Dab tsi yog qhov ntsia hlau -hom thermocouple

Ib tug "ntsia hlau-hom thermocouple" yog ib lo lus siv nyob rau hauv kev lag luam chaw rau ib tug threaded, assembled thermocouple. Nws cov yam ntxwv tseem ceeb tsis yog ib hom sensor sib txawv, tab sis yog qhov ntsuas qhov ntsuas kub uas yog cov cuab yeej tiv thaiv kev ruaj ntseg los ntawm kev ncaj qha mus rau hauv ib qho ua ntej - threaded qhov nyob rau hauv cov cuab yeej siv los ntawm ib tug sab nraud threaded interface. Nws yog ib qho ntawm cov qauv kev teeb tsa ntawm cov thermocouples sib dhos, ua raws li cov qauv thoob ntiaj teb IEC 60584 thiab ASTM E230, thiab yog siv dav hauv qis- rau- nruab nrab siab, me me - daim ntaub ntawv txoj kab uas hla yuav tsum tau saib xyuas tsis tu ncua.

 

Cov qauv thiab cov khoom siv

Ntsia hlau- hom thermocouples muaj plaub yam tseem ceeb:

Thermocouple Element : Siv cov qauv hlau hlau, xws li K- hom (nickel-chromium-nickel-silicon), E- hom, lossis J- hom, tsim cov peev txheej thermoelectric raws li cov nyhuv Seebeck;

Rwb thaiv tsev txheej: High-purity magnesium oxide hmoov tau ntim rau hauv lub raj tiv thaiv kom ntseeg tau tias muaj hluav taws xob rwb thaiv tsev (cov rwb thaiv tsev tsis zoo ntawm chav tsev kub siab dua lossis sib npaug ntawm 100MΩ) thiab ua kom muaj cua sov zoo;

Kev Tiv Thaiv Tube: Feem ntau siv 304 stainless hlau los yog 316L stainless hlau, uas yog corrosion-resistant thiab resistant rau mechanical shock, haum rau kev huv huv ib puag ncig xws li tshuaj lom neeg thiab zaub mov kev lag luam;

Threaded Interface: Tus qauv xov sab nraud, cov lus qhia tshwj xeeb yog M27 × 2, M20 × 1.5, lossis 1 "NPT, ua tiav kev koom tes nrog cov khoom siv lub qhov threaded.

Qee cov qauv siv cov qauv armored, qhov twg cov khoom siv thermocouple, txheej rwb thaiv tsev, thiab hlau sheath yog sib xyaw ua ke los ntawm kev kos duab, txhim kho kev co kuj thiab cov lus teb ceev (lub sij hawm thermal teb tsawg dua los yog sib npaug li 10s).

 

Qauv Kev Cai Sau Npe thiab Kev Lag Luam Codes

Cov qauv kev lag luam hauv tsev feem ntau ua raws li JB/T 8622 tus qauv naming system, nrog rau hom qauv ntawm:

NWS-230

W: ntsuas kub

R: Thermocouple

N: Nickel-chromium-nickel- silicon (K- hom)

K: Armored hom (yeem)

2: Tsau xov mounting

30: Xov specification M27 × 2

Lwm cov qauv muaj xws li:

WZP-230 (tus pas ntsuas kub tsis kam, tib lub qauv)

WRNT-02 (Imitation imported hom, M6 × 1.5 xov)

WRNKD2-04B (hom tawg-pov thawj)

Cov ntawv thov tshwj xeeb ua haujlwm

Explosion-pov thawj ib puag ncig: Siv tawg- cov ntaub ntawv pov thawj (xws li JWB/P series), ntsib Ex d IIC T6 Explosion- pov thawj ntsuas, haum rau refineries thiab tshuaj reactors;

Nqus / inert cua: Siv tungsten-rhenium thermocouples (W-5Re/W-26Re), nrog rau lub raj tiv thaiv uas muaj cov roj inert los tiv thaiv qhov kub thiab txias oxidation, haum rau semiconductor wafer annealing furnaces;

Daim ntawv thov kev tu cev: Cov raj tiv thaiv nrog daim iav polishing (Ra Tsawg dua lossis sib npaug ntawm 0.4μm), ua raws li GMP cov qauv, siv rau hauv kev siv tshuaj tua kab mob autoclaves thiab cov kab noj zaub mov.

Lub ntsiab ntawm cov ntsia hlau -hom thermocouple yog nws "txoj kev txhim kho" es tsis yog nws "sensing txoj cai." Nws tus nqi yog nyob rau hauv kev ua tiav qhov kev sib cuag ntawm qhov ntsuas kub ntawm tus nqi qis thiab nrog kev tswj xyuas siab, ua rau nws yog ib qho ntawm cov khoom siv dav dav siv hauv cov tshuab automation.
