RS485 mai firikwensin danshi na ƙasa don tsarin kula da ƙasa mai kaifin

Ana buƙatar tantance na'urorin damshin ƙasa da sauri don aikin noma a fagen kula da ƙasa da kiyaye ruwa, sa ido kan yanayin ruwa na ƙasa, tsarin kula da ƙasa mai kaifin baki, daidaitaccen aikin noma da ban ruwa.

Hanyoyin tantancewa sun haɗa da hanyar bushewa, hanyar ray, hanyar kaddarorin dielectric, hanyar faɗaɗa maganadisu ta nukiliya, hanyar rabuwa da hanyar gano nesa.Daga cikin su, hanyar siffa ta dielectric ita ce ma'auni kai tsaye bisa ga kaddarorin dielectric na ƙasa, wanda zai iya gane saurin da rashin lalata ma'aunin danshi na ƙasa.

Musamman, ana iya raba firikwensin ƙasa mai wayo zuwa ƙa'idar TDR ta yankin lokaci da ƙa'idar FDR mai mitar tunani.

MTQ-11SM jerin ƙasa danshi firikwensin ne dielectric firikwensin dangane da ka'idar mita tunani FDR.Yana iya auna canjin capacitance akan firikwensin a mitar 100MHz don auna madaidaicin dielectric na matsakaicin sakawa.Saboda yawan ruwa ya yi yawa (80), ƙasa (3-10).

Saboda haka, lokacin da abun ciki na ƙasa ya canza, dielectric akai-akai na ƙasa shima yana canzawa sosai.Wannan jerin firikwensin danshi na ban ruwa yana rage tasirin canjin zafin jiki akan ma'aunin.Ana ɗaukar fasahar dijital da abubuwa masu ɗorewa, waɗanda ke da daidaiton ma'auni da ƙarancin farashi.Na'urar firikwensin na iya ci gaba da lura da abun cikin ruwa a cikin filaye da yawa na samfuri da zurfin ƙasa daban-daban na dogon lokaci.
