Txheej txheem cej luam
Lub tshuab hluav taws xob analog tso zis cais kev nyab xeeb 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. Cov khoom no xav tau kev muab hluav taws xob ywj pheej, thiab kev muab hluav taws xob, kev nkag thiab tso zis raug cais tawm.
| Fais fab mov | 20 ~ 35V DC, Kev siv hluav taws xob: ≤90mA (lub zog muab hluav taws xob, 20mA tso zis) |
| Lub teeb liab nkag | 4 ~ 20mA (HART) |
| Teeb liab tso zis | 4 ~ 20mA (HART) |
| Kev tiv thaiv thauj khoom | Thaum tso zis 20mA, 0 ~ 800 Ω (kho tau) |
| Tus naj npawb ntawm cov channel nkag thiab tawm | 2 lub tswv yim 2 qhov tso zis |
| Cov khoom siv hauv tsev siv tau | Lub tshuab hloov pauv valve, lub tshuab hloov pauv hluav taws xob/pneumatic |
| Cov ntsuas kub | Kub ua haujlwm: -20 ℃ ~ + 60 ℃, kub cia: -40 ℃ ~ + 80 ℃ |
| Cov av noo sib piv | 10% ~ 95% RH tsis muaj dej noo |
| Lub zog dielectric | Nruab nrab ntawm sab uas muaj kev nyab xeeb thiab sab uas tsis muaj kev nyab xeeb (≥ 3000VAC/min); nruab nrab ntawm lub hwj chim thiab qhov kawg uas tsis muaj kev nyab xeeb (≥ 1500VAC/min) |
| Kev tiv thaiv rwb thaiv tsev | ≥100MΩ (nruab nrab ntawm cov tswv yim / tso zis / fais fab mov) |
| Qhov ntev sab nraud | Thickness 12.5mm x dav 108mm x siab 118mm |
| Kev sib raug zoo ntawm hluav taws xob | Raws li IEC 61326-1 (GB / T 18268), IEC 61326-3-1 |
| Lub cim tiv thaiv kev tawg | [Ex ia Ga] IIC [Ex ia Da] ⅢC |
| Lub Koom Haum Muab Daim Ntawv Pov Thawj | CQST (Tuam Tshoj Lub Chaw Saib Xyuas Kev Zoo thiab Kev Ntsuas rau Cov Khoom Siv Hluav Taws Xob Tiv Thaiv Kev Tawg) |
| Chaw Nres Tsheb 1-2, 3-4 | Um: 250V AC/DC Uo=28V DC Io=93mA Po = 0.65W Co = 0.083μF Lo = 4.2mH |
| Cov Kev Cai ntawm qhov chaw teeb tsa | Nruab rau hauv thaj chaw muaj kev nyab xeeb, nws tuaj yeem txuas nrog cov cuab yeej siv kev nyab xeeb hauv thaj chaw muaj kev phom sij mus txog rau thaj tsam 0, IIC, thaj tsam 20, thiab IIIC |
| MTBF | Txog li 100000 teev |
Lus Cim: Lub hwj chim ntawm lub tsheb ciav hlau fais fab yog ib qho kev xaiv ua haujlwm. Cov neeg siv yuav tsum tau qhia kom meej hom kev muab hluav taws xob thaum koj xaj khoom. Thov saib daim ntawv txuas nyob rau nplooj ntawv 89.
