Txheej txheem cej luam
Lub tso zis analog cais kev nyab xeeb thaiv nrog lub luag haujlwm tiv thaiv surge tuaj yeem paub txog kev xa tawm cais ntawm 4 ~ 20mA cov cim los ntawm cov cuab yeej hauv thaj chaw nyab xeeb mus rau thaj chaw txaus ntshai, tsav lub valve positioner, hluav taws xob / pneumatic converter thiab lwm yam khoom siv ntawm qhov chaw, thiab txhawb nqa kev xa mus ob txoj kev ntawm HART cov cim digital nrog wirebreak tswb muaj nuj nqi. Cov khoom no xav tau kev muab hluav taws xob ywj pheej, thiab lub zog muab hluav taws xob, cov tswv yim thiab cov zis raug cais tawm.
