Kopano ea Thermocouple ea Liindasteri
Tlhaloso ea Sehlahisoa
An kopano ea thermocouple ea indasterike sensor ea mocheso e thehiloeng ho phello ea Seebeck. E lekanya mocheso oa mecha e fapaneng ea litaba—ho kenyeletsoa le metsi, mouoane le likhase—hammoho le libaka tse tiileng, ho pholletsa le mefuta e mengata ho tloha ho-200°C ho isa ho +1300°C, e leng se etsang hore e lokele lits'ebetso ho tloha libakeng tse mocheso o tlase ho isa ho tse mocheso o phahameng.
BAHLOLI ba fana ka liboka tsa thermocouple tsa indasteri ka mefutaK, N, E, J, le TLi entsoe ka thepa ea boleng bo holimo, li-thermocouple tsena li fana ka botsitso le ts'epo e ntle ea nako e telele, li khona ho fihlela litlhoko tsa tekanyo e tsoelang pele ea mocheso tlas'a maemo a thata a indasteri, joalo ka mocheso o phahameng, khatello e phahameng le maemo a mang a thata.
Re tšehetsa ho iketsetsa lintho ho latela litlhoko tsa hau tse ikhethileng tsa kopo, ho kenyeletsoa empa ho sa felle feela ho:
• Thepa ea selateng
• Bophara ba selateng
• Bolelele ba ho kenya
• Sebopeho sa ho kenya (mohlala, se nang le khoele, se nang le lebanta)
• Khokelo ea motlakase
Sena se netefatsa ho tsamaellana ho phethahetseng le kopanyo e se nang sekoli le sistimi ea hau.
Molao-motheo oa ho Sebetsa oa Thermocouples
Molao-motheo oa tekanyo ea mocheso oa thermocouple o thehiloe holim'a phello ea Seebeck: ha ho na le phapang ea mocheso pakeng tsa kopano ea ho lekanya (konopo e chesang) le kopano ea litšupiso (konopo e batang/ea khokahano), matla a motlakase a thermoelectric (EMF) a hlahisoa ka har'a potoloho e entsoeng ke li-conductor tse peli tse fapaneng. Ka ho lekanya EMF ena ea thermoelectric, mocheso o kopanong ea ho lekanya o ka fumanoa.
Boholo ba EMF ea thermocouple boa eketseha ha mocheso o le sebakeng seo ho lekanyetsoang ho sona. Ha e le hantle, EMF e itšetlehile feela ka thepa ea li-conductor tse peli le phapang ea mocheso lipakeng tsa libaka tseo ho lekanyetsoang ho tsona; ha e itšetlehe ka bolelele kapa bophara ba lithapo tsa thermoelement.

Litšebeliso tsa Thermocouples
• Taolo ea Ts'ebetso ea Liindasteri:Tlhokomelo ea mocheso oa lionto le liphaephe indastering ea tšepe, lik'hemik'hale, petrochemical le motlakase.
• Indasteri ea Likoloi:Tekanyo ea mocheso oa khase ea mosi, mocheso oa turbocharger, le mocheso oa catalytic converter.
• Lisebelisoa tsa Lapeng:Mekhoa ea taolo ea mocheso ka liontong, lihitara tsa metsi, liontong tsa microwave le mechini ea kofi.
• Matla le Lifofane:Tekanyo ea mocheso oa ho tuka ha mollo liturbine tsa khase le lienjineng tsa rokete.
• Saense le Lilaboratori:Lipatlisiso tsa thepa le liteko tsa kalafo ea mocheso.
