Raws li peb qhov kev tsom mus rau yav dhau los kub kub txhaj tshuaj molding scenarios, kev kho qhov sib sib zog nqus thermocouple tsuas yog siv tau raws li cov xwm txheej tshwj xeeb uas cov xov hlau thermocouple tsis muaj hnub nyoog hnyav thiab yuav tsum muaj cov txheej txheem kev tshaj lij. Qhov kev vam meej ntawm qhov sib sib zog nqus thermocouple kho nws txawv heev nyob ntawm seb hom kev ua txhaum:
Ib feem ntawm cov hlau tawg: Siv cov roj inert tiv thaiv vuam, qhov kev vam meej tuaj yeem ncav cuag 85% ~ 95%, ua rau nws qhov kev kho kom zoo tshaj plaws tam sim no.
Me ntsis oxidation drift: Kev ua tau zoo tuaj yeem raug kho los ntawm cov txheej txheem annealing thiab rov tsim dua tshiab, nrog kev ua tiav ntawm kwv yees li 60% ~ 75%. Qee cov xov hlau thermocouple uas muaj hnub nyoog hnyav hauv cov nplej tsis tuaj yeem muaj lawv cov kev ua tau zoo.
Loj - cheeb tsam sheath puas: Qhov kev ua tau zoo ntawm kev rov ua dua thiab kho tsuas yog 40% ~ 55%, thiab nws muaj feem cuam tshuam rau cov teeb meem xws li tsis zoo sealing thiab rwb thaiv tsev tsis ua haujlwm.
Yog hais tias lub ferrule muaj hnub nyoog hnyav thiab nkig, qhov ua tiav ntawm kev kho qhov tob yog tsawg dua 20%. Nyob rau hauv cov xwm txheej zoo li no, hloov nws nrog ib feem tshiab muaj kev nyab xeeb dua li kev kho nws.
