Kev ntsuas kub ntawm kev ntsuas kub ntawm thermocouple

Thermocouple yog qhov ntsuas kub thiab txias {}} Lub peev xwm sib txawv, thiab muaj qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv ntawm ob qho tib si yuav tsim nyob hauv lub voj, tsim kom muaj peev xwm ua kom lub zog txias dua, qhov ntsuas kub tam sim no tuaj yeem hloov kho lub zog cua sov .
Kev ntsuas kev ua haujlwm zoo ntawm thermocouples: thermocows muaj qhov ntsuas kub ntau thiab qhov ua tau ruaj khov; Kev ntsuas siab ntsuas qhov tseeb, cov thermocouple yog nyob rau hauv kev sib chwv nrog ntsuas ntsuas thiab tsis cuam tshuam los ntawm cov nruab nrab hauv nruab nrab; Ceev FOOD THEM TEB SIJHUB teb, cov thermocouple yog hloov kho kom sov hloov; Kev ntsuas ntau ntau, cov thermocouple yuav tsis txuas ntxiv ntsuas kub ntawm {}} {{1} degree; Lub thermocouple muaj kev txhim khu kev qha thiab kev ua haujlwm zoo zog. kev pabcuam ntev {}}

Lub thermocouple yuav tsum muaj ntawm ob tug neeg xyuas (lossis semiconductor) tab sis ntsib qee qhov kev xav tau los ua ib qho kev ntsuas kom kub thiab txias thiab txias rau qhov ntsuas kub thiab txias thiab txias

Weld ob tug neeg coj lossis semiconductors a thiab b ntawm cov ntsiab lus sib txawv yog tsim nyob rau hauv lub voj {} Qhov tshwm sim hauv lub voj voog Thermocouples ua haujlwm los ntawm kev siv cov nyhuv no .

Peb Txoj Cai ntawm Thermoco

1. Txoj cai ntawm homogeneous tus cwj pwm
Thaum ob qho kawg ntawm tib cov khoom siv homogeneous (tus neeg kos npe lossis ib qho kev sib tham tau muab tso tawm, tsis muaj qhov sib luag ntawm lub voj voos
Nws tuaj yeem pom tau tias thermouples yuav tsum muaj ntawm ob hom kev sib txawv, ntxiv {{} Yog cov khoom siv thermocofric tsis muaj qhov kub thiab txias .
2.} theem nrab kev coj ua
Thaum twg nruab nrab tus neeg xyuas?
Daim Ntawv Thov: Raws Li Cov Kev Siv Ntsuas Nruab Nrab, hauv qhov ntsuas kub tiag tiag yog muab qhib rau cov khoom siv ntsuas kub los ntawm kev ntsuas kub thiab txias .
Qee tus neeg muaj kev txhawj xeeb tias kev sib cuag tau tsim los ntawm cov xaim thiab cov xaim tooj liab tau txuas rau qhov ntsuas tooj liab uas yuav ua rau txoj cai no, tsis muaj qhov yuam kev zoo li no!
3. Txoj Cai Kub Nruab Nrab
Lub thermoelectric muaj peev xwm ntawm ob lub junctions
Daim Ntawv Thov: Txij li qhov thermocouple thiab feem ntau muaj kev sib raug zoo tsis muaj qhov tseeb tsis tuaj yeem siv ncaj qha saib lub rooj kom tau txais qhov kub kub kawg; nor can the actual thermoelectric potential E (t, t0) of the known circuit be used to directly look up the temperature value obtained by the table, and then add the cold end temperature to determine the measured temperature value of the hot end. Correction must be made according to the intermediate temperature law. Beginners often do not make corrections according to the intermediate temperature law!
