Ukubuka konke
Isithiyo sokuphepha sokufakwa kwe-Thermocouple singahlukanisa futhi siguqule izimpawu ze-thermocouple (TC) ezindaweni eziyingozi zibe izimpawu zamanje ze-4-20mA, futhi sizikhiphele endaweni yokuphepha. Lesi sisithiyo sokuphepha sine-cold junction cold compensation eyakhelwe ngaphakathi futhi singalungiswa ngokuhlakanipha. Ububanzi bangempela be-thermocouple bungasethwa ngesofthiwe yekhompyutha. Inemisebenzi ye-alamu yokuphuka kwentambo kanye ne-alamu engaphandle kwebanga. Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okuneziphesheli zamandla ezihlukanisiwe, okokufaka, kanye nokukhipha. "*" imelela uhlobo lokufakwa kwe-thermocouple, futhi imodeli ethile imelelwa ikhodi (bheka "Uhlobo Lwesignali Yokufaka kanye Nethebula Lobubanzi" ukuthola imininingwane).
Izinhlobo zesignali yokufaka kanye nobubanzi bokulinganisa
| Ikhodi | Imodeli ye-TC | Ububanzi bokulinganisa | Ibanga elincane | Ukunemba kokuguqulwa |
| 1 | K | -200~1370℃ | 50℃ | 0.5℃/0.1% |
| 2 | S | -50~1760℃ | 500℃ | 1.5℃/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% |
Isibonelo: uma okokufaka kungukufaka okungu-2 nge-K-couple, ububanzi bokushisa bungu-0~1200℃, okuphuma okungu-2 kungu-4~20mA, ukunikezwa kwamandla kungu-20~35VDC, khona-ke imodeli kufanele ibe yi-PHD-22TT-1111 (0~1200℃).
Ibanga lokulinganisa lingabekwa kububanzi obucacisiwe be-0 ~ 1200℃ ngekhompyutha.
