Platinum-Rhodium thermoco thermocouples: precision nyob rau hauv high-igh ntsuas

Nyob rau hauv lub sau ntawm kev ntsuas siab siab, platinum - Rhodium thermoco thermocoumles tau raug lees paub tias yog kev daws teeb meem thiab meej. Lawv cov khoom sib xyaw ua ke thiab cov khoom ua rau lawv sawv hauv cov ntawv thov uas yog cov ntaub ntawv ntsuas kub yog qhov tseem ceeb.

Platinum - Rhodium thermoco thermocouples yog ua los ntawm kev sib txuas platinum, ib qho ruaj khov thiab muaj kuab, uas ua rau nws cov kev ua tau zoo nyob rau hauv huab. Qhov no alloy - raws cov qauv tsim kho lub hauv paus ntawm lawv lub peev xwm zoo kawg.

Ib qho ntawm cov muaj txiaj ntsig zoo tshaj plaws ntawm Platinum - Rhodium thermoco thermocouples yog lawv qhov kev kub siab - kub. Lawv tuaj yeem ua haujlwm tau zoo nyob rau hauv qhov kub tau nce mus txog 1768 degree, ua rau lawv haum rau ntau cov txheej txheem kev muaj kub - cov txheej txheem kub. Hauv cov iav tsim tawm, piv txwv, melting ntawm cov khoom siv raw yuav tsum muaj kub heev. Platinum - Rhodium thermocouples tuaj yeem tso rau hauv lub khob molten lossis muab tso rau ze rau cov cua sov phab ntsa kom ntsuas qhov kub. Qhov no ua kom pom tseeb tias lub khob muaj txoj cai viscosity thiab kev ua tau zoo thaum kev tsim khoom, raws li tseem me me kub hloov tuaj yeem cuam tshuam cov khoom kawg.

Qhov tseeb yog lub zog tseem ceeb ntawm cov thermocouples. Lub ruaj khov thermoelectric thaj chaw ntawm lub platinum cov platinum - Rhodium alloy pab kom haum thiab kho dua tshiab ntawm cov cim hluav taws xob. Hauv kev tshawb fawb, tshwj xeeb tshaj yog nyob rau hauv kev sim siab - kev sim siab, ntsuas qhov ntsuas kub yog qhov tseem ceeb. Seb nws kawm cov cwj pwm tshiab ntawm huab cua txias tshiab lossis ua cov tshuaj siab - cov tshuaj txhuam dej kom muaj qhov tseeb uas xav tau rau cov txiaj ntsig kom ntseeg tau.

Tshuaj lom zem ruaj khov yog lwm qhov kom zoo dua. Nyob rau hauv kev loj - ib puag ncig kub, muaj feem ntau corrosive gases thiab lwm yam kuab lom tam sim no. Lub Platinum - Rhodium Alloy yog cov nquag tiv thaiv corrosion, tso cai rau cov kev ncaj ncees thiab txuas ntxiv muab ntsuas qhov tseeb dua ncua sijhawm. Nyob rau hauv ib tug hlau smelting rauv, qhov twg cov sulfur dioxide thiab lwm cov roj acidic ua rau platinum - Rhodium thermoco thermoouples kom ntseeg tau tias lawv tsis yooj yim.

Lub durability ntawm platinum - Rhodium thermoco thermocouples kuj tseem tsim nyog sau cia. Lawv tsim los tiv thaiv kev ua kom nruj ntawm cov ntawv thov kub siab - nrog rau kev caij tsheb kauj vab thizling, deeg, thiab kev ntxhov siab. Nyob rau hauv ib nruam casting kev ua haujlwm hauv kev lag luam steel, lub thermocouple yog nthuav tawm cov cua sov thiab txias kom zoo li vibrations los ntawm cov tshuab hnyav. Platinum - Rhodium thermocouples tuaj yeem tiv cov xwm txheej no, txo qhov xav tau ntawm cov txheej txheem hloov chaw thiab ua kom tiav txoj kev lag luam.

Txawm li cas los xij, platinum - Rhodium thermoco thermocouples muaj qee qhov kev txwv. Lawv yog tus nqi kim kim vim kev siv cov khoom siv hlau uas muaj txiaj ntsig zoo li Platinum thiab rhodium. Ib qho ntxiv, lawv qhov tseeb tuaj yeem cuam tshuam los ntawm kev kis tau los ntawm kev kis tau los ntawm kev sib kis tau, xws li cov txhuas lossis silicon, dhau sijhawm. Tab sis kom tsim nyog siv, ntsuas hluav taws xob, thiab kev txij nkawm tsim nyog, cov kev txwv no tuaj yeem tswj tau zoo.
