Lub sij hawm teb ntawm S-hom thermocouple yog dab tsi?

Lub sij hawm teb ntawm S- hom thermocouple feem ntau nyob ntawm ob peb vib nas this mus rau 150 vib nas this, nrog rau cov nqi tshwj xeeb yog nyob ntawm nws cov qauv tsim, cov khoom siv ntawm cov ntaub thaiv npog, txoj kab uas hla ntawm cov thermocouple hlau, thiab lub cev lub cev ntawm qhov ntsuas nruab nrab. Raws li cov ntaub ntawv ntau- qhov chaw, lub sij hawm thermal teb ntawm tus qauv muaj S- hom thermocouple feem ntau tsawg dua 150 vib nas this. Nyob rau hauv optimized designs los yog tshwj xeeb daim ntaub ntawv, lub sij hawm teb yuav luv luv mus rau 3-6 vib nas this, thiab txawm ib tug ceev teb ntawm tsawg tshaj li los yog sib npaug zos rau 100ms yuav ua tau tiav nyob rau hauv lub teeb liab hloov dua siab tshiab module. Qhov taw qhia kev ua tau zoo no ncaj qha ntsig txog qhov tseeb- lub sijhawm ua haujlwm thiab kev ua haujlwm tsis zoo ntawm kev ntsuas qhov ntsuas kub, thiab yog qhov tseem ceeb ntawm cov txheej txheem ntsuas kub siab -.

 

I. Kev txhais thiab kev txhais lus ntawm lub sij hawm teb

Lub sij hawm teb ntawm lub thermocouple yog hais txog lub sij hawm uas yuav tsum tau rau nws cov teeb liab tso zis kom ncav cuag 63.2% ntawm qhov kev hloov pauv thaum ntsuas qhov ntsuas kub dhau ib kauj ruam hloov (piv txwv li, lub sij hawm tas li τ). Qhov no tsis yog lub sijhawm yuav tsum tau ua kom tiav kev ruaj ntseg- kom ua tiav cov lus teb ntau dua 95%, feem ntau yog 3-5 npaug ntawm τ tus nqi xav tau. Yog li nominal "<150 seconds" means that under ideal conditions, it will approach a stable value within approximately 7–15 minutes.

S-hom thermocouples, ua los ntawm cov hlau muaj txiaj ntsig (platinum-rhodium 10-platinum), muaj lub sijhawm teb qeeb vim lawv cov thermal conductivity thiab cov yam ntxwv ntawm cov cua sov. Txawm li cas los xij, lawv qhov kev ua tau zoo tuaj yeem txhim kho tau zoo los ntawm kev ua kom zoo dua qub.

 

II. Cov ntsiab lus tseem ceeb cuam tshuam rau lub sijhawm teb

Hlau txoj kab uas hla thiab ntsuas qhov kawg qauv: Lub thinner cov hlau, qhov me me lub tshav kub muaj peev xwm, thiab cov lus teb sai dua. S-hom thermocouples feem ntau siv cov hlau diameters ntawm Φ0.5mm. Txo qhov no kom qis dua Φ0.3mm tuaj yeem txo lub sijhawm teb, tab sis nws yuav txo cov neeg kho tshuab lub zog thiab nkag siab, cuam tshuam rau lub sijhawm ntev -.

Kev Tiv Thaiv Sheath Khoom thiab Thickness: Cov ntaub thaiv npog yog qhov tseem ceeb ntawm thermal kuj. Hlau sheaths (xws li 316L stainless hlau) muaj thermal conductivity zoo dua li ceramic sheaths, ua rau cov lus teb sai dua; thaum ob - txheej corundum sheaths, txawm hais tias tiv taus kub thiab corrosion, ua rau lub sijhawm teb ntev. Cov qauv hlau liab qab muab cov lus teb ceev tshaj plaws tab sis muaj kev cuam tshuam rau kev sib kis thiab oxidation, ua rau lawv tsuas yog tsim nyog rau qhov chaw huv, tsis muaj zog.

Ntsuas Nruab Nrab Hom thiab Flow State

Nyob rau hauv cov roj tseem, cov hluav taws xob hloov hluav taws xob tsis tshua muaj qis, yuav tsum tau tshaj 30 feeb kom ncav cuag thermal sib npaug, ua rau cov lus teb qeeb heev.

Nyob rau hauv cov kua los yog siab - gas flows, convective tshav kub hloov yog txhim khu kev qha, thiab lub sij hawm teb yuav luv luv mus rau qhov kev txiav txim ntawm vib nas this.

Hauv cov xwm txheej hnyav xws li ntsuas kub ntawm cov hlau molten, nrog kev siv ceev ceev - lub tes tsho tiv thaiv pov tseg, ntsuas kub tuaj yeem ua tiav hauv 1-2 vib nas this.

Installation Method thiab Insertion Qhov tob

Qhov tob tob yuav tsum tsis pub tsawg tshaj 10 npaug ntawm txoj kab uas hla ntawm lub tes tsho tiv thaiv kom ntseeg tau tias muaj kev sib cuag ntawm qhov ntsuas kawg thiab qhov nruab nrab. Kev teeb tsa hauv thaj chaw uas muaj qhov ntsuas kub me me lossis qis qis qis yuav ua rau cov lus teb qeeb.

 

III. Lub Sijhawm Teb Lub Sijhawm Zoo Tshaj Plaws thiab Daim Ntawv Thov Scenarios

Daim ntawv thov Scenario	Teb Sijhawm	Nta
Standard Industrial S-hom Thermocouple	< 150 seconds	Haum rau ruaj khov- xeev siab- qhov kub thiab txias ib puag ncig xws li iav kilns thiab cov txheej txheem firing ceramic.
Fast Response Type (Optimized Structure)	3-6 vib nas this	Siv cov xov hlau zoo thiab nyias nyias - cov phab ntsa hlau rau kev ntsuas qhov kub thiab txias.
Kub Transmitter Integrated Module	Tsawg dua lossis sib npaug li 100ms	Optimized teeb liab ua, tsis sensor lub cev teb.
Tseem Gas Ib puag ncig	Ntau dua lossis sib npaug li 30 feeb (mus txog qhov sib npaug)	Thermal equilibrium lub sij hawm yuav tsum tau txiav txim siab nyob rau hauv tiag tiag siv; qhov no tsis yog lub sijhawm teb qhia los ntawm cov txheej txheem kev ua haujlwm.

Lus Cim: "Lub Sij Hawm Teb" ≠ "Tsuas Ntsuas Ntsuas Qhov Ntsuas". Hauv kev ua haujlwm tiag tiag, xws li ntsuas qhov kub ntawm cov hlau molten hauv lub tshuab ua hlau, txawm hais tias cov lus teb ntawm lub sensor yog ceev (milliseconds), qhov tob tob thiab lub sijhawm nyob hauv yuav tsum tau ua kom tau txais qhov tseeb.

 

IV. Kev xaiv engineering thiab cov lus pom zoo siv

Yog tias qhov tseeb siab thiab ntev - lub sij hawm ruaj khov yuav tsum tau, thiab lub sij hawm teb ntev me ntsis yog qhov ua tau, S-hom thermocouples nrog ob npaug - txheej ceramic tiv thaiv yuav tsum nyiam dua.

Rau kev siv nyob rau hauv kev saib xyuas qhov kub thiab txias los yog kev tswj ceev ceev, zoo - txoj kab uas hla txuas txuas, ib qho - txheej hlau tiv thaiv cov raj, lossis cov qauv hlau liab qab yuav tsum raug xaiv, thiab tom qab- kev tsim kho yuav tsum muaj zog.

Thaum lub sij hawm siv, kev them nyiaj txias junction, teeb liab filtering, thiab calibration tsis tu ncua yog qhov tseem ceeb rau kev ntsuas qhov tseeb, tshwj xeeb tshaj yog nyob rau hauv cov tshuab nrog lub sij hawm teb qeeb uas qhov kev ua yuam kev dynamic muaj ntau dua rau kev sib sau.
