Txheej txheem cej luam
Thermocouple input isolation isolation barrier with surge protection function can disolate and convert the thermocouple (TC) signals nyob rau hauv cov chaw txaus ntshai rau hauv 4-20mA tam sim no cov cim, thiab tso tawm mus rau thaj chaw nyab xeeb. Qhov kev tiv thaiv kev nyab xeeb no tau ua-nyob rau hauv qhov txias kawg them nyiaj thiab tuaj yeem tsim kho kom zoo. Qhov tseeb ntau yam ntawm cov thermocouple tuaj yeem teeb tsa los ntawm computer software. Nws muaj lub luag haujlwm ntawm lub tswb tawg tawg thiab tawm ntawm lub tswb nrov.
Cov khoom no yuav tsum muaj kev ywj pheej fais fab, nrog cov khoom siv hluav taws xob sib cais, cov tswv yim, thiab cov khoom siv tawm.
"*" sawv cev rau cov tswv yim ntawm cov thermocouple, thiab cov qauv tshwj xeeb yog sawv cev los ntawm ib tus lej (saib "Cov Lus Qhia Tawm Tawm thiab Ntau Yam" kom paub meej).
