Txheej txheem cej luam
RTD input kev sib cais kev nyab xeeb teeb meem tuaj yeem hloov pauv ob lub xaim lossis peb lub xaim thermistor (RTD) cov teeb liab hauv thaj chaw muaj kev phom sij rau hauv 4-20mA cov teeb liab tam sim no thiab tso tawm mus rau thaj chaw nyab xeeb. Nws tuaj yeem tsim kho tau zoo, thiab qhov tseeb ntau yam ntawm cov thermal kuj tuaj yeem teeb tsa los ntawm khoos phis tawj software. Nws muaj lub luag haujlwm ntawm lub tswb tawg tawg thiab tawm ntawm lub tswb nrov.
Cov khoom no xav tau lub zog ywj pheej, nrog cov khoom siv hluav taws xob cais tawm, cov tswv yim, thiab cov khoom siv tawm.
"*" sawv cev rau hom input ntawm lub thermistor, thiab cov qauv tshwj xeeb yog sawv cev los ntawm tus lej (saib "Input Signal Type and Range Table" kom paub meej).
Hom teeb liab input thiab ntsuas ntau yam
| Code | RTD qauv | Kev ntsuas ntau | Yam tsawg kawg nkaus | Kev hloov siab lees txim |
| 1 | g53 ua | -50 ~ 150 ℃ | 20 ℃ | 0.2 ℃ / 0.1% |
| 2 | Nrog 50 | -50 ~ 150 ℃ | 20 ℃ | 0.2 ℃ / 0.1% |
| 4 | Pt 100 | -200 ~ 850 ℃ | 20 ℃ | 0.2 ℃ / 0.1% |
| 6 | Pt 1000 | -200 ~ 850 ℃ | 20 ℃ | 0.2 ℃ / 0.1% |
| 7 | Nws 1000 | -60 ~ 250 ℃ | 20 ℃ | 0.2 ℃ / 0.1% |
Piv txwv li: cais kev nyab xeeb barrier Pt100 input, kub ntau yam 0 ~ 400 ℃, ob outputs nrog 4 ~ 20mA, lub hwj chim mov yog 20 ~ 35VDC. Tus qauv yog PHD-22TZ-4141 (0 ~ 400 ℃), qhov ntsuas qhov ntsuas tuaj yeem teeb tsa rau qhov ntsuas qhov ntsuas ntawm 0 ~ 400 ℃ los ntawm lub computer.
