Dab tsi yog qhov txawv ntawm S-hom thiab T-hom thermocouples

Qhov sib txawv tseem ceeb ntawm S-hom thiab T- hom thermocouples nyob rau hauv lawv cov khoom muaj pes tsawg leeg, qhov kub thiab txias, cov yam ntxwv raug, qhov chaw tus nqi, thiab ib puag ncig siv tau. Lawv sawv cev rau ob txoj hauv kev hauv kev ua haujlwm siab - ntsuas qhov kub thiab txias: "precision high-precision precious hlau hom" thiab "tsawg- kub siab siab hom hlau hom." S-hom thermocouples yog haum rau siab- ntsuas qhov ntsuas kub siab tshaj 1300℃thiab tau dav siv hauv metallurgy, iav tsim, thiab kev tshawb fawb kev sim uas yuav tsum muaj kev ruaj ntseg siab heev. T- hom thermocouples, ntawm qhov tod tes, tshwj xeeb hauv qis- ntsuas qhov ntsuas kub ntawm -200℃mus rau 350 degree, thiab muaj qhov zoo dua tsis tuaj yeem hloov pauv hauv cov ntawv thov uas xav tau siab thiab ruaj khov, xws li cov tub yees, kev sim tshuaj lom neeg, thiab kev tswj cua txias.

 

I. Cov Khoom Siv Khoom Siv: Hlau Hlau Platinum-Rhodium vs. Base Hlau Copper-Constantan

S-hom thermocouple (Platinum-Rhodium 10-Platinum): Cov electrode zoo yog platinum-rhodium alloy (SP) muaj 10% rhodium, thiab cov electrode tsis zoo yog platinum ntshiab (SN). Nws belongs rau qeb ntawm precious hlau thermocouples.

Vim yog siv cov hlau tsis tshua muaj platinum thiab rhodium, lawv kim heev, tab sis muaj qhov zoo heev -kub oxidation tsis kam thiab tshuaj lom neeg ruaj khov, nrog tsawg tsawg - lub sij hawm drift.

Hom T thermocouple (tooj liab-constantan): Qhov zoo electrode yog tooj liab ntshiab (TP), thiab cov electrode tsis zoo yog tooj liab -nickel alloy (constantan, TN). Nws belongs rau lub hauv paus hlau thermocouple qeb.

Nws muaj cov khoom siv qis, pheej yig, thiab rov ua dua tau yooj yim, ua rau nws tsim nyog rau kev siv loj - nplai.

Xaus: Hom S thermocouples yog tsim rau siab - peev nyiaj, siab - daim ntawv thov ntsuas qhov kub thiab txias; Hom T thermocouples yog qhov tsim nyog rau tus nqi - cov neeg siv khoom xav tau siab dua - cov lus teb qhov tseeb ntawm qhov kub qis.

 

II. Qhov kub thiab txias: Hom S thermocouples yog tsim los rau qhov kub thiab txias ntau yam, thaum Hom T thermocouples tsom rau qhov qis - qhov kub thiab txias.

Rooj: Hom	Ntev -lub sijhawm ua haujlwm kub	Luv -lub sijhawm ua haujlwm kub	Kev ntsuas tau zoo
Hom S	1300 degree	1600 degree	0 ~ 1600 degree
Hom T	350 degree	400 degree	-200 ~ +350 degree

Hom S thermocouples muaj qhov ntsuas kub siab dua thiab tsim nyog rau qhov kub siab tshaj - cov txheej txheem kub xws li molten steel kub ntsuas, iav rauv, thiab siab - kub sintering.

Hom T thermocouples npog ntau qhov kub thiab txias los ntawm cryogenic mus rau ambient, ua rau lawv tshwj xeeb tshaj yog haum rau qis - ntsuas kub ntawm -200℃txog 0℃. Nyob rau hauv qhov ntsuas kub no, lawv qhov kev ruaj ntseg txhua xyoo yog tsawg dua ± 3μV, ua rau lawv tsim nyog rau kev siv cov khoom siv thib ob rau kev hloov pauv tus nqi.

Lus Cim: Hom S thermocouples muaj qhov ntsuas kub tsis tshua muaj peev xwm thiab rhiab heev nyob rau hauv qhov qis - qhov kub thiab txias thiab tsis pom zoo siv rau hauv cov tshuab tub yees. Hom T thermocouples tsis tuaj yeem siv nyob rau hauv siab - qhov kub thiab txias oxidizing ib puag ncig; tooj liab cathode yog nquag oxidation thiab tsis ua hauj lwm saum 350 degree.

 

III. Kev sib piv ntawm qhov tseeb thiab cov khoom siv hluav taws xob tso tawm cov yam ntxwv

Hom S thermocouples: Ntawm cov thermocouples, lawv muab qhov tseeb tshaj plaws, kev ruaj ntseg zoo tshaj plaws, thiab kev rov ua dua tshiab. Lawv tau ntev siv los ua cov cuab yeej cuam tshuam rau International Temperature Scale ITS-90.

Txawm li cas los xij, lawv muaj qhov ntsuas kub tsis tshua muaj peev xwm (kwv yees li 6.3μV / degree) thiab qis rhiab heev, yuav tsum muaj siab -cov cuab yeej ua kom tau txais cov cim tsis muaj zog.

Hom T thermocouples: Lawv pom qhov zoo tshaj plaws linearity thiab stability nyob rau hauv -200 ~ 0℃ntau yam, nrog ib tug kuj siab thermoelectric peev xwm (kwv yees li 43μV / degree), siab rhiab heev, thiab muaj zog reproducibility. Nrog rau cov teeb liab tso tawm muaj zog thiab muaj zog tiv thaiv - muaj peev xwm cuam tshuam, nws feem ntau yog siv hauv cov tshuab ntsuas kub qis thiab cov qauv thermopile.

Piv txwv piv txwv: Ntawm 800℃, S- hom outputs kwv yees li 6.7mV, thaum T- hom tsis tuaj yeem tiv taus qhov kub no; ntawm -100℃, T- hom outputs kwv yees li -4.6mV, thaum S-hom tsuas outputs kwv yees li -0.5mV. T-hom teeb liab lub zog yog ze li ntawm 10 npaug zog, ua rau nws tsim nyog rau kev kuaj xyuas qhov sib txawv ntawm feeb.

 

IV. Environmental Adaptability thiab kev txwv kev siv

Rooj Environmental Type	S-type Performance	T-type Performance
Oxidizing Atmosphere	Zoo heev, ntev - ruaj khov	Tooj liab cathode yog yooj yim oxidized, tsis haum rau ntev - siv
Txo Huab Cua	Yooj yim paug, cuam tshuam kev ruaj ntseg	Siv tau, tiv taus H₂ thiab CO gas corrosion
Inert/Vacuum Ib puag ncig	Kev ua haujlwm ruaj khov	Siv tau, kev ua haujlwm zoo
Humidity Ib puag ncig	Tsis muaj qhov tshwj xeeb zoo	Corrosion resistant, haum rau huab cua puag ncig
Nqi thiab Kev Kho	Siab, loj pib peev	Tsawg, kho yooj yim, tus nqi siab -effectiveness

Kev pom zoo: S- hom yog siv rau hauv qhov chaw huv, siab- qhov kub thiab txias (xws li metallurgical furnaces, iav kilns); T- hom yog haum rau qis- qhov chaw muaj qhov kub thiab txias xws li cia txias, bioreactors, thiab cua txias tshuab.

 

V. Tej yam tshwm sim ntawm daim ntawv thov

S-hom thermocouple: Siv dav hauv steel smelting, iav melting rauv, ceramic sintering, aerospace cav saib xyuas, kev tshawb fawb tshawb fawb- qib siab- cov khoom siv ntsuas kub, thiab lwm lub sijhawm uas yuav tsum tau ntsuas qhov ntsuas kub siab heev.

Vim nws txoj kev ruaj ntseg zoo, nws kuj tau siv dav hauv cov qauv ntsuas rau kev lag luam thermocouples.

T-hom thermocouples: Feem ntau siv hauv qhov chaw txias txias, kev thauj mus los ntawm cov saw txias, cov chaw tsim tshuaj lom neeg, cov tshuab cua txias, cov tshuab cua txias, cov chav ntsuas cua sov, thiab lwm yam uas yuav tsum tau tswj qhov kub thiab txias.

Vim nws cov lus teb ceev ceev thiab raug siab, nws yog ib qho ntawm feem ntau siv cov txheej txheem thermocouples hauv cryogenic ntsuas kub.
