K-type thermocouple ke sensor ea mocheso e sebelisoang hangata, 'me thepa ea eona e entsoe haholo ka lithapo tse peli tse fapaneng tsa tšepe. Lithapo tse peli tsa tšepe hangata ke nickel (Ni) le chromium (Cr), tse tsejoang hape e le nickel-chromium (NiCr) le nickel-aluminium (NiAl) thermocouples.
Molao-motheo oa ho sebetsa oaK-mofuta oa thermocouplee itšetlehile ka phello ea thermoelectric, ke hore, ha manonyeletso a lithapo tse peli tse fapaneng tsa tšepe a le mocheso o fapaneng, ho tla hlahisoa matla a electromotive. Boholo ba matla ana a electromotive bo lekana le phapang ea mocheso oa lenonyeletso, kahoo boleng ba mocheso bo ka khethoa ka ho lekanya boholo ba matla a electromotive.
Melemo ea mofuta oa Kli-thermocoupleskenyeletsa mefuta e mengata ea litekanyo, ho nepahala ho phahameng, botsitso bo botle, nako ea ho arabela ka potlako, le khanyetso e matla ea ho senya. Ka nako e ts'oanang, e ka sebelisoa maemong a fapaneng a thata a tikoloho, joalo ka mocheso o phahameng, oxidation, corrosion le libaka tse ling. Ka hona, li-thermocouples tsa mofuta oa K li sebelisoa haholo indastering, matla, ts'ireletso ea tikoloho, bongaka le masimo a mang.
Ha ho etsoa li-thermocouples tsa mofuta oa K, lisebelisoa le lits'ebetso tse nepahetseng li lokela ho khethoa ho netefatsa ts'ebetso ea tsona le botsitso. Ka kakaretso, lithapo tsa nickel-chromium le nickel-aluminium li na le litlhoko tse phahameng tsa bohloeki 'me li hloka mekhoa e khethehileng ea ho qhibilihisa le ho e lokisa. Ka nako e ts'oanang, tlhokomelo e lokela ho lefshoa ho netefatsa boleng le botsitso ba manonyeletso nakong ea ts'ebetso ea tlhahiso ho qoba mathata a kang ho theoha ha mocheso kapa ho hlōleha.
Ka kakaretso, li-thermocouples tsa mofuta oa K li entsoe haholo ka lithapo tsa tšepe tsa nickel le tsa chromium. Ts'ebetso ea bona e tsitsitse ebile e ka tšeptjoa, 'me e sebelisoa haholo libakeng tse fapaneng tsa tekanyo ea mocheso.

Ka holimo ke kenyelletso e khuts'oane ea thepa ea thermocouple ea mofuta oa K. Ke tšepa hore e ka u thusa ho utloisisa hantle molao-motheo oa ts'ebetso le ts'ebeliso ea sensor ena ea mocheso.
