● Ukunikezelwa kwamandla ombane obanzi, ukulungiswa okungahambi kakuhle, ukuchaneka okuphezulu kunye nokuhambelana
● Ubungakanani obuncinci, ubunzima obulula kunye nokufakwa lula
● I-anti-lighting enamandla, i-frequency-cut interference design kunye nekhono lokuchasana ne-jamming
● Ukubuyisela umva kunye noKhuseleko olugqithisileyo, uKhuseleko lwangoku lokuMida (Isiphumo sangoku)
