Txoj kev txiav txim siab nquag thiab passive thermocouples

1. Lub hauv paus ntsiab lus ntawm thermocouples
Lub thermocouple yog ib qho sensor uas siv cov nyhuv thermoelectric los ntsuas qhov kub thiab txias. Lub thermocouple yog tsim los ntawm kev sib txuas ntawm ob lub hlau sib txawv. Thaum cov hauj lwm ntawm ob qhov kev sib cuag nyob ntawm qhov sib txawv ntawm qhov kub thiab txias, qhov sib txawv ntawm qhov kub thiab txias yog tsim, uas ua rau muaj peev xwm ua kom muaj cua sov. Los ntawm kev ntsuas qhov loj ntawm qhov thermoelectric peev xwm, qhov ntsuas kub tuaj yeem txiav txim siab.
2. Qhov sib txawv ntawm cov active thermocouples thiab passive thermocouples
Qhov sib txawv ntawm cov khoom siv thermocouples thiab passive thermocouples nyob rau hauv seb puas yuav tsum tau siv hluav taws xob sab nraud.
3. Cov txheej txheem rau kev txiav txim siab qhov nquag thiab tsis ua haujlwm ntawm cov thermocouples
Txoj hauv kev tseem ceeb los txiav txim siab qhov ua tau zoo thiab tsis muaj zog ntawm cov thermocouples yog saib xyuas txoj kev sib txuas ntawm cov pob qij txha thiab cov khoom siv.
Lub connector ntawm ib tug active thermocouple feem ntau yog ib lub qhov (socket) nrog ob qho tib si leads tam sim no, thiab ib tug plug-in lead tuaj yeem txuas lub thermocouple rau lub hwj chim mov. Cov thermocouples nquag tuaj yeem ua kom muaj peev xwm ua kom sov tsis tas yuav tsum muaj lub zog hluav taws xob sab nraud, yog li lawv tsuas yog yuav tsum tau muab tso rau hauv qhov ntsuas ntsuas thaum siv.
Kev sib koom ua ke ntawm passive thermocouple feem ntau yog cov hlau txuas txuas tsis muaj lub qhov (socket). Passive thermocouples xav tau cov khoom siv hluav taws xob sab nraud, yog li lawv cov hlau lead yuav tsum tau muab tso rau hauv cov khoom siv hluav taws xob sab nraud ua ntej txuas nrog cov ntsuas ntsuas rau kev ua haujlwm ib txwm muaj.
Los ntawm kev soj ntsuam txoj kev sib txuas ntawm cov thermocouple pob qij txha thiab cov hlau lead, peb tuaj yeem txiav txim siab seb lub thermocouple puas ua haujlwm lossis tsis ua haujlwm. Cov thermocouples nquag tsis tas yuav siv hluav taws xob sab nraud, thaum cov thermocouples passive yuav tsum tau txuas nrog lub zog sab nraud kom ua haujlwm zoo. Hauv kev siv tswv yim, xaiv hom thermocouple tsim nyog raws li xav tau.
