RS485 pūoko makuku oneone atamai mo te punaha aroturuki oneone atamai
Whakaahuatanga Hua
Ko te whakatau tere o te makuku makuku oneone mo te ahuwhenua e hiahiatia ana i roto i nga mara o te tiaki i te oneone me te tiaki wai, te aro turuki i te wai o te oneone, te punaha tirotiro oneone atamai, te mahi ahuwhenua me te irrigation.
Ko nga tikanga whakatau ko te tikanga whakamaroke, te tikanga hihi, te tikanga taonga dielectric, te tikanga resonance autō karihi, te tikanga tracer wehenga me te tikanga mohio mamao.I roto i a raatau, ko te tikanga ahuatanga dielectric he inenga autaki i runga i nga ahuatanga o te dielectric o te oneone, ka taea te mohio ki te tere me te kore-kino o te makuku oneone.
Inaa, ka taea te wehewehe i te pukoro oneone atamai ki te kaupapa TDR whakaata rohe me te kaupapa FDR whakaata auau.
MTQ-11SM raupapa makuku oneone pūoko ko te pūoko dielectric i runga i te parau tumu o te whakaata auau FDR.Ka taea e ia te ine i te huringa o te kaha i runga i te pukoro i te 100MHz auau ki te ine i te taima dielectric o te reo whakauru.Na te mea he tiketike rawa te taima dielectric o te wai (80), he (3-10) te oneone.
No reira, ka huri te makuku i roto i te oneone, ka tino rerekee ano te taunga dielectric o te oneone.Ko tenei raupapa o te pūoko makuku irrigation ka whakaiti i te awe o te huringa pāmahana i runga i te ine.Ka whakamahia te hangarau matihiko me nga rawa roa, he nui te tika o te ine me te utu iti.Ka taea e te pūoko te aro turuki tonu i te ihirangi wai i roto i te maha o nga papa tauira me nga hohonutanga o te oneone rereke mo te wa roa.
Nga waahanga matua
● Te ine i te ihirangi wai ruri o te oneone i roto i te awhe 200 cm te kaha huri noa i te tirotiro
● Hoahoa o te ara iahiko 100 MHz mo te pūoko makuku oneone
● He iti te tairongo i roto i te tote teitei me te oneone whakakotahi
● Te whakamarumaru teitei (IP68) mo te nehua mo te wa roa ki te oneone
● Te tuku ngaohiko whanui, te whakatikatika kore-raina, te tino tika me te rite
● Te rahi iti, te taumaha marama me te whakaurunga ngawari
● He kaha ki te aukati i te uira, te hoahoa pokanoa-tapahi me te kaha ki te aukati
● Parenga Whakamuri me te Ngaohiko, Parenga Whakatepe O Naianei (Putanga O Naianei)
