Ukohlula njani imodeli ye-thermocouple

- 2021-10-19-

Ii-thermocouples ezisetyenziswa ngokuqhelekileyo zingahlulwa zibe ngamacandelo amabini: i-thermocouples eqhelekileyo kunye ne-thermocouples engekho. Ibizwa ngokuba yi-standard thermocouple ibhekisa kwi-thermocouple amandla ayo ombane kunye neqondo lobushushu lichazwe kumgangatho wesizwe, ovumela iimpazamo, kwaye inetafile yesalathiso esemgangathweni. Inomboniso ohambelanayo wembonakalo yokukhethwa. Ii-thermocouples ezingekho mgangathweni azilungile njengemigangatho ye-thermocouples ngokwemiqathango yoluhlu lwesicelo okanye umyalelo wobukhulu. Ngokubanzi, akukho theyibhile yesalathiso engaguqukiyo, kwaye isetyenziswa ikakhulu kumlinganiselo kwezinye iimeko ezikhethekileyo.

Ii-thermocouples ezisixhenxe ezisemgangathweni, i-S, B, E, K, R, J, kunye ne-T, zi-thermocouples zoyilo oluhambelanayo e-China.

Amanani esalathisi se-thermocouples ikakhulu S, R, B, N, K, E, J, T njalo njalo. Okwangoku, S, R, B zezentsimbi thermocouple exabisekileyo, kunye N, K, E, J, T zezentsimbi thermocouple ngexabiso eliphantsi.

Oku kulandelayo yingcaciso yenombolo yesalathiso se-thermocouple
S iplatinum rhodium 10 iplatinum ecocekileyo
R platinum rhodium 13 i-platinum emsulwa
B iplatinum rhodium 30 iplatinum rhodium 6
ISilikoni yeSiliko yeNikele yeChromium
I-nickel yobhedu ecocekileyo
J intsimbi yobhedu
U-Ni-Cr-Si Ni-Si
E nickel-chromium ubhedu-nickel
(S-uhlobo thermocouple) iplatinum rhodium 10-platinum thermocouple
I-platinum rhodium i-10-platinum thermocouple (i-S-type thermocouple) yintsimbi enqabileyo ye-thermocouple. I-diameter ye-couple wire ichazwe njenge-0.5mm, kwaye impazamo evumelekileyo ngu-0.015mm. Ukwakhiwa kweekhemikhali ze-electrode efanelekileyo (SP) yi-platinum-rhodium alloy kunye ne-10% ye-rhodium, i-90% yeplatinum, kunye ne-platinum ecocekileyo ye-electrode embi (SN). Ngokuqhelekileyo eyaziwa njengeplatinam enye irhodium thermocouple. Iqondo lokushisa elide elide elisebenzayo le thermocouple yi-1300℃, kwaye iqondo lokushisa elifutshane elide liyi-1600℃.
