PHD-22HD-2121
Incamake
Inzitizi z'umutekano zitaruye kuruhande rwo gutahura: PHD-22HD-2121, kwinjiza no gusohora, kwinjiza kabiri na ibisohoka bibiri.
Inzitizi yitaruye irashobora gutandukanya no kohereza ikimenyetso cya 4 ~ 20mA cyangwa DC 4 ~ 20 mA ikimenyetso cyakozwe na transmitter ahantu hateye akaga ahantu hizewe. Iyo transmitter ari insinga ebyiri cyangwa insinga eshatu sisitemu, inzitizi yumutekano itanga imbaraga kubohereza.
Iki gicuruzwa gikeneye amashanyarazi yigenga.
Iki gicuruzwa gishyigikira ibimenyetso bya HART no gutabaza.
Ibisobanuro
| Tanga voltage | 20 ~ 35VDC, gukoresha ingufu |
| Gusohora amashanyarazi hamwe nimbaraga zitangwa | Iyo ibisohoka byumuzunguruko ari 20mA, voltage yatanzwe ni16V |
| Ikimenyetso cyo kwinjiza | Imiyoboro ibiri cyangwa insinga eshatu cyangwa ibimenyetso byubu (HART) |
| Ikimenyetso gisohoka | 4 ~ 20mA (HART) |
| Byemerewe gusohora imitwaro | 0 ~ 500Ω (birashoboka) |
| Ibisohoka neza | 0.1% FS (Agaciro gasanzwe: 0,05% FS) |
| Ubushyuhe bukabije | 0.005% FS / ℃ |
| Umubare winjiza nibisohoka | 2 kwinjiza 2 ibisubizo |
| Ibikoresho bikoreshwa mu murima | 2-wire, 3-wire transmitter hamwe nibimenyetso byubu, iki gicuruzwa kibereye ABB, Fisher, Rosemount, Honeywell 11, kimwe na 3351, EJA, SIEMENS nibindi bicuruzwa bifite ikoranabuhanga ritumizwa mu mahanga |
| Ubushyuhe | Ubushyuhe bwo gukora: -20 ℃ ~ + 60 ℃, ubushyuhe bwo kubika: -40 ℃ ~ + 80 ℃ |
| Ubushuhe bugereranije | 10% ~ 95% RH ntagahunda |
| Imbaraga zo gukumira | Hagati y'uruhande rwumutekano imbere n'uruhande rutagira umutekano (≥3000VAC / min); hagati yo gutanga amashanyarazi n'impande zidafite umutekano (≥1500VAC / min) |
| Kurwanya insulation | ≥100MΩ (hagati yinjiza / ibisohoka / amashanyarazi) |
| Ibipimo byo hanze | Umubyimba 15.8mm * ubugari 104.8mm * hejuru ya 116.1mm |
| Guhuza amashanyarazi | Ukurikije IEC 61326-1 (GB / T 18268), IEC 61326-3-1 |
| Ikimenyetso-giturika | [Exia Ga] IIC, [Exia Da] IIIC |
| Icyemezo cy'umutekano ukora | SIL2 ukurikije IEC 61508 EN 61511 |
| Urwego rwemeza | CQST (Ubushinwa Igenzura ry’Ubuziranenge n’ikigo cy’ibizamini byo guturika bikingira ibicuruzwa bikomoka ku mashanyarazi) |
| Ibipimo byemewe (hagati ya terefone 1-3) Ibipimo byemewe (hagati ya terefone 2-3,2-1) | Um = 250V Uo = 7.2V Io = - Po = - Co = 12μF Lo = - Um = 250V Uo = 28V Io = 93mA Po = 0,65W Co = 0.083μF Lo = 4.2mH |
| Ibisabwa kurubuga | Irashobora guhuzwa nibikoresho muri zone 0 hamwe na ⅡA, ⅡB, ⅡC gaze iteje akaga |
| MTBF | ≤100000h |
