Ho kenya
- Khetha karolo e nepahetseng ea stem bakeng sa ho kenya sensor. Etsa bonnete ba hore sekhahla sa ho phalla ha sap kutung ha se fete 12 ml / h. Khakanyo e boima e ka etsoa ho nahanoa ka sekhahla sa phepelo se lekanang le 1.5 ml/h ka lisekoere tsa decimeter ea bokaholimo ba makhasi.
- Bula sensor ka bophara ho lekana ho e beha holim'a kutu. Etsa bonnete ba hore letšoao le khubelu la tataiso le tsamaisana le phallo e eang holimo.
- Etsa bonnete ba hore sensor e behiloe ka thata 'me ha e khone ho thellela kapa ho sotha ka tšebeliso ea matla a bonolo.
- Koahela sensor ka hloko ka likarolo tse peli kapa tse tharo tsa foil ea aluminium e le ho sireletsa sensor ho litlamorao tsa mocheso o kantle. Hoa hlokahala ka ho feletseng bakeng sa litekanyo tse ka tšeptjoang.
- Ho fana ka boemo bo tiileng ba sensara likutung tse bophara bo ka tlase ho 4 mm bakeng sa SF-4M le 8 mm bakeng sa SF-5M, kenya rabara ea foam-rabara karolong e ka hare e se nang letho ea kutlo joalokaha e bontšitsoe ka tlase.
Ho Khetha Litholoana
- Li-sensor tsa SF li na le liphello tse latelang tsa analog le digital: Analog: 0 ho 2 Vdc, kapa 0 ho 20 mA, kapa 4 ho 20 mA, e khethiloeng ke jumpers;
- 0Digital: UART-TTL, boikhethelo: RS-232, RS-485 Modbus RTU, SDI12, e khethiloeng ke li-switches tse nyane.
Ke tlhahiso e le 'ngoe feela ea analog le tlhahiso e le 'ngoe ea dijithale e ka bang teng ka nako.
Maemo a loketseng a li-jumpers le li-switches a hlalositsoe ka tlase.
Taba ea pele, ka kopo khetha thapo e nepahetseng bakeng sa ho hokela sensor ho datalogger. Thapo e tlameha ho ba chitja ka lithapo tse 4 bakeng sa lihlahisoa tsa analoge le tsa dijithale. Bophahamo bo boholo ba mohala ke 6.5 mm. Bolelele ba cable ha bo na ho feta 10 m bakeng sa liphetho tsohle ntle le liphetho tsa hajoale, SD112 e ka bang 1 km maximal length, le RS-485 e ka bang 1.2 km maximal length.
Tsamaisa thapo ka sekoting se loketseng ebe u hokela ho latela tlhahiso eo u e batlang:
- Lithapo tsa motlakase ho XT1
- Tlhahiso ea analoge ho XT6
- Tlhahiso ea dijithale ho ikopanye le e nepahetseng ea terminal XT2-XT5
Khetha mofuta o lakatsehang oa tlhahiso ea dijithale ka ho sebelisa sesebelisoa sa khetho joalo ka fol

Ha o sebelisa tlhahiso ea analog, mokhethoa oa dijithale a ka ba maemong afe kapa afe ntle le SDI12!
Khetha mofuta o lakatsehang oa tlhahiso ea analog ka boemo bo loketseng ba jumper XP1, XP4 ka tsela e latelang:
0 ho isa ho 2 Vdc Tlohela ho XP4
4 ho isa ho 20 mA Tlohela ho XP1
0 ho isa ho 20 mA Ha ho jumper
Jumper XP2 e hlophiselitsoe ho emisa tlhahiso ea RS-485 haeba sensor e le ketane ea ho qetela moleng.
Jumper XP3 e fetola boemo ba tlhahiso ea UART TTL. Haeba jumper e behiloe, voltagtekanyo ea e ke 3.3 V; haeba ho se na jumper, voltagtekanyo ea e ke 5 V.
Khokahano
Sephetho sa Analog
Ha o sebelisa liphetho tsa analog, mehato eohle e ka khonehang ea ho fokotsa liphoso tsa lisebelisoa e tla etsoa:
- Lithapo tse hlahlobiloeng.
- Lithapo tse nang le impedance e tlase.
- Lithapo tse sothehileng.
- Ho hlophisoa ha lets'oao ka maqhubu a tlase a cutoff.
- Phepelo ea motlakase e ikhethileng le data logger. Filtration ea dijithale ea lets'oao.

Lintlha tsa bohlokoa:
- Khokahano ea li-sensor e kopana le litlhoko tsa maemo a EIA RS-485 (TIA-485), 'me e tla hokahana ka nepo. Ke habohlokoa ho hlokomela hore mohanyetsi oa ho felisa, haeba ho hlokahala, o hokahane ke jumper XP2.
- EIA RS-485 Specification e tšoaea litheminale tsa data e le “A” le “B”, empa bahlahisi ba bangata ba ngola litheminale tsa bona e le “+” le “-“. Ka tloaelo ho lumeloa hore "-" terminal e lokela ho amahanngoa le "A", le "+" ho ea "B". Ho khutlisetsa polarity ho ke ke ha senya sesebelisoa sa 485, empa se ke ke sa buisana.
- Bakeng sa lithapo tsa fatše tse sebetsang hantle tsa lisebelisoa tsohle tse hokahaneng le bese ea RS-485 li tlameha ho hokahana hammoho. Ha ho sebelisoa phepelo ea motlakase e arohaneng, terminal ea eona ea fatše (“minus”) e tlameha ho hokelloa moleng o ka tlase oa bese.
- Ka kopo, hokela lithapo tsa fatše pele ho likhokahano tse ling kaofela.
