Dab tsi ntawm cov kev tiv thaiv kub ntawm kub tiv thaiv cov platinum Rhodium throdoco thermoco thermocouples tuaj yeem faib raws li lawv cov pes tsawg leeg?

Tus shortcomings ntawm high-resistant platinum Rhodium thermoco thermocoical, thiab yog li ntawd kev nqis peev ntau-sij hawm. S-hom thermocouple, tseem hu ua ib leeg platinum rhodium thermocouple, muaj steriven cim qhov kub ntawm nruab nrab ntawm {}} thiab 1600 degree. Nws yog qeb ntawm cov khoom siv hlau ua hluav taws xob. Kev siv ib txwm muaj nyob rau hauv qhov chaw kub-ib puag ncig xws li coking nroj tsuag thiab hlau mills.

Kev kub siab tiv taus platinum rhodium throdoco thermocoalces muaj qhov tseeb, ruaj khov, thiab lub neej ntev nyob rau hauv lub thermocouple koob Nws muaj cov khoom siv lub cev zoo thiab tshuaj lom neeg, khov kho thermoelectric muaj peev xwm, thiab oxidation thermoelectric tsis kam ntawm cov kub, ua rau nws cov oxidizing thiab inert atmospheres. Vim nws tau ua tau zoo heev, S-hom siab tiv thaiv thermocouple, tau ntev tau siv los ua kev cuam tshuam ntsuas rau qhov ntsuas kub rau qhov kub. Txawm hais tias "nws {-90" cov rooj sib tham uas nws yuav tseem siv rau qhov ntsuas kub sab hauv tseem ceeb tuaj yeem siv rau kev ntsuas kub.

Cov khoom siv ntawm cov raj tiv thaiv raj rau qhov kub - tiv taus platinum rhodium throdocouple:

Cov ntaub ntawv feem ntau siv raws li kev tiv thaiv cov hlab rau platinum rhodium throdocoucles, thiab kub-tiv taus alloy cov ntaub ntawv.

1. Cov leeg roj nplua yog siv los ua cov leeg tiv thaiv rau S-Typ mob thermocoples thiab r-ntaus thermocouples. Lawv feem ntau yog siv nyob rau ntawm qhov kub tsawg dua lossis sib npaug nrog 1300 degree, tab sis lawv qhov ntom ntom thiab kub tsis kam yog qis dua rau cov ntawm corundum tubes.

2. Cov hlab ntaws siab yog siv raws li kev tiv thaiv cov raj rau b-hom thermorochles, thiab tseem siv tau raws li kev tiv thaiv cov hlab thiab R-ntaus thermocouples. Lub sijhawm ntev siv ntsuas kub ntawm Corundum Tube yog 1600 degree, lub tsheb soceve siv qhov point yog 1900 degree, thiab qhov ntsuas kub siab tshaj plaws yog 1950 degree. Cov neeg siv yuav tsum xaiv 99 corundum tub nrog lub siab hluav taws xob kub thiab ntom ntom thaum xaiv corundum tub.
Kev kub siab tiv taus Platinum Rhodium thermoco thermoco thermoco thermocofles tsis txhob muab cais raws cov hauv qab no raws li lawv cov kev sib xyaw:

1. Platinum rhodium 30 Platinum Rhodium 6 Thermocouple: nrog kev faib tus lej b, tseem hu ua dual platinum rhodium rhodium thermocouple; Lub sij hawm ntsuas ntev ntawm 1600 DEGUREME KUB NTXIV, ntsuas qhov luv ntawm 1800 decurity Kub; B-hom thermoroup yog cais rau hauv chav kawm qib 2 thiab Chav Kawm III raws li kev siv cov kev siv thiab cov yam ntxwv thermoelrictric.

2. Platinum Rhodium 10 Platinum Thermocouple: Division Mots S; Nws tuaj yeem ntsuas ntsuas kub ntawm 1300 degree rau lub sijhawm ntev thiab 1600 degree rau lub sijhawm luv luv. Lub raj tiv thaiv tiv thaiv feem ntau yog ua los ntawm cov raj loj los yog corundum raj lossis corundum raj; S-hom thermoounles tau muab cais rau hauv chav kawm I thiab chav kawm II raws li kev siv cov kev siv thiab thermoelricric cov yam ntxwv.

3. Platinum Rhodium 13 Platinum Thermocouple: Division tus lej R; Nws tuaj yeem ntsuas ntsuas kub ntawm 1300 degree rau lub sijhawm ntev thiab 1600 degree rau lub sijhawm luv luv. Lub raj tiv thaiv tiv thaiv feem ntau yog ua los ntawm cov raj loj los yog corundum raj lossis corundum raj; R-ntaus thermorouples yog cais rau hauv chav kawm I thiab chav kawm II raws li kev siv cov kev siv thiab cov yam ntxwv thermoelrictric.
