Thermocouple Classification Compensation Hlau thiab Mob khaub thuas Kawg Kho
Kev faib tawm thiab kev them nyiaj ntawm thermocouple xov hlau
Thermocouple raws li cov ntaub ntawv sib txawv tau muab faib ua S, R, B, K, N, E, J, T8 hom standardized thermocouple. Cov hlau feem ntau siv nyob rau hauv S, R, B no peb cov thermocouples.
Cov ntaub ntawv steelmaking feem ntau siv hauv steelmaking
Thermocouple indexing thermode khoom
Platinum S-type thiab rhodium 10-platinum
Platinum R-type thiab rhodium 13-platinum
B-type platinum thiab rhodium 30-platinum thiab rhodium 6
Nyob rau hauv thermocouple nws muaj khoom tseem ceeb - nyiaj xaim, nrog lawv cov thermocouple thiab ntsuas ntaus txuas mus rau compensate rau thermocouple hlawv kub hloov los ntawm kev ua yuam kev, cov nyiaj xaim yuav tsum yog vim cov tub ntxhais hlau hlau hlau cov khoom sib txawv rau cov ntsiab lus thiab them ob qho, peb feem ntau yog siv hom nyiaj raug mob.
Zero migration txujci
Tej qhov chaw siv: Yog tias qhov txias kawg tsis 0 ℃, tab sis khov heev (xws li chaw ntsuas cua sov lossis qhov chaw cua txias).
Ua tib zoo: qhov nqi ntawm qhov ntsuas yog ntxiv rau kev ntsuas. Txij li thaum lub qhov cub txias txias tas, qhov EAB (TH, 0) yog qhov tsis tu ncua, thiab qhov nyiaj them yog tsim los ntawm qhov tsim nyog muaj nqis los ntawm kev qhia txog kev hloov ntawm qhov pes tsawg tus taw rau ntawm qhov ntsuas Tus Piv txwv: ntawm qhov ntsuas tau hloov mus rau TH qhov teev ntawm qhov chaw sov, qhov ntsuas kub ntawm tus pointer tsis yog 0 ° C tiam sis TH thaum thermoelectromotive quab yuam yog xoom. Thiab qhov sib txuam txias ntawm lub thermocouple yog TH, ces tsuas yog thaum kub kawg kub T = TH, tuaj yeem ua EAB (T, TH) = 0, kom qhov nqi thiab qhov ntsuas kub ntawm qhov kawg ntawm qhov qub. Qhov no yog qhov yooj yim, thiab ib zaug thiab rau txhua qhov, tsuav yog tus mob khaub thuas sab ntawm qhov kub ib ce nyob twj ywm hauv qhov TS tsis hloov, qhov kev qhia yeej ib txwm muaj tseeb.
Mob khaub thuas kawg txoj kev siv tshuaj ntxiv
Siv lub choj uas tsis tsim kom muaj thermocouple thermocouple vim txias kawg qhov kub hloov los ntawm kev hloov hauv thermoelectric tej zaum.
Software ua lag luam
Rau hauv lub computer system, tsis tas yuav cia siab rau cov khoom kho mob thermocouple txias kawg ua. Piv txwv, yog tias qhov sib txuam txias txias tas li tiam sis tsis yog 0 ° C, nws tsuas yog tsim nyog ntxiv rau qhov sib thooj sib ncawg ntawm qhov txias txias tom qab kuaj.
Rau qhov teebmeem ntawm kev hloov ntawm T0, koj tuaj yeem siv lub thermistor lossis lwm yam kev ntsuas los rau T0 cov lus tawm tswv yim rau hauv tshuab computer, raws li tus qauv tsim ib co kev pab cuam, tuaj yeem yuav kho. Cov teeb meem yav dhau los yuav tsum xav txog cov lus sampling channel ntxiv rau lub thermoelectromotive quab yuam yuav tsum tau muaj qhov sib txuam txias kub lub teeb liab, yog tias cov thermocouple txias hlws ris no tsis zoo li qub, tab sis kuj cais cov qauv, yog hais tias cov xov tooj ntawm cov nyob ntau heev nyiaj xaim hluav taws xob txuas mus txuas rau txhua tus neeg mob txias tib lub sijhawm, tsuas yog qhov ntsuas kub txias txias thiab ib qho kev hloov T0 input channel rau nws. Mob khaub thuas kawg concentration, rau kev txhim kho cov kev ceev ntawm cov kev ntsuas ntau kuj zoo heev.
