Qhov tseem ceeb ntawm Matching Thermocouple Models nrog Kub Khiav Kub Kub Controllers

Thermocouple sensing Cheebtsam thiab cov tswj qhov kub thiab txias yuav tsum ua hauj lwm zoo kawg nkaus ua ke rau qhov kub khiav lub kaw lus kaw tag nrho - voj voog tswj kub. Lub hauv paus rau kev saib xyuas qhov kub thiab txias thiab txhim khu kev qha cua sov yog qhov zoo sib xws ntawm cov qauv thiab qhov tsis sib xws ntawm ob. Cov qauv tsis sib xws yuav ua rau cov ntaub ntawv kub tsis sib haum tam sim ntawd, tsis xwm yeem cua sov logic, thiab cov khoom siv tsis tu ncua, txhua yam ua rau muaj ntau yam teeb meem tsis pom zoo nrog kev txhaj tshuaj molding.

Ua ntej ntawm tag nrho cov, cov txheej txheem thermoelectric tej zaum yuav txawv ntawm cov thermocouple hom. Cov thermocouples sib txawv, xws li K-type, J-type, T-type, thiab lwm yam, muab cov teeb liab sib txawv ntawm qhov kub thiab txias. Tus tswv tsev tsis tuaj yeem lees paub qhov kev tawm tswv yim hluav taws xob lub teeb liab yog tias tus qauv thermocouple siv rau hauv kev tsis meej pem yam tsis muaj qhov sib piv ntawm tus tswj kev teeb tsa, uas ua rau muaj qhov tsis sib xws ntawm qhov tshwm sim thiab qhov ntsuas kub tiag tiag. Piv txwv li, nws tsis tuaj yeem ua qhov kev ntsuas kub zoo thaum J-hom thermocouples siv rau ntawm K- hom kev tswj qhov kub thiab txias vim tias qhov ntsuas kub tau pom yuav siab dua lossis qis dua qhov ntsuas kub tiag tiag.

Thib ob, qib precision thiab qib kub tsis kam yuav tsum sib haum ib txhij. Ordinary economical controllers yog txuam nrog cov qauv precision pa thermocouples kom ua tiav cov nqi tsim nyog; high-cov tswj qhov kub thiab txias yog qhov tsim nyog rau siab- qhov tseeb qis- drift thermocouples, uas tuaj yeem siv tag nrho cov txiaj ntsig ntawm kev tswj qhov kub thiab txias. Kev tswj hwm kev ua haujlwm siab ntawm tus tswv tsev tsis tuaj yeem ua tiav yog tias siab - cov tswj hwm qhov tseeb tau ua ke nrog qis- qhov tseeb ntawm cov thermocouples; conversely, siv high -zoo thermocouples nrog qis- qib controllers yuav pov tseg qhov kev paub txog kev ua tau zoo thiab ua tsis tau raws li qhov xav tau ntawm qhov kub thiab txias.

Tus tswj qhov kub thiab txias ntawm cov hlau ncej txhais, teeb liab kis tau tus mob, thiab txias junction them nyiaj tsis yog tag nrho cov teev nyob rau hauv cov nqe lus ntawm kab teeb liab txuam. Kev ua yuam kev nyob rau hauv qhov kub ntawm qhov kub thiab txias vim qhov tsis sib xws ntawm cov thermocouple them nyiaj xaim yuav ua rau muaj qhov sib txawv ntawm qhov kub thiab txias uas tsis tuaj yeem raug tshem tawm los ntawm tib neeg calibration. Lub tshuab ntsuas kub tsuas tuaj yeem suav qhov tseeb thiab hloov cov teeb liab hluav taws xob xa los ntawm lub thermocouple thiab ua tiav qhov ntsuas kub tsis tu ncua ntawm cov cua sov pib thiab nres thaum ob qho tib si zoo sib xws.

Qhov teeb meem tsis sib xws, uas yog qhov tseem ceeb ntawm ntau qhov tsis txaus ntseeg qhov ntsuas kub tsis xwm yeem, feem ntau tsis quav ntsej los ntawm cov neeg ua haujlwm saib xyuas thaum hloov cov thermocouples ntawm ntau hom hauv tiag tiag - ntiaj teb ntawm - siv qhov chaw kom yooj yim. Thaum hloov cov khoom siv, nws yog ib qho tseem ceeb kom paub tseeb tias qhov ntsuas kub ntawm qhov ntsuas qhov sib txawv ntawm cov thermocouple hom ua ntej, sib koom ua ke tus tswv tsev qhov chaw teeb tsa sab hauv tom qab hloov, thiab ua qhov ntsuas kub ntsuas. Ntxiv rau kev tswj xyuas lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov kub khiav kub tswj qhov system, txo tus nqi ntawm cov khoom siv tsis raug thiab cov khoom siv tsis ua haujlwm, thiab tsim cov txiaj ntsig kev lag luam ruaj khov rau kev txhaj tshuaj molding ntau lawm, kev sib koom ua ke qauv tuaj yeem ua rau kev ua haujlwm zoo ntawm cov thermocouples thiab cov tswj kub.
