Yuav ua li cas paub qhov txawv ntawm cov thermocouples thiab PT100

1. Thermocouples
Lub thermocouple yog ib qho khoom siv ntsuas kub uas muaj cov khoom siv hlau sib txawv. Thaum qhov kub hloov pauv ntawm qhov sib txuas ntawm ob yam khoom sib txawv ntawm lub thermocouple, qhov sib txawv tsis muaj zog yuav raug tsim. Raws li lub hauv paus ntsiab lus ntawm cov nyhuv thermoelectric, qhov kev hloov ntawm qhov kub thiab txias tuaj yeem txiav txim siab los ntawm kev ntsuas qhov sib txawv ntawm qhov sib txawv.

Kev ntsuas kub dav dav: Thermocouples tuaj yeem ntsuas qhov kub ntawm qhov qis mus rau qhov siab heev, feem ntau ncav cuag ntau pua mus rau ntau txhiab degrees.

Thermocouples muaj cov lus teb ceev ceev thiab tuaj yeem saib xyuas qhov kub thiab txias hloov hauv lub sijhawm.

Vim lub fact tias qhov ntsuas kub ntawm thermocouple yog raws li lub hauv paus ntsiab lus ntawm kev ntsuas qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, qhov kev them nyiaj txias txias yuav tsum tau tshem tawm qhov cuam tshuam ntawm ib puag ncig ntawm qhov ntsuas.

Cov ntaub ntawv thermocouple feem ntau muaj kev tiv thaiv corrosion zoo thiab tsim nyog rau kev ua haujlwm hnyav.

2. TSI 100
PT100 yog qhov ntsuas kub ntsuas raws li cov khoom siv platinum. Lub npe "PT" hauv PT100 sawv cev rau "PlatinumTemperature", thiab tus lej "100" qhia tias tus nqi ntawm cov platinum resistor siv yog 100 ohms. Raws li kev sib raug zoo ntawm cov khoom siv platinum tsis kam thiab qhov kub thiab txias, kev hloov pauv kub tuaj yeem txiav txim siab los ntawm kev ntsuas tus nqi ntawm PT100.

Qhov ntsuas kub ntawm PT100 feem ntau tuaj yeem ncav cuag 0.1 degrees Celsius.

Cov khoom siv platinum muaj kev ruaj ntseg zoo, uas tuaj yeem ua kom muaj kev ruaj ntseg ntev ntawm cov ntsuas kub.

Kev ua haujlwm linearization yuav tsum tau: Cov yam ntxwv kub tsis kam ntawm PT100 tsis yog linear thiab yuav tsum tau ua cov linearization kom tau txais qhov ntsuas kub zoo dua.

Haum rau qhov ntsuas qhov ntsuas qhov nqaim: PT100 feem ntau yog tsim rau qhov ntsuas qhov ntsuas qhov nqaim, nrog rau kev ua haujlwm kub ntawm -200 degree C txog +600 degree C.

Nyob rau hauv cov ntsiab lus, thermocouples thiab PT100 yog ob hom kub sensors. Thermocouples txiav txim siab qhov kub thiab txias hloov los ntawm kev ntsuas qhov sib txawv uas tsim los ntawm cov nyhuv thermoelectric. Lawv muaj cov yam ntxwv ntawm qhov ntsuas kub ntawm qhov dav thiab cov lus teb ceev ceev, thiab tsim nyog rau cov xwm txheej uas muaj qhov kub thiab txias thiab hloov ceev. PT100, ntawm qhov tod tes, txiav txim siab qhov kub thiab txias raws li kev sib raug zoo ntawm cov khoom siv platinum thiab kub hloov. Nws muaj kev ruaj ntseg siab thiab tsim nyog rau cov xwm txheej uas yuav tsum tau ntsuas qhov ntsuas kub thiab qhov ntsuas qhov ntsuas qhov nqaim.
