Lub luag haujlwm, nta, thiab kev siv ntawm Polarographic Dissolved Oxygen Sensors

Txoj Cai Ua Haujlwm

Polarographic dissolved oxygen sensors ua haujlwm raws li cov txheej txheem electrochemical, feem ntau siv Clark electrode. Lub sensor muaj ib tug kub cathode, ib tug silver anode, thiab ib tug tshwj xeeb electrolyte, tag nrho cov nyob rau hauv ib tug xaiv permeable membrane.

Thaum ntsuas, oxygen diffuses los ntawm daim nyias nyias mus rau hauv lub sensor. Ntawm cathode (kub electrode), oxygen undergoes txo, thaum lub anode (silver electrode), oxidation tshwm sim. Cov txheej txheem no ua kom muaj qhov sib txawv tam sim no sib npaug rau cov pa oxygen concentration hauv cov qauv, ua rau kev ntsuas meej.

3. Low Maintenance Requirements:
   • Cov qauv tsim niaj hnub no feem ntau tsis tas yuav hloov cov electrolyte tsis tu ncua, txo cov nqi tu thiab siv zog mus ntev. Txawm li cas los xij, lub sij hawm calibration thiab hloov daim nyias nyias tseem tsim nyog.
4. Strong Stability thiab Anti-Interference Capability:
   • Kev xaiv permeable membrane zoo cais cov impurities thiab cov kab mob, ua kom ruaj khov thiab txhim khu kev ntsuas.
5. Automatic Temperature Compensation:
   • Feem ntau cov sensors muaj xws li ib tug built-in kub sensor rau tsis siv neeg kub them nyiaj, kho cov kev ntsuas uas raug tshwm sim los ntawm kub hloov.
6. Smart thiab Integrated Design:
   • Ntau lub sensors tau nruab nrog kev sib txuas lus sib txuas lus (xws li RS485) thiab txhawb nqa cov txheej txheem kev cai (xws li Modbus), ua kom muaj kev sib koom ua ke rau hauv automation tswj systems thiab IoT platforms rau kev saib xyuas cov ntaub ntawv nyob deb.

Daim ntawv thov Scenario

Polarographic yaj oxygen sensors tau dav siv thoob plaws ntau yam kev lag luam:

1. Cov txheej txheem kev lag luam thiab kev kho dej:
   • Boiler Feedwater Saib Xyuas: Qhov tseem ceeb hauv kev lag luam xws li lub zog tsim hluav taws xob, tshuaj lom neeg, thiab metallurgy, qhov twg cov pa oxygen ntau dhau tuaj yeem ua rau muaj kev xeb loj ntawm cov kav hlau thiab cov khoom siv.
   • Kev kho dej khib nyiab thiab kev saib xyuas cov dej pov tseg: Cov pa oxygen tau cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov kab mob hauv nroog thiab cov txheej txheem kho dej khib nyiab.
   • Semiconductor thiab Ultrapure Dej Ntau Lawm: Cov dej purity siab hauv cov khoom siv hluav taws xob tsim nyog yuav tsum tau saib xyuas cov kab hauv cov pa oxygen.
2. Environmental Monitoring thiab Scientific Research:
   • Dej Ntog Dej, Dej Dej, thiab Lake Zoo Saib Xyuas: Cov pa oxygen yaj yog qhov qhia txog qhov tseem ceeb ntawm cov dej huv tus kheej thiab kev noj qab haus huv.
   • Aquaculture: Kev saib xyuas lub sijhawm tiag tiag ntawm cov pa oxygen yaj pab tiv thaiv hypoxia hauv cov kab mob hauv dej, txhim kho kev ua liaj ua teb.
3. Biotechnology thiab Pharmaceutical Industries:
   • Dissolved oxygen concentration yuav tsum tau tswj kom meej nyob rau hauv bioreactors (xws li, fermentation thiab cell kab lis kev cai) los xyuas kom meej kev loj hlob tej yam kev mob rau microorganisms los yog hlwb.
4. Khoom noj khoom haus thiab dej haus kev lag luam:
   • Cov qib oxygen yaj hauv cov khoom tuaj yeem cuam tshuam cov khoom saj, xim, thiab lub neej txee, ua rau kev saib xyuas qhov tseem ceeb thaum tsim khoom.
