I-RS485 inzwa yomswakama womhlabathi ehlakaniphile yohlelo lokuqapha umhlabathi oluhlakaniphile
Incazelo Yomkhiqizo
Ukunqunywa ngokushesha kwezinzwa zokuswakama kwenhlabathi kwezolimo kuyadingeka emkhakheni wokuqapha ukongiwa kwenhlabathi namanzi, ukuqapha amanzi angaphansi komhlaba, uhlelo lokuqapha umhlabathi oluhlakaniphile, ukukhiqizwa kwezolimo ngokunemba kanye nokunisela.
Izindlela zokunquma zihlanganisa indlela yokomisa, indlela ye-ray, indlela yempahla ye-dielectric, indlela ye-nuclear magnetic resonance, indlela yokulandelela okuhlukanisayo kanye nendlela yokuzwa kude.Phakathi kwazo, indlela yesici se-dielectric iyisilinganiso esingaqondile esisekelwe ezintweni ze-dielectric zenhlabathi, engakwazi ukubona ukukala okusheshayo nokungonakalisi komswakama wenhlabathi.
Ngokukhethekile, inzwa yenhlabathi ehlakaniphile ingahlukaniswa ngesimiso se-TDR sokuboniswa kwesizinda sesikhathi kanye nomgomo we-FDR wokubonisa imvamisa.
Inzwa yomswakama wenhlabathi ye-MTQ-11SM iyinzwa ye-dielectric esekelwe kumgomo wokubonisa imvamisa ye-FDR.Ingakwazi ukukala ukuguqulwa kwamandla kunzwa ku-100MHz imvamisa ukukala ukungaguquguquki kwe-dielectric yendawo efakayo.Ngenxa yokuthi i-dielectric constant yamanzi iphakeme kakhulu (80), inhlabathi ingu (3-10).
Ngakho-ke, lapho umswakama emhlabathini ushintsha, i-dielectric constant yenhlabathi nayo ishintsha kakhulu.Lolu chungechunge lwenzwa yomswakama wokunisela lunciphisa ithonya lokushintsha kwezinga lokushisa esilinganisweni.Ubuchwepheshe bedijithali nezinto ezihlala isikhathi eside ziyamukelwa, ezinokunemba kokulinganisa okuphezulu kanye nezindleko eziphansi.Inzwa ingaqapha ngokuqhubekayo okuqukethwe kwamanzi kumasampuli amaningi kanye nokujula kwenhlabathi okuhlukene isikhathi eside.
Izici Eziyinhloko
● Ukulinganisa umthamo wamanzi omthamo wenhlabathi ngobubanzi obungama-200 cm azungeze i-probe
● Idizayini yesekethe engu-100 MHz yenzwa yokuswakama kwenhlabathi
● Ukuzwela okuphansi kusawoti omningi kanye nenhlabathi ehlangene
● Ukuvikelwa okuphezulu (IP68) kokungcwaba isikhathi eside emhlabathini
● Ukunikezwa kwamandla kagesi okubanzi, ukulungiswa okungaqondile, ukunemba okuphezulu nokuvumelana
● Usayizi omncane, isisindo esincane nokufakwa kalula
● Idizayini eqinile yokulwa nombani, idizayini yokunqanyulwa kwemvamisa kanye nekhono lokulwa ne-jamming
● Ukuvikelwa Okuhlehlisiwe Nokweqisa Kwegesi, Ukuvikelwa Kwamanje Okukhawula (Okukhiphayo Kwamanje)
