Cov txheej txheem kom paub qhov txawv ntawm cov thermistor los ntawm cov thermocouples

Yuav ua li cas paub qhov txawv cov thermistor los ntawm cov thermocouples
Thermistor thiab thermocouples feem ntau yog siv cov khoom siv hluav taws xob los ntsuas qhov kub thiab txias, thiab lawv muaj cov yam ntxwv sib txawv thiab kev siv hauv kev siv tswv yim. Yog li, peb yuav tsum paub qhov txawv ntawm cov thermistor thiab thermocouples? Hauv qab no, peb yuav qhia los ntawm ntau yam.
1. Qhov txawv ntawm Cov Ntsiab Cai
Lub hauv paus ntsiab lus ntawm thermistor yog ntsuas qhov ntsuas kub raws li qhov cuam tshuam ntawm qhov kub thiab txias ntawm nws cov nqi tsis kam. Raws li qhov kub hloov pauv, tus nqi tiv thaiv ntawm lub thermistor yuav hloov. Thermocouples, ntawm qhov tod tes, ntsuas qhov ntsuas kub siv qhov ntsuas kub ntawm electromotive quab yuam tsim ntawm qhov chaw sib cuag ntawm ob yam khoom sib txawv.
2. Qhov sib txawv ntawm qhov kev siv
Thermistor yog tsim nyog rau ntsuas qhov ntsuas kub hauv qhov me me, feem ntau ntawm -50 degree thiab 150 degree . Thermocouples tuaj yeem ntsuas qhov ntsuas kub ntau dua, feem ntau ncav cuag ntau pua txog txhiab degrees Celsius.
3. Qhov txawv ntawm lub sijhawm teb
Lub sij hawm teb ntawm thermistor yog qhov ntev, feem ntau siv kaum vib nas this mus rau ob peb feeb kom ua tiav qhov ntsuas qhov ntsuas ruaj khov. Thiab lub sij hawm teb ntawm thermocouples yog luv luv, uas tuaj yeem cuam tshuam qhov kub thiab txias hloov ntawm lub sijhawm.
4. Qhov txawv
Kev ntsuas ntawm cov thermistor yog qhov siab, ncav cuag 0.1 degree, thiab haum rau cov xwm txheej uas yuav tsum tau muaj qhov kub thiab txias. Kev ntsuas ntawm thermocouples yog qhov qis, feem ntau nyob ib ncig ntawm 1 degree.
5. Qhov sib txawv ntawm txoj kev xaim
Thermistor feem ntau siv ob lub xaim lossis peb txoj kev xaim hlau, uas yooj yim heev. Txawm li cas los xij, cov thermocouples yuav tsum ntsuas qhov sib txawv kom tau txais qhov ntsuas kub, yog li yuav tsum muaj plaub txoj kev xaim hlau, uas yog qhov nyuaj dua.
6. Qhov sib txawv ntawm cov khoom siv
Thermistor feem ntau yog ua los ntawm cov hlau oxide lossis cov ntaub ntawv polymer. Thermocouples feem ntau siv cov khoom siv hlau xws li tooj liab, npib tsib xee, chromium, thiab lwm yam.
Zuag qhia tag nrho, thermistors thiab thermocouples muaj lawv tus kheej cov yam ntxwv thiab kev siv ntau yam hauv kev ntsuas kub. Kev xaiv qhov ntsuas kub tsim nyog yuav tsum tau txiav txim siab raws li kev ntsuas tshwj xeeb thiab ib puag ncig.
