Lub ntsiab cai tseem ceeb thiab cov txheej txheem tsim ntawm thermocouple kub ntsuas

1. Cov txheej txheem yooj yim ntawm cov ntsuas cua sov ntawm thermocouple
Weld ob cov khoom sib txawv ntawm cov neeg coj ua lossis cov semiconductors A thiab B ua ke los ua ib qho kev kaw Circuit Court. Thaum muaj qhov sib txawv ntawm ob qho tib si txuas cov ntsiab lus 1 thiab 2 ntawm kev coj ua A thiab B, lub zog hluav taws xob tau tsim los ntawm lawv, uas ua rau muaj qee qhov ntau ntawm cov hluav taws xob. Qhov tshwm sim no hu ua thermoelectric nyhuv. Thermocouples ua haujlwm los ntawm kev siv cov nyhuv no.
2. Hom thiab cov qauv tsim ntawm thermocouples
(1) Hom ntawm thermoco
Feem ntau siv thermocouples feem ntau muab faib ua ob pawg: qauv thermocoorples thiab cov thermoco zog. Tus txheem thermocouple raug xa mus rau qhov thermocouple uas muaj lub teb chaws muaj peev xwm qhia txog kev sib raug zoo thiab kub, tso cai rau qhov yuam kev, thiab muaj cov qauv kev sib koom tes. Nws muaj cov khoom sib txuam tso tawm rau kev xaiv. Tsis yog qauv thermocoen tsis yog raws li dav siv lossis ntawm tib qho kev txiav txim ntawm qhov ntau li qauv thermoco, thiab feem ntau tsis muaj kev sib koom tes ntawm cov lus sib txuas lus. Lawv feem ntau yog siv rau kev ntsuas hauv qee lub sijhawm tshwj xeeb.
Txij li Lub Ib Hlis 1, 1988, txhua qhov thermocoter thiab cov cua sov hauv Suav teb tau tsim los raws li IEC cov qauv thermoco, thiab t tau raug xaiv raws li kev tsim qauv thermocouples hauv Suav teb.
(2) Txhawm rau kom ntseeg tau tias txoj kev ntseeg siab thiab ruaj khov ntawm thermocoumles, cov cai kom muaj rau lawv muaj raws li hauv qab no:
① vuam ntawm ob lub thermoelectric cov hluav taws xob uas ua rau cov thermocouple yuav tsum yog khov kho;
Yog ob lub thermoelectric cov hluav taws xob yuav tsum tau zoo insulated los ntawm ib leeg los tiv thaiv luv luv circuits;
③ Qhov kev sib txuas ntawm cov hlau roj teeb thiab qhov kawg ntawm lub thermocouple yuav tsum yooj yim thiab ntseeg tau;
④ Tes Tsho Tiv Thaiv yuav tsum ua kom muaj kev sib cais txaus ntawm lub thermoelectric electrode thiab kev phom sij.
3. Qhov ntsuas kub ntawm thermocouple txias kawg
Vim yog qhov tseeb tias cov ntaub ntawv ntawm thermocouples feem ntau kim (cov xov tooj tsis tshua muaj zog) Nws yuav tsum tau taw qhia tias kev them hluav taws xob ntawm Thermocouple electrode thiab txav qhov txias txias ntawm thermocouple mus rau lub ntsuas lub davhlau ya nyob hauv chav tswj hwm. Nws tsis tuaj yeem tshem tawm cov cawv ntawm qhov kub ntawm qhov txias ntawm qhov txias txias rau ntawm ntsuas kub thiab tsis muaj kev them nyiaj. Yog li ntawd, lwm txoj kev kho kho yuav tsum tau siv los them rau qhov cuam tshuam rau qhov cuam tshuam ntawm txias txias t} {}}} {}} 0 degree rau ntawm ntsuas kub.
Thaum siv Thermocule Them Nyiaj xaim, kev saib xyuas yuav tsum tau them rau cov qauv sib txuam, thiab qhov ntsuas kub ntawm qhov kev them nyiaj xaus ntawm cov xaim xaim thiab thermocouple tsis tau tshaj 100 degree.
