Muaj pes tsawg hom thermocouple?
Ces peb thiaj li to taub ntau npaum li cas feem ntau siv thermocouple degree?
Thermocouple nyob rau hauv cov khoom yog ib qho kev ntsuas kub tsis txaus, tab sis ntau hom thermocouple, hom thermocouple thiab sub-degree tus naj npawb rau cov neeg siv feem ntau.
1, thermocouple indexing tus naj npawb yog tsuas yog S, R, B, N, K, E, J, T, PEB thiab lwm yam. Nws yog S, R, B yog lub thawv kub thermocouple, N, K, E, J, T yog pheej yig hlau thermocouple, S sub-degree yog characterized los ntawm muaj zog antioxidant kev ua tau zoo, yuav tsum tau oxidized, inert cua rau nruam siv, ntev -term Siv cov ntsuas kub 1400 ℃, luv luv 1600 ℃. Hauv tag nrho cov thermocouples, S scale muaj theem siab tshaj ntawm cov neeg thiab feem ntau yog siv los ua tus txheej txheem thermocouple;
2, R cov cim qhab nia thiab S sub-degree piv rau thermal electromotive quab yuam txog li 15%, lwm cov kev ua haujlwm yuav luag zoo li qub;
3, B sub-degree ntawm chav sov thermoelectromotive quab yuam yog heev me me, yog li qhov ntsuas feem ntau tsis them nyiaj xaim. Nws lub sij hawm ntev kub yog 1600 ℃, ntus 1800 ℃. Yuav siv tau rau hauv oxidizing lossis nruab nrab qhov nruab nrab, tab sis kuj siv nyob rau hauv kev siv lub sijhawm luv luv hauv lub tshuab nqus tsev.
4, N sub-degree yog characterized los ntawm kev kub siab oxidation ntawm 1300 ℃, stability ntev ntawm thermoelectromotive quab yuam thiab thermal thermal voj voog ntawm zoo reproducibility, tsis kam mus rau nuclear tawg thiab tsis muaj kev kub Performance Ye Hao, koj tau ib nrab hloov S ntsiab lus Degree thermocouple;
5, K sub-degree yog characterized los ntawm muaj zog antioxidant, yuav tsum nyob rau hauv oxidising, inert cua rau kev siv nruam, siv ntev lub sij hawm kub ntawm 1000 ℃, ntev 1200 ℃. Qhov feem ntau dav siv nyob rau hauv tag nrho cov thermocouples;
6, E sub-degree yog tsi ntsees los ntawm feem ntau siv thermocouple, qhov siab tshaj plaws thermoelectromotive quab yuam, uas yog, lub siab tshaj plaws. Yuav tsum tau siv nyob rau hauv oxidizing, inert cua, kev siv kub ntawm 0-800 ℃;
7, J sub-degree yog qhia los ntawm ob qho tib si rau qhov chaw oxidizing (kev siv ntawm qhov kub nruab nrab ntawm 750 ℃), tuaj yeem siv los txo cov cua (siv qhov siab kub ntawm 950 ℃), thiab tsis kam ua rau H2 thiab CO pa roj carbon dioxide, thiab ntau dua rau txhim kho thiab tshuaj;
8, T sub-degree yog tsi ntsees los ntawm tag nrho cov pheej yig hlau thermocouple hauv siab tshaj plaws ntawm cov neeg, feem ntau yog siv los ntsuas qhov ntsuas kub hauv qab no 300 ℃
Nyob rau hauv dav dav, cov no yog cov suav lag luam, muaj xws li: tungsten rhenium thermocouple, R qauv thermocouple yuav tsum muaj ntau yam li 13 hom.
