Taw qhia
Thermocouples yog ntsuas kub ntsuas cov cuab yeej ua haujlwm raws li Seebeck effect, uas hais tias kev sib tshuam ntawm ob yam khoom sib txawv ua rau lub teeb liab voltage raws li qhov kub ntawm qhov sib txawv ntawm ob qhov sib txuas. Cov cuab yeej no tau siv dav hauv ntau qhov chaw, suav nrog tshuaj lom neeg, petrochemical, thiab kev lag luam tsim hluav taws xob. Hauv kab lus no, peb yuav tham txog peb txoj cai ntawm thermocouples uas ib tus yuav tsum ua raws thaum siv lawv.
Thawj Txoj Cai ntawm Thermocoules - Homogeneous Reference Junction
Thawj txoj cai ntawm thermocouples hais tias qhov kub thiab txias ntawm qhov kev sib tshuam yuav tsum nyob tas li. Txhawm rau kom ntseeg tau tias qhov no, nws raug nquahu kom siv lub homogeneous kub siv qhov sib txuas. Qhov kev sib tshuam no yuav tsum nyob ntawm qhov kub ib yam li ib puag ncig uas ntsuas qhov ntsuas kub.
Qhov tseem ceeb ntawm Thawj Txoj Cai
Txoj cai lij choj no tseem ceeb heev vim tias qhov kev sib txuas lus tseem ceeb yog qhov tseem ceeb hauv kev txiav txim siab qhov kub thiab txias. Yog tias qhov sib txuas qhov kub tsis tas li, nws yuav qhia qhov ua yuam kev hauv qhov ntsuas kub. Lub homogeneous reference junction xyuas kom meej tias qhov sib txawv ntawm qhov kub thiab txias ntawm qhov ntsuas qhov sib txuas thiab qhov kev siv junction tseem nyob tas li, yog li muab qhov ntsuas qhov tseeb.
Txoj Cai Thib Ob ntawm Thermocouples - Txoj Cai ntawm Cov Hlau Nruab Nrab
Txoj cai thib ob ntawm thermocouples, tseem hu ua txoj cai lij choj ntawm cov hlau nruab nrab, hais tias lub zog hluav taws xob ntawm lub thermocouple yog qhov ua haujlwm ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm ob qhov sib txuas thiab ob lub hlau 'thermo-hluav taws xob lub zog sib txuas. Txoj cai no yog qhov tseem ceeb thaum siv cov thermocouple sib txawv thiab cov hlau sib txawv thaum ntsuas kub.
Qhov tseem ceeb ntawm Txoj Cai Thib Ob
Txoj cai lij choj ntawm cov hlau nruab nrab yog qhov tseem ceeb vim tias nws pab xaiv txoj cai ntawm thermocouple rau ib daim ntawv thov. Cov hlau sib txawv muaj lub zog hluav taws xob sib txawv, thiab qhov ntsuas kub ntawm ib daim ntawv thov txiav txim siab seb hom thermocouple thiab hlau sib xyaw yuav tsum siv li cas. Txoj cai thib ob muab lub moj khaum rau kev xaiv cov thermocouple uas tsim nyog thiab cov hlau sib txuas.
Txoj Cai Thib Peb ntawm Thermocouples - Txias Junction Compensation
Txoj cai thib peb ntawm thermocouples yog txoj cai ntawm kev sib tshuam txias. Nws hais tias qhov hluav taws xob ntawm lub thermocouple Circuit Court yuav tsum tau ntsuas ntawm qhov ntsuas qhov sib txuas qhov ntsuas kub kom them rau cov kev hloov pauv ntawm qhov ntsuas qhov ntsuas kub uas yuav tshwm sim thaum lub sijhawm ntsuas.
Qhov tseem ceeb ntawm Txoj Cai Thib Peb
Txoj cai thib peb ntawm thermocouples yog qhov tseem ceeb hauv kev ntsuas qhov ntsuas kub kom raug, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov ntsuas qhov ntsuas kub yuav txawv. Qhov ntsuas hluav taws xob ntsuas ntawm qhov kev sib tshuam yog nyob ntawm nws qhov kub thiab txias, thiab kev hloov pauv ntawm qhov kub thiab txias tuaj yeem cuam tshuam rau qhov ntsuas hluav taws xob. Kev siv cov nyiaj sib tshuam txias kom ntseeg tau tias txhua qhov kev hloov pauv hauv qhov kev siv qhov sib txuas qhov kub thiab txias tau them rau qhov ntsuas kub kom raug.
Xaus
Hauv cov ntsiab lus, peb txoj cai ntawm thermocouples yog qhov tseem ceeb hauv kev muab qhov ntsuas kub kom raug. Thawj txoj cai kom ntseeg tau tias qhov kub thiab txias ntawm qhov kev siv junction tseem nyob tas li. Txoj cai thib ob muab lub hauv paus rau kev xaiv cov thermocouple uas tsim nyog thiab cov hlau ua ke. Txoj cai thib peb them nyiaj rau cov kev hloov pauv hauv qhov kev sib tshuam qhov ntsuas kub kom muab qhov ntsuas kub kom raug. Los ntawm kev ua raws li cov cai no, peb tuaj yeem xyuas kom meej qhov ntsuas kub zoo siv cov thermocouples hauv ntau daim ntawv thov.
