Indlela yokuhlukanisa imodeli ye-thermocouple

Ama-thermocouples asetshenziswa kakhulu angahlukaniswa ngezigaba ezimbili: ama-thermocouples ajwayelekile nama-thermocouples angajwayelekile. I-thermocouple ejwayelekile ebizwa nge-thermocouple isho amandla we-thermoelectric namandla nokushisa kwayo okushiwo kuzinga likazwelonke, elivumela amaphutha, futhi linethebula lokukhomba elijwayelekile elihambisanayo. Inokubukeka kwesiboniso okuhambisanayo kokukhethwa. Ama-thermocouples angajwayelekile awafanelekile njengama-thermocouples ajwayelekile ngokwebanga lohlelo lokusebenza noma ukuhleleka kobukhulu. Ngokuvamile, alikho ithebula lenkomba elingaguquguquki, futhi lisetshenziselwa ukukalwa ngezikhathi ezithile ezikhethekile.

Ama-thermocouples ayisikhombisa ajwayelekile, S, B, E, K, R, J, kanye no-T, angama-thermocouples omklamo ongashintshi e-China.

Izinombolo zokukhomba zama-thermocouples ikakhulukazi ngu-S, R, B, N, K, E, J, T njalonjalo. Okwamanje, i-S, R, B ingeye-thermocouple yensimbi eyigugu, kanti i-N, K, E, J, T ingeye-thermocouple yensimbi eshibhile.

Okulandelayo yincazelo yenombolo yenkomba ye-thermocouple
S iplatinum rhodium 10 iplatinamu emsulwa
R iplatinum rhodium 13 iplatinamu emsulwa
B iplatinum rhodium 30 iplatinum rhodium 6
I-Silicon ye-Nickel Chromium Nickel
I-nickel yethusi yethusi emsulwa
J iron nickel yethusi
I-N Ni-Cr-Si Ni-Si
I-nickel-chromium yethusi-nickel
(Uhlobo lwe-S thermocouple) i-platinum rhodium 10-platinum thermocouple
I-platinum rhodium 10-platinum thermocouple (S-type thermocouple) iyi-thermocouple yensimbi eyigugu. Ububanzi bentambo yombhangqwana bucaciswe njengo-0.5mm, futhi iphutha elivumelekile ngu--0.015mm. Ukwakheka kwamakhemikhali okuzisholo kwe-electrode ephozithivu (SP) ingxubevange ye-platinum-rhodium ene-rhodium engu-10%, iplatinum engu-90%, kanye neplatinamu emsulwa ye-electrode eyinegethivu (SN). Eyaziwa kakhulu ngokuthi i-single platinum rhodium thermocouple. Izinga lokushisa eliphezulu lesikhathi eside elisebenzayo lale thermocouple ngu-1300℃, futhi izinga lokushisa eliphezulu lesikhathi esifushane liyi-1600℃.
