Qhia kev ntsuas kub ntau yam:
Ntaus t (tooj {- constantan): -200 ~ 350℃(siab precision rau tsawg kub);
Hom k (Nickel - chromium {}}}}}}}}
Hom S (Platinum - }hdium 10-Platinum): 0 ~ 1600 Qib Siab (High Calcision rau Kev Kub Ntxhw);
Hom b (platinum - rhdium 30}} platinum-rhodium 6) rau qhov kub tshaj 1600 degree.
Haum rau ambient nruab nrab:Nthuav cov hom K / S / B rau oxidizing cua; Hom N (Nickel - chromium {}}}}}} rhiav}} rhiav}} Rhenium Series rau kev txo / nqus ib puag ncig; Siv cov tes tsho tiv thaiv (piv txwv li, hastelloy, corundum) hauv kev xeb ib puag ncig.
Tshuav Nqi Nqi thiab Ruaj Ntseg thiab Ruaj Khwv: Hom K Rau Cov Kev Lom Zem Tsis tu ncua (Siab Tus Nqi {{}}}}}} Kev Ua Ntej); Platinum - recium / siab {{}}} corrosion scenarios (ntev}} lub sij hawm ruaj khov); Hom T rau Tsawg -} kub thiab txias scenarios (siab rhiab).
Qhov tseem ceeb txuas rau hauv kev tswj kom zoo
Khoom siv tsis huv tswj:Cov khoom siv hluav taws xob yuav tsum ua raws li GB / T 16700 tus qauv; Platinum - recium series ntau dua los yog sib npaug ntawm 99.95%, txheej txheem impurity- raws li alloys<0.5% to avoid affecting thermoelectric potential stability.
Tshuaj xyuas cov txheej txheem tsim khoom:Khij lub taub hau hluav taws xob ntxig (deviation tsawg dua lossis sib txuas, noo noo {} {oxide (magnesium oxide).
Kev ntsuas hluav taws xob thiab kev ntsuas kev ruaj khov:Calibrate ib iec 60584 ua ntej xa khoom, nrog kev sib tham thermoelectric muaj peev xwm sib ntsib (piv txwv li, chav kawm ⅰ: ± 1. ± 0.004|t |)); Tshawb xyuas Drift<0.5% through high-temperature aging test (≥100h).
Tswjhwm thaum siv:Conduct regular verification (once a year), avoid over-temperature operation, store in dry, non-corrosive environments, and ensure stable cold-junction temperature during installation (equipped with compensation wires/cold-junction compensators).
