Qhov zoo ntawm kev siv cov thermocouple:
1. Dav qhov kub thiab txias:
Qhov ntsuas kub ntawm cov thermocouple yog los ntawm 0 ° C txog +2200 ° C, nyob ntawm qhov sib txawv thiab cov khoom siv.
2. Muaj zog thiab ruaj khov: thermocouple belongs rau cov khoom siv ruaj khov nrog kev poob siab zoo thiab tsim nyog rau ib puag ncig hnyav hnyav.
3. Cov lus teb ceev ceev: vim tias qhov ntim me me, muaj peev xwm thermal tsawg, cov thermocouple teb rau qhov kub thiab txias hloov ceev, tshwj xeeb tshaj yog thaum lub induction hlws ris sib koom ua ke. Lawv tuaj yeem teb rau qhov kev hloov pauv kub hauv ntau pua milliseconds.
4. Tsis muaj cua sov nws tus kheej: raws li cov thermocouple tsis tas yuav them cov khoom siv hluav taws xob, nws tsis yooj yim rau spontaneous cua sov thiab nws tus kheej muaj kev nyab xeeb.
Qhov tsis zoo ntawm kev siv thermocouple:
1. Complex signal conditioning: converting thermocouple voltage rau hauv usable kub nyeem ntawv yuav tsum tau ntau lub teeb liab txias. Cov teeb liab txias ib txwm siv ntau lub sijhawm tsim, kev ua haujlwm tsis raug yuav qhia txog kev ua yuam kev, ua rau txo qhov raug.
2. Tsis tshua muaj tseeb: ntxiv rau qhov tsis raug ntawm cov thermocouple sab hauv vim yog cov yam ntxwv ntawm cov hlau, qhov ntsuas qhov tseeb ntawm thermocouple tsuas tuaj yeem ncav cuag qhov ntsuas qhov tseeb ntawm qhov ntsuas qhov ntsuas qhov ntsuas kub, feem ntau hauv 1 ° C txog 2 ° C.
3. Qhov tsis zoo rau corrosion: raws li cov thermocouple yog tsim los ntawm ob yam hlau sib txawv, hauv qee qhov kev ua haujlwm, corrosion kuj tuaj yeem txo qhov raug raws sijhawm. Yog li ntawd, thermocouple xav tau kev tiv thaiv thiab kev saib xyuas ib txwm yog qhov tseem ceeb.
4. Cov suab nrov tsis zoo: thaum ntsuas lub teeb liab hloov ntawm qib zeb volt, suab nrov tsim los ntawm cov hluav taws xob tsis zoo thiab cov hlau nplaum yuav ua rau muaj teeb meem. Stranded thermocouple hlau khub tuaj yeem txo cov hlau nplaum sib txuas. Kev sib txuas hluav taws xob tuaj yeem raug txo los ntawm kev siv cov cables thaiv los yog los ntawm kev thaiv thiab thaiv hauv cov hlau txuas.
