Mokhoa oa ho khetholla mofuta oa thermocouple

Li-thermocouples tse sebelisoang ka tloaelo li ka aroloa ka mekhahlelo e 'meli: li-thermocouples tse tloaelehileng le li-thermocouples tse sa tloaelehang. Thermocouple e bitsoang standard thermocouple e bolela thermocouple eo matla a eona a thermoelectric le thempereichara e boletsoeng ho ea ka maemo a naha, e lumellang liphoso, 'me e na le tafole e tsitsitseng ea indexing. E na le ponahalo e ts'oanang ea ponts'o bakeng sa khetho. Li-thermocouples tse sa tloaelehang ha li tšoane le li-thermocouples tse tloaelehileng ho latela mefuta ea ts'ebeliso kapa tatellano ea boholo. Ka kakaretso, ha ho na tafole e lumellanang ea indexing, 'me li sebelisoa haholo-holo bakeng sa ho metha liketsahalong tse ling tse khethehileng.

Li-thermocouples tse supileng tse emeng, S, B, E, K, R, J, le T, ke li-thermocouples tsa moralo o ts'oanang oa China.

Linomoro tsa indexing tsa thermocouples haholo-holo S, R, B, N, K, E, J, T joalo-joalo. Ho sa le joalo, S, R, B ke tsa tšepe ea bohlokoa ea thermocouple, 'me N, K, E, J, T ke ea thermocouple ea tšepe e theko e tlaase.

(S-mofuta oa thermocouple) platinum rhodium 10-platinum thermocouple
Platinum rhodium 10-platinum thermocouple (S-type thermocouple) ke tšepe ea bohlokoa ea thermocouple. Bophara ba terata ea banyalani bo hlalosoa e le 0.5mm, 'me phoso e amohelehang ke -0.015mm. Motsoako oa lik'hemik'hale oa electrode e ntle (SP) ke motsoako oa platinum-rhodium o nang le 10% rhodium, 90% platinum, le platinum e hloekileng bakeng sa electrode e fosahetseng (SN). Ka tloaelo e tsejoa e le single platinum rhodium thermocouple. Mocheso oa nako e telele o sebetsang oa thermocouple ena ke 1300℃, 'me mocheso oa nako e khutšoanyane o sebetsang ke 1600℃.
