Tsom xam ntawm txhua hom thermocouple

1. platinum Rhodium {}} platinum-{}} niobium alloy, ntawm chav sov, Nws lub peev xwm thermoeltric yog qhov me me, yog li feem ntau tsis tas yuav them cov xaim hluav taws xob thaum ntsuas qhov kub ntawm qhov kub txias thaum txias; Lub sijhawm ntev siv ntsuas kub yog 1600, luv-luv yog 1800, vim hais tias lub thermoelectric peev xwm me me, nws yuav tsum tau nruab cov twj paj nruag nrog siab dua siab dua {}}

2.} hom b thermouples yog tsim nyog rau kev siv hauv oxidizing lossis nruab nrab siv rau kev siv luv luv hauv lub tshuab nqus tsev; Txawm nyob hauv qhov chaw txo qis, lawv lub neej yog 10 txog 20 zaug ntawm R lossis S hom; Ua los ntawm platinum-rhodium alloy, tsis muaj qhov tsis xws li ntawm platinum thermocouple anode, muaj me ntsis crystallization ntawm qhov kub, thiab nws muaj lub zog loj; Nyob rau tib lub sijhawm vim nws nqus ntawm impurities lossis tsiv teb tsaws chaw muaj kev cuam tshuam loj, yog li tom qab lub sij hawm thermoelecricages kim heev (txheeb ze rau ib leeg platinum rhodium).

{{{{{{{{{{}}}} Txoj Kev Tsis Zoo-Thickoy (Nickel-Seem-silicon (Neekel-Thoj) Nickel) {{. nws tuaj yeem ntsuas qhov kub me me yog 1200}} Qhov kev sib raug zoo ntev yog 1200} Nws yog kwv yees linear thiab qhov nqi yog pheej yig. Thermocouple {{}} k-hom thermocochles yog wb siv rau hauv lub tshuab nqus tsev thiab cov pa roj carbon monoxide, cov pa roj carbon monoxide, cov pa roj carbon monoxide, Thaum cov pa Oxygen ib nrab yog tsawg, Nickel-chromium lub chromium yuav xum nyob rau hauv nws} yog li ntawd, ib tug hlau tiv thaiv raj yog siv {25}.

4.} Qhov tsis zoo ntawm K-hom thermocoecles: (1) Cov khoom siv kub siab tshaj li 1000), feem ntau), nws feem ntau puas ntsoog los ntawm oxidation; (2) Lub sijhawm luv luv thermal hluav taws xob ruaj khov nyob rau hauv thaj tsam ntawm {9} Tsis muaj qhov sib txawv thiab poob, thiab qhov sib txawv tuaj yeem ncav cuag 2 ~ 3; (3) Qhov tsis zoo electrode yog 150 ~ kev sib nqus hloov tshwm sim nyob rau hauv thaj tsam ntawm chav ntsuas ntawm chav ntsuas ntawm chav ntsuas kub rau 230, tshwj xeeb yog thaum siv kev cuam tshuam nrog kev cuam tshuam nrog cov kev cuam tshuam muaj peev xwm ntau yam tshwm sim; (4) Lub sijhawm ntev-los ntawm kev hloov chaw nruab nrab, vim muaj kev hloov pauv hluav taws xob tsis zoo, ua rau muaj kev hloov pauv loj hauv lub peev xwm.

{{05.} Npib Hluav Taws Xob-silicon-silicon Threatorce (Performance kub tsis kam thiab luv luv ntawm 400 rau 1300, tus Cov yam ntxwv thermoelectric ntawm n hom thermocouple yog linearly zoo dua li K hom; Txawm li cas los xij, cov nonlineear yuam kev hauv qhov kub tsawg (-200}}}}}}}) yog qhov loj, thiab nyuaj rau kev ua haujlwm.

6, Tooj liab-npib thickocouple (index t-thermocouple, nws muaj qhov tseeb tshaj plaws thiab kev sib luag zoo ntawm cov kub hluav taws xob; nws siv kub yog -200-350, vim tias tooj liab-{}}}}}}}}}}}} {} khoom .

7.} Iron-thermocouple (index. Qhov ntsuas kub li niaj hnub no tsuas yog 500 lossis tsawg dua, vim tias tom qab qhov kub thiab txias ntawm cov kab hlau kub yog siv tau ntawm qhov kub thiab txias {9} Nws muaj lub neej ntev; Lub thermocouple yog resistant rau hydrogen (H2) thiab siv roj carbon monoxide (CO) roj (piv txwv li 500)

{{08. nickel-chromium-tooj-nickel loj tshaj plaws, uas yog, qhov rhiab siab yog qhov siab tshaj plaws; Nws daim ntawv thov ntau yog tsis dav raws li qhov K-hom, tab sis nyob rau hauv cov kev mob siab, qis {9} nws feem ntau xaiv; Cov kev txwv hauv kev siv yog tib yam li cov hom K, tab sis tsis rhiab heev rau corrosion nrog lub siab noo noo {}}

Ntxiv nrog rau cov saum toj no yim feem ntau siv thermocouples, platinum-molybardum thermocoidlass .
