Yuav ua li cas kom ntseeg tau qhov tseeb ntawm qhov ntsuas kub ntawm qhov ntsuas kub tsis tshua muaj siab?

Kev ntsuas kub kom raug hauv qab qhov kub tsis tshua muaj siab yog ib txoj haujlwm nyuaj. Thaum nws cuam tshuam nrog cov thermocouples, lawv yuav yog cov cuab yeej siv tau zoo txawm li cas los xij xav tau kev txiav txim siab tshwj xeeb.
Kev xaiv khoom yog qhov tseem ceeb. Rau qhov kub tsis tshua muaj siab, cov tshuaj uas ua rau lawv lub tsev thiab qhov tseeb ntawm qhov kub siab heev yuav tsum tau xaiv. Thermocouples crafted los ntawm tshwj xeeb alloys xws li chromel-alumel los yog tooj liab-constantan tej zaum yuav tsim nyog rau tsawg-kub daim ntaub ntawv. Cov tshuaj no yuav tsum tau ceev faj txog kev txiav txim siab kom paub tseeb tias lawv tau txais qhov xav tau rhiab heev thiab sib npaug ntawm qhov kub qis.
Zoo rwb thaiv tsev thiab shielding. Ntawm qhov kub tsis tshua muaj siab, kev rwb thaiv tsev hloov mus rau qhov tseem ceeb dua kom txuag tau koj qhov sov so thiab hluav taws xob cuam tshuam. Cov rwb thaiv tsev nyob thoob plaws lub thermocouple xov hlau yuav tsum tau tsim los txo qhov kub thiab txias hloov thiab tiv thaiv lub sensor los ntawm sab nraud influences. Shielding tseem yuav yog qhov tseem ceeb los cawm koj txoj kev cuam tshuam ntawm electromagnetic uas yuav cuam tshuam rau qhov tseeb ntawm qhov ntsuas.
Calibration thiab txheeb xyuas. Tsis tu ncua calibration yog ib qho tseem ceeb los ua kom paub qhov ntsuas kub kom raug. Nyob rau hauv cov xwm txheej kub tsis tshua muaj siab, calibration yuav tsum tau ua kom tiav cov kev siv cov kev cai siv uas yog traceable rau lub teb chaws thoob plaws lub teb chaws los yog thoob ntiaj teb ntsuas kub. Cov txheej txheem calibration tshwj xeeb thiab cov txheej txheem tuaj yeem raug suav nrog rau cov xwm txheej xav tau tshwj xeeb ntawm kev ntsuas kub qis. Thermocouples yuav tsum tau calibrated ntawm ob peb yam nyob rau hauv qhov kub thiab txias ntau yam ntawm kev nyiam ua kom muaj tseeb nyob rau hauv tag nrho ntau yam.
Kev txhim kho thiab tswj. Kev teeb tsa kom raug thiab kev tswj hwm ntawm cov thermocouple yog qhov tseem ceeb rau kev ntsuas kom raug. Lub thermocouple yuav tsum tau tsim nyob rau hauv ib tug yam ntxwv uas guarantees zoo heev thermal kov nrog cov khoom raug ntsuas nrog tawm qhia tej yam tsis raug ntxiv. Kev saib xyuas yuav tsum tau ua nyob rau qee qhov chaw ntawm kev teeb tsa kom tsis txhob muaj kev ntxhov siab lossis ua rau muaj kev puas tsuaj rau cov xaim thermocouple. Tsis tas li ntawd, kev tswj hwm lub thermocouple ceev faj kom txuag koj cov neeg kho tshuab kev puas tsuaj lossis kev kis kab mob yog qhov tseem ceeb.
Kev nrhiav thiab ua cov ntaub ntawv. Cov ntaub ntawv tau txais lub tshuab siv los ntsuas cov khoom siv thermocouple yuav tsum tau tsim los rau cov ntawv thov kub qis. Nws yuav tsum muaj kev txiav txim siab ntau dhau thiab raug thiab muaj peev xwm saib xyuas cov ntsuas qis-theem uas tsim los ntawm txoj kev ntawm cov thermocouple ntawm qhov kub tsis tshua muaj siab. Cov ntaub ntawv ua cov algorithms yuav tsum tau ua kom zoo ntxiv rau tus account rau tej yam tsis yog linearities los yog glide nyob rau hauv lub thermocouple teb. Kev lim dej thiab qhov nruab nrab cov tswv yim yuav raug siv los txhim kho qhov tseeb ntawm qhov ntsuas kub.
