Bio Instruments SF-M Series Sap Flow Sensors
Intshayelelo
Iinzwa ze-SF zenzelwe ukubeka iliso kwiinguqu ezihambelana nesantya sokuhamba kwe-sap kwi-petiole yeqabunga okanye ihlumela elincinci. Isivamvo senzwa senziwa njengesilinda esigoqekayo esigoqekayo.
Isifudumezi esilayishwe entwasahlobo kunye neeperi ze-bead thermistors zifumaneka ngaphakathi kwicylinder.
I-conditioner yesignali inika amandla e-heater kunye ne-conditioning ye-output signal.
Zonke iisensonsi zohlobo lwe-SF zivavanywa kwi-hose ezaliswe ngamanzi ngaphakathi kwinqanaba lokulinganisa eliqikelelweyo le-12 ml / h.
I-probe ixhunywe ngentambo eqhelekileyo yemitha ye-1 kwibhokisi engenamanzi kunye ne-signal conditioner ngaphakathi. Ubude bentambo yokuphuma kufuneka bucaciswe kwi-derif efunekayo.
Isiphumo: I-analog ye-linear output (ekhethiweyo) 0 ukuya kwi-2 Vdc, 4 ukuya ku-20 mA, 0 ukuya ku-20 mA.
Ujongano: UART-TTL, ukukhetha: RS-232, RS-485 Modbus RTU, SDI12.
Ukuhlohla
- Khetha indawo efanelekileyo yesikhondo yokuhlohla inzwa. Qinisekisa ukuba izinga lokugeleza kwencindi kwisiqu alidluli kwi-12 ml/h. Uqikelelo olurhabaxa lunokwenziwa kucingwa ukuba umyinge wokuphefumla ulingana ne-1.5 ml/h nge-decimeter yesikwere somphezulu wamagqabi.
- Vula inzwa ebanzi ngokwaneleyo ukuze uyibeke kwisiqu. Qinisekisa ukuba uphawu lwesalathiso olubomvu luyahambelana nokuya phezulu.
- Qinisekisa ukuba i-sensor ibekwe ngokuqinileyo kwaye ayikwazi ukutyibilika okanye ukujija ngokusetyenziswa kwamandla athambileyo.
- Gquba ngononophelo inzwa kunye neengqimba ezimbini okanye ezintathu ze-aluminium foil ukwenzela ukukhusela inzwa kwimiphumo yokushisa yangaphandle. Kuyimfuneko ngokupheleleyo kwimilinganiselo ethembekileyo.
- Ukubonelela ngokumiswa okuqinileyo kwenzwa kwiziqu ezinobubanzi obungaphantsi kwe-4 mm ye-SF-4M kunye ne-8 mm ye-SF-5M, faka ibha yerabha enogwebu kwindawo engenanto yangaphakathi yenzwa njengoko kubonisiwe ngezantsi.
Ukukhetha Iziphumo
- Iinzwa ze-SF zinezi ziphumo zilandelayo ze-analog kunye nedijithali: I-Analog: i-0 ukuya kwi-2 Vdc, okanye i-0 ukuya kwi-20 mA, okanye i-4 ukuya kwi-20 mA, ekhethwe yi-jumpers;
- 0Digital: UART-TTL, ozikhethelayo: RS-232, RS-485 Modbus RTU, SDI12, ekhethwe micro-switshi.
Kuphela imveliso ye-analog enye kunye nemveliso enye yedijithali enokuthi isebenze ngexesha.
Izikhundla ezifanelekileyo ze-jumpers kunye nokutshintsha zichazwe ngezantsi.
Okokuqala, nceda ukhethe intambo yokuphuma ekunene yokudibanisa i-sensor kwi-datalogger. Intambo kufuneka ibe yingqukuva kunye neengcingo ezi-4 ze-analog kunye ne-digital outputs. Ubukhulu obukhulu bentambo yi-6.5 mm. Ubude bentambo abuyi kudlula i-10 m kuzo zonke iziphumo ngaphandle kweziphumo zangoku, i-SD112 malunga ne-1 km ubude obuninzi, kunye ne-RS-485 malunga ne-1.2 km ubude obuninzi.
Qhuba intambo ngokungena kwindawo efanelekileyo kwaye uqhagamshele ngokwemveliso oyifunayo:
- Iingcingo zamandla ukuya kwi-XT1
- Imveliso ye-analog kwi-XT6
- Imveliso yedijithali kuqhagamshelwano olufanelekileyo lwe-terminal XT2-XT5
Khetha uhlobo olufunwayo lwemveliso yedijithali ngokusebenzisa umkhethi wokutshintsha njengefol
RS-232 RS-485 SDI12 UART TT
Xa usebenzisa imveliso ye-analog, umkhethi wedijithali unokuba kuyo nayiphi na indawo ngaphandle kwe-SDI12!
Khetha uhlobo olufunwayo lwemveliso ye-analog ngendawo efanelekileyo ye-jumper XP1, XP4 ngolu hlobo lulandelayo:
0 ukuya 2 Vdc Umtsi kwi-XP4
4 ukuba 20 mA Umtsi kwi-XP1
0 ukuba 20 mA Akukho jumper
I-Jumper XP2 isetelwe ukuphelisa imveliso ye-RS-485 ukuba i-sensor yitsheyini yokugqibela emgceni.
Jumper XP3 itshintsha umgangatho we UART TTL output. Ukuba i-jumper iseti, i-voltaginqanaba le-e yi-3.3 V; kwimeko yokuba akukho jumper, voltaginqanaba le-e ngu-5 V.
Uqhagamshelwano
Imveliso ye-analog
Xa usebenzisa iziphumo ze-analog, onke amanyathelo anokwenzeka okunciphisa iimpazamo zezixhobo ziya kwenziwa:
- Iintambo ezivaliweyo.
- Iintambo ezine-impedance ephantsi.
- Iintambo eziphothiweyo.
- Ukuhluzwa kwesignali kunye ne-low cutoff frequency.
- Unikezelo lwamandla lwalodwa kunye nedatha yokungena. Ukuhluzwa kwedijithali kophawu.
Umyalelo woqhagamshelo lweziphumo zedijithali
- Umhlaba
- Iingcingo zomqondiso
- Amandla 7 ukuya 30 Vdc
RS-485
Amanqaku abalulekileyo:
- Ujongano lwezinzwa luyahlangabezana neemfuno zomgangatho we-EIA RS-485 (TIA-485), kwaye iya kudityaniswa ngokufanelekileyo. Kubalulekile ukuba uqaphele ukuba i-resistor yokuphelisa, ukuba kuyimfuneko, idibaniswe yi-jumper XP2.
- I-EIA RS-485 Specification ibhala iitheminali zedatha njengo-“A” no-“B”, kodwa abavelisi abaninzi babhala iitheminali zabo njengo-“+” kunye no-“-“. Kuyavunywa ngokuqhelekileyo ukuba i-terminal "-" kufuneka iqhagamshelwe kumgca "A", kunye ne "+" kumgca "B". Ukuguqula i-polarity akuyi konakalisa isixhobo se-485, kodwa ayiyi kunxibelelana.
- Ukuze zisebenze ngokufanelekileyo iingcingo ezisemhlabeni zazo zonke izixhobo eziqhagamshelwe kwibhasi ye-RS-485 kufuneka zidityaniswe kunye. Kwimeko yokusetyenziswa kombane ohlukeneyo, i-terminal yayo yomhlaba ("minus") kufuneka iqhagamshelwe kumgca osezantsi webhasi.
- Nceda uqhagamshele iingcingo zomhlaba phambi kwazo zonke ezinye iindibano.
