Yuav ua li cas xaiv armocouple lossis sib sau ua ke thermocouple

Kev sib piv ntawm cov thermored thermocouples thiab prefabricated thermocouples
1. Txog 400 degree
Kub Sensors tau siv los tshawb xyuas qhov kub thiab txias hauv cov txheej txheem kev siv feem ntau siv thermocoonotres thiab tus ua mob. Thaum qhov ntsuas kub feem ntau qis dua 400 degree, ib qho kev siv cua nab yog xaiv; Thaum qhov ntsuas kub siab ntawm 400 degree, siv thermocouple. Dab tsi yog vim li cas rau qhov no? Platinum resistors muaj cov ntsuas kub ntau dua li thermouples, thiab yog qhov kev xaiv uas nyiam tshaj plaws rau kev ntsuas kub nyob hauv tsawg. Hauv cov txheej txheem ntau lawm ntawm cov platinum tsim nyog, kev ua haujlwm siab tshaj plaws ntawm cov khoom yog txiav txim siab los ntawm kev ua haujlwm ntawm PT100 Cheebtsam. 400 degree yog qhov tseem ceeb rau kev xaiv platinum resistors thiab thermoounces, xav ob qho tib si kub thiab lub neej ntev. Nws raug nquahu kom nyeem "kev xaiv cov platinum tiv thaiv los txhim kho lub neej zoo thiab kev pab cuam ntawm cov chaw no

2. Cov ntsiab cai ntawm thermocouple
Thermocouples siv ob qho kev ua kom sib txawv sib txuas ua ke. Vim tias qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias, ib lub peev xwm thermoelectric yog tsim nyob rau hauv Circuit Court, uas yog hu ua cov nyhuv thermoelectric nyhuv. Thermocouples siv lub ntsiab cai no los ntsuas qhov kub.

3. Cov qauv ntawm cov thermored thermocouples
Cov txheej txheem txheej txheem thermoco tau muab faib ua cov rooj sib txoos thiab hom kev ua rog tau siv dav siv tam sim no. Armored Thermocouple yog tus qauv compression tsim los ntawm kev sib txuas thiab ncab cov khoom siv thermocoup (feem ntau yog cov hmoov av magnesium), thiab hlau raj hlau; Prefabricated thermoco yog thermocouple nrog thermocouple xov rau tej ceramic hlaws dai thiab nruab rau hauv cov raj hlau hollow hlau.

4. Kev sib piv ntawm cov thermocoed thermocouples thiab prefabricated thermocotres
Piv nrog prefabricated thermocouples, muaj cuab yeej thermocous muaj cov yam ntxwv hauv qab no thiab yog li ntawd siv dav. Tam sim no, lawv tau hloov prefabricated thermocouples nyob rau ntau zaus.
Cov yam ntxwv tseem ceeb ntawm cov thermored thermocouples yog:
① Lub taub loj tuaj yeem ua kom me me (tsawg kawg ntawm {0. 25mm), yog li lub sijhawm thermal teb yog me me thiab cov tshuaj tiv thaiv ceev nrawm nrawm.
② muaj cov khoom siv zoo thiab tuaj yeem tiv taus lub zog loj thiab kev cuam tshuam.
③ muaj qhov kev ua tau zoo flucural, nrog rau kev khoov hluav taws xob ntawm {}} lub cheeb, haum rau cov khoom siv thiab cov xwm txheej nrog cov txheej txheem nyuaj.
④ Cov xov hlau thermocouple yog them nrog insulating cov khoom siv thiab hlau armor, uas ua rau nws tsis tshua muaj kev cuam tshuam los ntawm lub neej nruab nrab thiab yog li muaj kev pabcuam ntev dua.
Nws tuaj yeem siv los ua qhov kub ntxhov hauv kev tiv thaiv kev tiv thaiv thermocouple los yog ntsuas cua sov.
Ib yam li ntawd, cov thirmored tus cua sov kuj muaj cov yam ntxwv saum toj no, hloov cov cua sov ua ke hauv ntau qhov chaw.
