Isishwankathelo
Umqobo wokhuseleko wokufakwa kwe-RTD ungaguqula imiqondiso emibini okanye emithathu ye-thermistor ye-wire (RTD) kwiindawo ezinobungozi ibe yimiqondiso yangoku ye-4-20mA kwaye uyikhuphele kwindawo yokhuseleko. Ingacwangciswa ngobuchule, kwaye uluhlu lokwenyani lokumelana nobushushu lunokubekwa ngesoftware yekhompyutha. Inemisebenzi ye-alamu yokuqhekeka kwentambo kunye ne-alamu engaphandle komgangatho.
Le mveliso ifuna umbane ozimeleyo, kunye nombane ohlukeneyo, i-input, kunye nee-output terminals.
"*" imele uhlobo lokufaka lwe-thermistor, kwaye imodeli ethile imelwe yikhowudi (jonga "Uhlobo lweSignali yokungenisa kunye neTheyibhile yoLuhlu" ukuze ufumane iinkcukacha).
Iintlobo zesignali yokufaka kunye noluhlu lokulinganisa
| Ikhowudi | Imodeli ye-RTD | Uluhlu lokulinganisa | Uluhlu oluncinci | Ukuchaneka kokuguqulwa |
| 1 | G53 | -50~150℃ | 20℃ | 0.2℃/0.1% |
| 2 | I-Cu50 | -50~150℃ | 20℃ | 0.2℃/0.1% |
| 4 | I-Pt100 | -200~850℃ | 20℃ | 0.2℃/0.1% |
| 6 | I-Pt1000 | -200~850℃ | 20℃ | 0.2℃/0.1% |
| 7 | I-Ni1000 | -60~250℃ | 20℃ | 0.2℃/0.1% |
Umzekelo: xa igalelo li-input ezimbini ezine-K-couple, uluhlu lobushushu yi-0 ~ 1200℃, iziphumo ezi-2 yi-4 ~ 20mA, umbane yi-20 ~ 35VDC, ngoko ke imodeli kufuneka ibe yi-PHD-22TT-1111 (0 ~ 1200℃).
Uluhlu lokulinganisa lunokubekwa kuluhlu oluchaziweyo lwe-0 ~ 1200℃ ngekhompyutha.
