1.PT100 kub sensorsFeem ntau yog siv los ua ke nrog cov cuab yeej tso saib, cov cuab yeej kaw lus, cov khoom siv hluav taws xob, thiab lwm yam. Ncaj nraim ntsuas qhov kub ntawm cov kua, chav thiab roj nruab nrab thiab cov khoom nto nyob rau hauv thaj tsam ntawm -200 ° C ~ 500 ° C hauv ntau cov txheej txheem ntau lawm.Txhawm rau txiav txim siab seb nws zoo lossis phem, tsuas yog siv lub tshuab ntsuas digital los ntsuas nws.
2. Cov yam ntxwv ntawm PT100 kub sensor yog tias ob lub tso zis terminals (qee zaum ntau lub davhlau ya nyob twg) txuas nrog multimeter (txawm hais tias muaj qee qhov kev tiv thaiv tus nqi).Yog hais tias qhib Circuit Court yuav phem, nws yog undoubtedly thawj kauj ruam nyob rau hauv qhov tseeb txiav txim.Tus nqi tsis kam ntawm thermal kuj yog tsau.Piv txwv li, qhov kub thiab txias ntawm PT100 yog nyob ib ncig ntawm 110 ohms, thiab qhov kub thiab txias ntawm CU50 yog nyob ib ncig ntawm 55 ohms.Cov zis ntawm lub thermocouple yog tus nqi voltage.Ntawm qhov kub thiab txias, nws yuav tso tawm qhov hluav taws xob hluav taws xob feem ntau ntawm ob peb mus rau kaum tawm millivolts, uas tuaj yeem ntsuas nrog cov ntaub ntawv voltage ntawm multimeter.
3. Cov zis voltage ntawm lub thermocouple tsuas yog ob peb mV, nyob ntawm qhov tseeb ntawm multimeter.Digital multimeter tuaj yeem siv rau kev ntsuas ntxhib thiab kev txiav txim siab.Cov zis ntawm lub thermocouple yog nyob rau hauv qhov kev txiav txim ntawm millivolts.Nws tsis tuaj yeem ntes nws cov zis nrog lub multimeter, tab sis nws tuaj yeem ntsuas tau rau nws qhov txuas ntxiv.Feem ntau, ntev npaum li qhov galvanic (qhov twg ob lub xov hlau txuas) txuas nrog, tsis muaj oxidation, tsis muaj kev puas tsuaj, thiab feem ntau tsis muaj teeb meem.Yog li ntawd, nyob rau tib lub sijhawm, nws tuaj yeem raug tshem tawm los ntawm lub plhaub rau kev kuaj pom.Txhawm rau kuaj xyuas tiag tiag, nws yog qhov yuav tsum tau siv tus qauv thermocouple los sib piv thiab ntsuas tus nqi millivolt nws cov zis.
4. Cov saum toj no yog txoj kev nrhiav kom paub seb tusPT100 kub sensoryog ib yam khoom.Kuv vam tias yuav pab tau sawv daws.Yog tias koj muaj lus nug, koj tuaj yeem tiv tauj peb cov neeg ua haujlwm technical.
