Txheej txheem cej luam
Lub thermistor input isolation safety barrier tuaj yeem hloov cov teeb liab Pt100 ntawm ob lub xaim thiab peb lub xaim thermistors (RTDs) hauv thaj chaw txaus ntshai mus rau hauv ib qho zis nrog 1: 1 RTD teeb liab thiab ib qho zis nrog 4 ~ 20mA teeb liab mus rau thaj chaw nyab xeeb. Nws tuaj yeem teeb tsa tau zoo, thiab qhov tseeb ntawm qhov thermal resistance tuaj yeem teeb tsa los ntawm computer software.
Cov khoom no xav tau lub hwj chim ywj pheej, nrog rau lub hwj chim cais, cov khoom nkag, thiab cov qhov tso zis.

Lus Cim: 1. Lub luag haujlwm ntawm lub zog hluav taws xob yog ib qho kev xaiv ua haujlwm, thiab cov neeg siv yuav tsum teev tseg txoj kev muab hluav taws xob thaum tso qhov kev txiav txim
Kev xaiv cov khoom siv hluav taws xob tuaj yeem xa mus rau nplooj ntawv 89 ntawm "Annex"
2. Thaum nkag mus rau peb txoj hlua RTD, nws yog qhov tsim nyog los xyuas kom meej tias peb cov xov hlau muaj qhov ntev sib npaug li ntau tau
3. Thaum nkag mus rau ob txoj hlua RTD, cov qhov thaiv kev nyab xeeb 6 thiab 5 yuav tsum yog luv luv
