Monga tonse tikudziwa, ntchito yaikulu ya thermocouples ndi kuyeza ndi kulamulira kutentha. Amagwiritsidwa ntchito kwambiri m'mafakitale monga petrochemical, pharmaceutical and kupanga. M'mafakitale, kuwunika kolondola kwa kutentha kumagwirizana kwambiri ndi kuwongolera kwamtundu wazinthu komanso kukonza bwino kwazinthu. Chifukwa chake, waya wa platinamu-rhodium thermocouple ndi chisankho chodalirika komanso cholondola pakati pamitundu yambiri yazogulitsa.
Koma ndi chiyaniplatinamu-rhodium thermocouple waya? Mwachiwonekere, ndi thermocouple yopangidwa ndi zitsulo ziwiri zamtengo wapatali, platinamu ndi rhodium, zomwe zimapangidwa mwapadera kuti zipirire kutentha kwambiri komanso kupereka kutentha kolondola pansi pamikhalidwe yovuta kwambiri. Zitsulo zonsezi zimasankhidwa mosamala chifukwa cha malo osungunuka kwambiri, kukana kwa dzimbiri komanso kutentha kwakukulu. Mitundu yodziwika bwino ya waya wa platinamu-rhodium thermocouple timawona ndi S-mtundu (platinamu-10% rhodium / platinamu) ndi R-mtundu (platinamu-13% rhodium / platinamu) thermocouples.
Waya wa platinamu-rhodium thermocouple uli ndi zinthu zingapo zofunika. Choyamba, waya wa platinamu-rhodium thermocouple amatha kupirira kutentha mpaka 1600 ° C (2912 ° F), ndikupangitsa kuti ikhale yoyenera ntchito zotentha kwambiri monga kukonza kutentha, kuyang'anira ng'anjo ndi kupanga ndege. Kachiwiri, kuphatikiza kwa platinamu ndi rhodium mu waya wa thermocouple kumatsimikizira kukhazikika komanso kubwereza kwa kuyeza kwa kutentha, ngakhale pakugwira ntchito movutikira. Kuphatikiza apo, waya wa platinamu-rhodium thermocouple alinso ndi kukana kwamphamvu kwa dzimbiri, komanso nthawi yoyankha mwachangu, ndipo wayayo amatha kuyeza kutentha kwachangu komanso kolondola, komwe kumakhala kofunikira kwambiri pamakina opanga mafakitale.
Waya wa platinamu-rhodium thermocouple amagwiritsidwa ntchito kwambiri m'mafakitale omwe ali ndi zofunika kwambiri pakuyeza ndi kuwongolera kutentha kwambiri. Mwachitsanzo, m'makampani opangira kutentha, waya wa platinamu-rhodium thermocouple amagwiritsidwa ntchito poyang'anira ndikuwongolera kutentha kwa ng'anjo, mavuni ndi njira zochizira kutentha kuti zitsimikizire kuti zinthu zofunikira zimakwaniritsidwa. Kuphatikiza apo, makampani opanga zakuthambo amadalira waya wa platinamu-rhodium kuti awonetsere kutentha kwanthawi yayitali panthawi yopanga zida za ndege, zida za injini ndi zida zina zazikulu zakuthambo. Makampani opanga magalasi ndi ceramic amawagwiritsa ntchito kuyang'anira kutentha kwa ng'anjo ndi ng'anjo zomwe zimagwiritsidwa ntchito popanga magalasi, zoumba ndi zowuma.
Mwachidule,platinamu-rhodium thermocouple wayandi chida chofunikira choyezera kutentha ndi kuwongolera m'munda wamakampani omwe amatentha kwambiri. Kuchita kwake bwino kwambiri, kutentha kwakukulu ndi kudalirika kumapangitsa kukhala chisankho choyamba kwa mafakitale omwe ali ndi zofunikira kwambiri kuti zikhale zolondola komanso zokhazikika. Kaya mumagwira nawo ntchito zochizira kutentha, kupanga ndege, kukonza petrochemical, kapena mafakitale ena omwe amafunikira kuyeza kutentha kwambiri, waya wa platinamu-rhodium thermocouple amapereka kulondola komanso kulimba komwe kumafunikira kuwonetsetsa kuti ntchitoyo ikuyenda bwino komanso kuti zinthu zili bwino.
