K-hom kub thermocouple kub thiab ntau thiab qhov tsis zoo?
Cov tshuaj hu ua "electrode" (KP) yog Ni: Cr = 90: 10, thiab cov ntaub ntawv pov thawj ntawm cov tshuaj tsis zoo (KN) yog Ni: Si = 97, thiab lub npe ntawm cov K-hom thermocouple cov khoom siv yog Ni,: 3, nws yog ib qhov kub siab ntsuas tau tus nqi siab tshaj ntawm cov thermocouple, muaj automation yog feem ntau siv los ua thermocouple. Raws li cov nickel-chromium-nickel-silicon alloy muaj ib tug zoo kub oxidation kuj, tuaj yeem siv rau oxidizing lossis nruab nrab nruab nrab. Li no K-hom thermocouple yuav ua kev ntsuas ntev txog 1000 degrees ntawm kev kub siab, lub sij hawm luv yuav raug ntsuas txog 1200 degrees. Txawm li cas los xij, nws yuav siv tsis tau rau hauv kev tawm xov xwm tawm, tsis li, qhov txhauv tsis ntev yuav tawg, qhov no tsuas yog siv rau kev ntsuas hauv qab 500 degrees. Nws yog qhov pheej yig tshaj li tus S-hom thermocouple, nws zoo repeatability, ua rau muaj cua sov thermal, thiab yog li siab rhiab, thiab nws cov linear zoo. Txawm hais tias nws ntsuas tseeb yog me ntsis qis, tab sis muaj peev xwm ua kom tau raws li qhov kub thiab txias, ces nws yog kev lag luam feem ntau siv thermocouple.
Hloov tau K-hom thermocouple muaj peb qhov zoo tshaj plaws:
1. Txoj kev thev ntawm lub thermoelectromotive quab yuam yog qhov zoo.
2.1000 ℃ qis dua qhov oxidation zoo.
3. Nyob rau hauv lub qhov txav hlau thermocouple stability yog qhov zoo.
K-hom thermocouple muaj plaub qhov kev tsis txaus siab nram no:
1. Tsis siv rau lub chaw ua pa, cua carbon monoxide, sulfur dioxide, hydrogen sulfide thiab lwm cov roj cua.
2. Thermoelectromotive quab yuam hloov nrog cov thawv muaj hlau zoo heev
Ntau tshaj.
3. Yuav raug cuam tshuam los ntawm cov kab thooj av yuav ua rau kom raug.
4. cuam tshuam los ntawm qhov tshwm sim rov pib dua.
