Lithapo tsa matšeliso a thermocouple le tsona li ka bitsoa lithapo tsa lisebelisoa, kaha li sebelisoa ho lekanya mocheso. Mohaho o ts'oana le thapo ea lisebelisoa tsa para empa lisebelisoa tsa conductor li fapane.

Thermocouples e sebelisoa ts'ebetsong ho lemoha mocheso 'me e hokahane le pyrometers bakeng sa pontšo le taolo. Thermocouple le pyrometer li tsamaisoa ka motlakase ke lithapo tsa katoloso ea thermocouple / lithapo tsa matšeliso a thermocouple. Likhondara tse sebelisoang bakeng sa likhoele tsena tsa thermocouple li tlameha ho ba le thepa e tšoanang ea thermo-electric (emf) joalo ka ea thermocouple e sebelisetsoang ho utloa mocheso.

Semela sa rona se etsa haholo mofuta oa KX, NX, EX, JX, NC, TX, SC/RC, KCA, KCB terata e lefellang thermocouple, 'me e sebelisoa ho lisebelisoa tsa ho lekanya mocheso le likhoele. Lihlahisoa tsa rona tsa matšeliso a thermocouple kaofela li entsoe ho latela GB/T 4990-2010 'Alloy wires of extension and compensing cables for thermocouples' (Chinese National Standard), le IEC584-3 'Thermocouple part 3-compensating wire' (Tekanyetso ea machaba).

Kemelo ea komporo. terata: khoutu ea thermocouple+C/X, mohlala, SC, KX
X: Khutšoane bakeng sa katoloso, ho bolela hore motsoako oa terata ea matšeliso o tšoana le motsoako oa thermocouple.
C: Nako e khutšoanyane bakeng sa matšeliso, e bolela hore motsoako oa terata ea matšeliso o na le litlhaku tse tšoanang le motsoako oa thermocouple ka mocheso o itseng.
