Ukukhusela ezi sensors ngokufanelekileyo kubalulekile ukuze kusebenze kakuhle. Iityhubhu zesafire, ezenziwe nge-synthetic single-crystal aluminum oxide, ziye zabonakala ziphakathi kwezinto ezithembekileyo zokukhusela okunjalo. Eli nqaku lihlola iimpawu ezizodwa zeetyhubhu zesafire, ukusetyenziswa kwazo okwahlukeneyo, kwaye ngakumbi, ukusebenza kwazo okugqwesileyo njengeeshefu zokukhusela i-thermocouple.

Izinto Eziphezulu Zokusetyenziswa Okufunekayo

I-Sapphire luhlobo lwe-aluminium oxide (Al₂O₃) oluyikristale kwaye lubekwe ngaphantsi kwedayimani ngokwemeko yobunzima, lufumana amanqaku ali-9 kwisikali se-Mohs. Obu bunzima bungaqhelekanga benza iityhubhu ze-sapphire zingakwazi ukumelana nokukrweleka, ukukrweleka, kunye nokuchaphazeleka koomatshini, nokuba zisetyenziswa rhoqo okanye kakhulu.

Ngaphaya kwamandla oomatshini, iityhubhu zesafire zixatyiswa kakhulu ngenxa yokumelana kwazo neekhemikhali. Zihlala zizinzile kwaye zingasebenzi xa kukho uninzi lwee-asidi, izinyibilikisi, kunye neegesi ezisabelayo, kubandakanya i-hydrogen fluoride, i-chlorine, kunye neekhompawundi zesalfure. Oku kuzivumela ukuba zisebenze ngempumelelo kwiinkqubo ezibandakanya iikhemikhali ezirhabaxa okanye i-plasma.

Ukongeza, ukusebenza kobushushu besafire kuyamangalisa. Imelana nobushushu obude obufikelela kwi-2000°C ngelixa igcina ulwakhiwo lwayo lusemgangathweni. Ukuqhuba kwayo ubushushu kuxhasa ukudluliselwa kobushushu ngokukhawuleza, uphawu olubaluleke kakhulu xa lusetyenziswa kwiinkqubo zokuva ubushushu.

Enye inzuzo ebalulekileyo kukucaca kwayo okubonakalayo kwi-ultraviolet, ebonakalayo, kunye ne-infrared wavelengths—ukusuka malunga ne-0.3 μm ukuya kwi-5 μm. Oku kwenza iityhubhu zesafire zifaneleke kwiinkqubo zokujonga ukukhanya okanye iinkqubo zokujonga ubushushu kunye nokubona ezidibeneyo.

Ii-thermocouples kunye neMfuno yoKhuselo

Ii-thermocouples zizinto ezibalulekileyo kwiinkqubo ezahlukeneyo, ukusuka kwii-oven zentsimbi kunye neenjini ze-turbine ukuya kwi-semiconductor reactors kunye nezixhobo zenkqubo yeekhemikhali. Ezi zixhobo zivelisa i-voltage ngokusekelwe kumahluko obushushu phakathi kweentsimbi ezimbini ezahlukeneyo ezidityanisiweyo kwelinye icala. Nangona ii-thermocouples ziguquguquka kwaye ziqinile, ukuvezwa kwazo ngqo kubushushu, ii-corrosive agents, kunye nomothuko woomatshini kunokunciphisa kakhulu ubomi bazo benkonzo okanye kunciphise ukuchaneka kokufundwa kobushushu.

Kulapho ke iityhubhu zesafire zisebenza khona njengeeshelufu ezikhuselayo. Ngokufaka i-thermocouple ngaphakathi kwityhubhu yesafire, i-sensor iyahlukaniswa kwindawo enzima ngelixa ivumela ukudluliselwa kobushushu okusebenzayo. Isiphumo si-sensor ehlala ixesha elide, ethembekileyo ngakumbi egcina ukuchaneka okufanayo nangona sele ichithe ixesha elide kwiimeko zokusebenza ezinzima.

Indlela iSapphire eqhuba ngayo ubushushu ivumela ubushushu ukuba bufikelele kwi-thermocouple ngokukhawuleza nangokulinganayo, nto leyo enciphisa ukubambezeleka kobushushu kwaye iphucula ixesha lokuphendula. Ngaphezu koko, ukumelana kwayo nohlaselo lweekhemikhali kuqinisekisa ukuba i-sensor ayichaphazeleki ziintsalela, ukugqwala, okanye ukwakheka kwezinto—iingxaki ezihlala zichaphazela imikhono yokukhusela yesinyithi okanye yeseramikhi.
