Txheej txheem cej luam
Lub thermocouple input isolation safety barrier muaj peev xwm cais thiab hloov cov thermocouple (TC) cov teeb liab hauv thaj chaw txaus ntshai mus rau hauv 4-20mA tam sim no, thiab tso tawm mus rau thaj chaw nyab xeeb. Lub barrier safety barrier no muaj kev them nyiaj rau kev sib tshuam txias thiab tuaj yeem teeb tsa tau zoo. Qhov ntau thiab tsawg ntawm thermocouple tuaj yeem teeb tsa los ntawm software computer. Nws muaj cov haujlwm ntawm lub tswb ceeb toom tawg hlau thiab lub tswb ceeb toom tawm ntawm qhov ntau thiab tsawg. Cov khoom no xav tau lub zog hluav taws xob ywj pheej, nrog rau lub zog hluav taws xob cais, cov qhov nkag, thiab cov qhov tso tawm. "*" sawv cev rau hom qhov nkag ntawm thermocouple, thiab tus qauv tshwj xeeb yog sawv cev los ntawm tus lej (saib "Input Signal Type and Range Table" kom paub meej ntxiv).

| 8 | N | -200~1300℃ | 50 ℃ | 0.5 ℃ / 0.1% |
Piv txwv li: thaum lub tswv yim yog 2 lub tswv yim nrog K-couple, qhov kub thiab txias yog 0 ~ 1200 ℃, 2 qhov tso zis 4 ~ 20mA, lub zog muab 20 ~ 35VDC, ces tus qauv yuav tsum yog PHD-22TT-1111 (0 ~ 1200 ℃).
Qhov ntsuas ntau yam tuaj yeem teeb tsa rau qhov teev tseg 0 ~ 1200 ℃ los ntawm lub khoos phis tawj.
