Kodi sensa ya nthaka ndi chiyani?

Chinyezi cha dothi chimatanthauza chinyezi cha nthaka. Paulimi, zinthu zomwe zili m'nthaka sizingatengedwe mwachindunji ndi mbewu zokha, ndipo madzi a m'nthaka amagwira ntchito ngati zosungunulira kuti asungunuke.nthaka chinyezikupyolera mu mizu yawo, kupeza zakudya ndi kulimbikitsa kukula.Mu ndondomeko ya kukula kwa mbeu ndi chitukuko, chifukwa cha mitundu yosiyanasiyana, zofunikira za kutentha kwa nthaka, madzi amadzi ndi mchere zimakhalanso zosiyana. ndi zoyezera chinyezi m'nthaka, ndizofunikira pakuwunika zachilengedwe.

Ogwira ntchito zaulimi amawadziwa bwinomasensa chinyezi nthaka, koma pali zovuta zambiri pakusankha ndi kugwiritsa ntchito zowunikira chinyezi m'nthaka.Nawa mafunso odziwika bwino okhudza zowunikira chinyezi m'nthaka.

Ma sensor omwe amagwiritsidwa ntchito kwambiri pamsika ndi TDR nthaka chinyezi sensor ndi FDR nthaka chinyezi sensor.

1. Mfundo yogwira ntchito

FDR imayimira frequency domain reflection, yomwe imagwiritsa ntchito mfundo ya electromagnetic pulse.Dothi lowoneka ngati dielectric (ε) limayesedwa molingana ndi kuchuluka kwa mafunde a electromagnetic kufalikira pakati, ndipo kuchuluka kwa madzi m'nthaka (θv) kumapezeka.Sensa ya chinyezi cha nthaka ya HENGKO imatengera mfundo ya FDR, ndipo malonda athu ali ndi ntchito yabwino yosindikizira, yomwe imatha kukwiriridwa mwachindunji m'nthaka kuti igwiritsidwe ntchito, ndipo sichikuwonongeka.Kulondola kwa kuyeza kwakukulu, magwiridwe antchito odalirika, kuonetsetsa kuti magwiridwe antchito abwinobwino, kuyankha mwachangu, kuyendetsa bwino kwambiri kwa data.

TDR imatanthauza chiwonetsero cha nthawi, chomwe ndi mfundo yodziwika bwino yozindikira chinyezi chanthaka.Mfundo yake ndi yakuti ma waveform pa mizere yopatsirana yosagwirizana amawonekera.Mawonekedwe a waveform pamtundu uliwonse pamzere wopatsira ndi mawonekedwe apamwamba a mawonekedwe oyambira komanso mawonekedwe owonekera.Zida za TDR zili ndi nthawi yoyankha pafupifupi masekondi 10-20 ndipo ndizoyenera kuyeza zam'manja ndikuwunika malo.

2. Kodi kutulutsa kwa sensa ya chinyezi cha HENGKO ndi chiyani?

Mtundu wamagetsi Mtundu wamakono RS485 mtundu

Mphamvu yogwira ntchito 7 ~ 24V 12 ~ 24V 7 ~ 24V

Kugwira ntchito panopa 3～5mA 3～25mA 3～5mA

Chizindikiro chotulutsa Chizindikiro: 0～2V DC (0.4 ~ 2V DC ikhoza kusinthidwa) 0～20mA, (4～20mA ikhoza kusinthidwa) protocol ya MODBUS-RTU

HENGKO akuwonetsa kuti mfundo zotsatirazi ziyenera kutsatiridwa mukayika zomvera za chinyezi m'nthaka:

1. Kuyika kwa sensa yoyima: Lowetsani sensa ya madigiri 90 molunjika m'nthaka kuti iyesedwe.Osagwedeza sensa panthawi yoyikapo kuti mupewe kupindika ndikuwononga sensor sensor.

2. Kuyika kopingasa kwa masensa angapo: Ikani masensa m'nthaka kuti ayesedwe mofanana.Njirayi imagwiritsidwa ntchito pozindikira chinyezi cha dothi la multilayer.Osagwedeza sensa pakuyika kuti mupewe kupindika kafukufuku wa sensor ndikuwononga singano yachitsulo.

3. Ndi bwino kusankha nthaka yofewa kuti muyikemo.Ngati mukuwona kuti m'nthaka yoyesedwa muli chotupa cholimba kapena chachilendo, chonde sankhaninso malo omwe nthakayo yayesedwa.

4. Pamene sensa ya nthaka imasungidwa, pukutani singano zitatu zosapanga dzimbiri ndi mapepala owuma a mapepala, kuwaphimba ndi thovu, ndi kuwasunga pamalo ouma a 0-60 ℃.

Zathunthaka chinyezi kachipangizounsembe ndondomeko ndi losavuta, palibe chifukwa ganyu unsembe akatswiri, kupulumutsa ntchito cost.The mankhwala ndi oyenera madzi opulumutsa ulimi ulimi wothirira, wowonjezera kutentha, maluwa ndi ndiwo zamasamba, udzu ndi msipu, muyeso liwiro nthaka, kulima mbewu, kuyesera sayansi, mafuta apansi panthaka, mapaipi a gasi ndi kuwunika kwa dzimbiri kwa mapaipi ndi minda ina.Mwachizoloŵezi, mtengo wa unsembe wa sensa zimadalira dera la malo oyezera ndi ntchito yomwe yapindula.Kodi muyenera kudziwa kuchuluka kwa masensa a chinyezi munthaka omwe mukuyenera kukhazikitsa pamalo oyezera?Kodi chingwe pakati pa masensa ndi nthawi yayitali bwanji?Kodi mukufuna zowongolera zina kuti mugwiritse ntchito zowongolera zokha?Mukamvetsetsa zovutazi, mutha kusankha malinga ndi zosowa zanu kapena kulola gulu laukadaulo la HENGKO kuti likusankhireni zinthu ndi ntchito zoyenera.
