High-Tub kub los tiv thaiv-Kev ua haujlwm tsis zoo ntawm Ceramic Rwb thaiv tsev: Cov ntsiab lus tseem ceeb rau Thermocouple Ntev-Lub Sij Hawm tas li-Kev Ua Haujlwm Zoo
Rwb thaiv tsev kev ua tau zoo attenuation yog qhov zais zais ntawm kev ua haujlwm ntev - lub sijhawm ruaj khov ntawm kev lag luam siab -kub cua sov tshuab. Ntau cov kab ntau lawm tswj xyuas qhov kub thiab txias nyob rau theem pib ntawm kev ua haujlwm ntawm cov cuab yeej siv, tab sis maj mam muaj kev hloov pauv ntawm qhov kub thiab txias thiab ntsuas qhov ntsuas kub tsis raug tom qab ob peb lub hlis ntawm kev tsim khoom tas mus li. Kev saib xyuas niaj hnub feem ntau tsis tuaj yeem tshawb pom qhov kev laus ntawm cov rwb thaiv tsev tsis zoo, ua rau muaj kev cuam tshuam tsis tu ncua ntawm kev tsim khoom ruaj khov. Ceramic band heaters kom daws tau qhov kev lag luam qhov mob no nrog lub ultra- ruaj khov lub cev thiab tshuaj lom neeg cov khoom ntawm kev lag luam siab- zaus ceramic rwb thaiv tsev cov ntaub ntawv, paub txog ntev-lub sij hawm tiv thaiv- attenuation cua sov thiab thermocouple tas li- xyuas qhov tseeb.
Mica rwb thaiv tsev cov ntaub ntawv, feem ntau cov tsoos hluav taws xob rwb thaiv tsev nruab nrab, muaj pom tseeb siab - kub aging defects. Hauv qhov chaw ua haujlwm siab tshaj 400 degree, mica yuav maj mam pulverize thiab delaminate, thiab cov rwb thaiv tsev sab hauv yuav nthuav dav. Cov pulverized mica hmoov poob rwb thaiv tsev kev ua tau zoo, tsim cov ntsiab lus to hauv zos thiab tsis ruaj tsis khov thermal. Cov txheej txheem kev laus hloov maj mam yog qhov pom tsis pom ntawm qhov muag liab qab tab sis yuav cuam tshuam tsis tu ncua nrog cov qauv ntsuas ntsuas thermocouple, ua rau qeeb thiab qhov ntsuas kub tsis hloov pauv.
Cam khwb cia aluminium heaters cia siab rau lub plhaub hlau sealing rau kev tiv thaiv rwb thaiv tsev, tab sis lawv cov khoom siv rwb thaiv tsev sab hauv tseem muaj kev txwv siab -kub tsis kam. Nyob rau hauv lub sij hawm ntev - lub sij hawm ultra- kub ua hauj lwm tej yam kev mob, nyob rau hauv lub filling cov ntaub ntawv yuav muaj hnub nyoog thiab shrinkage, ua rau hollow rwb thaiv tsev txheej thiab tsis sib xws thaum tshav kub kub dissipation. Txawm hais tias tag nrho cov sealing kev ua tau zoo yog qhov zoo, lub rwb thaiv tsev sab hauv attenuation tseem yuav ua rau thermal teb tsis ruaj khov thiab cuam tshuam rau qhov ntsuas qhov tseeb ntawm thermocouple.
Kev lag luam siab - zaus ceramic siv nyob rau hauv ceramic heaters yog sintered ntawm ultra- kub, nrog tsis tshua muaj zog molecular qauv, tsis muaj tshuaj tiv thaiv los yog lub cev deformation nyob rau hauv siab - kub ua hauj lwm ib puag ncig. Lub rwb thaiv tsev tus nqi tseem nyob ruaj khov rau lub sijhawm ntev, tsis muaj carbonization, pulverization lossis tsis ua haujlwm. Qhov kev tiv thaiv mus tas li no los tiv thaiv- attenuation rwb thaiv tsev kev ua tau zoo ua kom ntseeg tau tias cov hluav taws xob hluav taws xob hluav taws xob ntawm lub rhaub hluav taws xob tseem zoo ib yam nyob rau hauv tag nrho cov kev pabcuam, muab qhov chaw ruaj khov thiab ruaj khov thermal teb rau qhov ntsuas kub ntawm thermocouple.
Kev ntsuas kub siab -kub aging contrast test sau cov kev hloov pauv ntawm cov rwb thaiv tsev ntawm peb cov ntaub ntawv rwb thaiv tsev tom qab 3000 teev ntawm kev ua haujlwm siab - kub thiab tshuaj xyuas qhov cuam tshuam ntawm thermocouple precision:

Cov ntaub ntawv xeem kev laus intuitively qhia txog qhov sib txawv loj hauv kev tiv thaiv - attenuation kev ua tau zoo ntawm cov ntaub ntawv rwb thaiv tsev sib txawv. Ceramic rwb thaiv tsev tswj yuav luag ruaj khov kev ua tau zoo nyob rau hauv ntev - lub sij hawm siab - kub ua hauj lwm, zoo heev expanding lub zoo precision txij nkawm voj voog ntawm thermocouple systems. Rau cov kab ntau lawm tsis tu ncua uas ua raws li xoom- lub sijhawm ua haujlwm tsis zoo- lub sijhawm ua haujlwm, qhov kev ua tau zoo no ncaj qha txhais mus rau qhov khoom ruaj khov thiab txo cov nqi kho.
Qhov tsim nyog sib piv ntawm cov khoom siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob thiab siab -ruaj khov thermocouple sensors yog tus yuam sij rau kev tsim lub sijhawm ntev - lub sij hawm ruaj khov siab -kub cua sov tshuab. Kev soj ntsuam kev ua haujlwm ntawm rwb thaiv tsev thiab kev ua tau zoo sib xws cov qauv tsim tuaj yeem ua kom muaj kev tiv thaiv zoo tshaj - attenuation zoo ntawm cov qauv ceramic thiab tuav tswj qhov kub thiab txias kom raug rau kev lag luam siab - cov khoom siv kub ua haujlwm thoob plaws lub voj voog ua haujlwm.
