RS485 smart sensor chinyezi cha nthaka yanzeru yowunikira nthaka
Kufotokozera Kwazinthu
Kutsimikiza kwachangu kwa zowunikira za chinyezi m'nthaka paulimi kumafunika poyang'anira nthaka ndi madzi, kuyang'anira nthaka ya hydrological, njira yanzeru yowunikira nthaka, ulimi waulimi ndi ulimi wothirira.
Njira zowunikira zimaphatikizapo njira yowumitsa, njira ya ray, njira ya dielectric property, nyukiliya magnetic resonance njira, njira yopatukana ndi njira yowonera kutali.Pakati pawo, njira yamtundu wa dielectric ndi muyeso wosalunjika wotengera momwe dothi limagwirira ntchito, zomwe zimatha kuzindikira kuyeza kofulumira komanso kosawononga kwa chinyezi cha nthaka.
Makamaka, kachipangizo kakang'ono ka dothi kamene kamatha kugawidwa mu mfundo ya TDR yowonetsera nthawi komanso mfundo ya FDR.
MTQ-11SM mndandanda wa sensa ya chinyezi cha nthaka ndi sensa ya dielectric yotengera mfundo ya FDR yowonetsera pafupipafupi.Ikhoza kuyeza kusintha kwa mphamvu pa sensa pa 100MHz pafupipafupi kuti muyese kusinthasintha kwa dielectric kwa sing'anga yolowetsa.Chifukwa dielectric nthawi zonse ya madzi ndi yokwera kwambiri (80), nthaka ndi (3-10).
Choncho, chinyezi m'nthaka chikasintha, mphamvu ya dielectric ya nthaka imasinthanso kwambiri.Mndandanda wa sensa yamadzi yothirira madzi amachepetsa mphamvu ya kusintha kwa kutentha pa muyeso.Ukadaulo wa digito ndi zida zolimba zimatengedwa, zomwe zimakhala zolondola kwambiri komanso zotsika mtengo.Sensa imatha kuwunika mosalekeza zomwe zili m'madzi m'magawo ambiri komanso kuya kwa nthaka kwa nthawi yayitali.
Zofunika Kwambiri
● Kuyeza kuchuluka kwa madzi m'nthaka mumtunda wa 200 cm mozungulira pofufuza
● Kupanga kwa 100 MHz dera la sensa ya chinyezi cha nthaka
● Kusamva bwino kwa mchere wambiri komanso dothi lolumikizana
● Chitetezo chachikulu (IP68) cha kuikidwa m'nthaka kwa nthawi yaitali
● Kupereka magetsi ambiri, kuwongolera kopanda mzere, kulondola kwakukulu komanso kusasinthasintha
● Kukula kwakung'ono, kulemera kopepuka komanso kuyika kosavuta
● Mphamvu zotsutsana ndi mphezi, mapangidwe osokoneza pafupipafupi komanso otsutsa-jamming
● Kuteteza Kumbuyo ndi Kuwonongeka Kwambiri, Chitetezo Chochepetsera Pano (Zotuluka Pano)
