Khoom Description
Lub ntsuas hluav taws xob siv rau kev ntsuas dej zoo yog hom khoom siv hluav taws xob tshwj xeeb tsim los ntsuas dej zoo. Nws tuaj yeem ntsuas tus nqi conductivity hauv dej thiab txheeb xyuas qhov tsis xws li cov ntsiab lus ion thiab concentration hauv dej zoo. Lub ntsuas hluav taws xob siv rau kev ntsuas dej zoo yog tsim rau kev saib xyuas thiab tswj cov dej zoo hauv thaj chaw xws li kev tiv thaiv ib puag ncig, dej hiav txwv, thiab hydrology. Nws tseem tuaj yeem saib xyuas cov sijhawm tsis muaj sijhawm xws li cov ntsiab lus ion thiab concentration hauv dej, txhim kho kev ua haujlwm zoo thiab qhov tseeb ntawm kev saib xyuas dej zoo. Nyob rau tib lub sijhawm, cov teeb liab tawm tam sim no lossis 485 kev sib txuas lus tuaj yeem txuas nrog cov khoom siv tswj tsis siv neeg xws li PLC lossis khoos phis tawj kom ua tiav kev tswj tsis siv neeg thiab cov ntaub ntawv xa mus.
Cov neeg siv feem ntau tsis tas yuav kho qhov ntsuas vaj huam sib luag (electronic unit) ntawm lawv tus kheej. Yog tias muaj qhov yuam kev lossis ua haujlwm tsis zoo, thov hu rau peb lub tuam txhab kom kho raws li kev qhia ntawm cov neeg ua haujlwm. Yog tias tus neeg siv muaj lus nug txog qhov ntsuas, lawv tuaj yeem tshem tawm cov kev sib txuas ntawm lub ntsuas hluav taws xob thiab cov hluav taws xob hluav taws xob, thiab txuas lub thawv tiv thaiv mus rau cov khoom siv hluav taws xob sib txuas (Temps) ntawm tus pins 11 thiab 12, nrog rau tus pins 9 thiab 1{ {4}} ntawm ob qho kawg ntawm cov electrode, rau kev simulation pov thawj thiab kev ntxub ntxaug. Ua ntej, teeb qhov kub coefficient ntawm qhov ntsuas rau 0.00% thiab hloov tus nqi raug ntawm conductivity siv cov qauv hauv qab no:
S=106×K/R
Hauv cov qauv, tus nqi conductivity yog nyob rau hauv units ntawm μ S · cm-1
K__ electrode tas li, unit: cm-1
R__ Resistance box nqi, unit: Ω
Piv txwv li, yog tias lub thawv tsis kam siv los nkag rau 10K Ω resistor thiab qhov ntsuas hluav taws xob tsis tu ncua yog teem rau 0.1cm-1, qhov theoretical conductivity nqi S{{4 }} × 0.1/10000=10 μ S · cm-1, thiab qhov txawv ntawm qhov ntsuas ntsuas thiab 10 μ S · cm-1 yuav tsum tsawg dua lossis sib npaug ntawm qhov yuam kev yooj yim. Cov cuab yeej no siv NTC kub coefficient thermistors thiab siv ob lub xaim hluav taws xob rau kev ntsuas qhov kub thiab txias.
Technical Parameters
Cov lus hauv qab no qhia txog kev sib txuas lus ntawm kev tiv thaiv thiab kev ua haujlwm (teeb tsa "tsis" - "kub coefficient" ntawm lub ntsuas rau 0.00%, teeb "automatic mode" rau "tawm" xeev, thiab "electrode tas li" sib raug rau K hauv lub rooj)
