Isishwankathelo
Umqobo wokhuseleko wokufakwa kwe-thermocouple ungahlukanisa kwaye uguqule imiqondiso ye-thermocouple (TC) kwiindawo ezinobungozi zibe yimiqondiso yangoku ye-4-20mA, kwaye uyikhuphele kwindawo yokhuseleko. Lo mqobo wokhuseleko une-cold junction cold compensation eyakhelwe ngaphakathi kwaye inokulungiswa ngobuchule. Uluhlu lokwenyani lwe-thermocouple lunokubekwa ngesoftware yekhompyutha. Inemisebenzi ye-wire breakage alarm kunye ne-out of range alarm. Le mveliso ifuna umbane ozimeleyo, kunye nombane ohlukeneyo, i-input, kunye ne-output terminals. "*" imele uhlobo lokufaka lwe-thermocouple, kwaye imodeli ethile imelwe yikhowudi (jonga "Uhlobo lweSignali yoNgeniso kunye neTheyibhile yoLuhlu" ukuze ufumane iinkcukacha).
Iintlobo zesignali yokufaka kunye noluhlu lokulinganisa
| Ikhowudi | Imodeli ye-TC | Uluhlu lokulinganisa | Uluhlu oluncinci | Ukuchaneka kokuguqulwa |
| 1 | K | -200~1370℃ | 50℃ | 0.5℃/0.1% |
| 2 | S | -50~1760℃ | 500℃ | 1.5℃/0.1% |
| 3 | KWAYE | -140~1000℃ | 50℃ | 0.5℃/0.1% |
| 4 | J | -160~1200℃ | 50℃ | 0.5℃/0.1% |
| 5 | B | 250~1800℃ | 500℃ | 1.5℃/0.1% |
| 6 | T | -200~400℃ | 50℃ | 0.5℃/0.1% |
| 7 | R | -50~1760℃ | 500℃ | 1.5℃/0.1% |
| 8 | N | -200~1300℃ | 50℃ | 0.5℃/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.
