Tirohanga Whānui
Ka taea e te ārai haumaru wehewehe tāuru thermocouple te wehe me te huri i ngā tohu thermocouple (TC) i roto i ngā wāhi morearea ki ngā tohu iahiko 4-20mA, ka tukuna atu ki te rohe haumaru. He utu hononga makariri kei roto i tēnei ārai haumaru, ā, ka taea te whirihora ma te mohio. Ka taea te whakarite i te whānuitanga tuturu o te thermocouple mā te pūmanawa rorohiko. Kei a ia ngā mahi whakaoho whati waea me te whakaoho i waho o te whānuitanga. Me whai pūtake hiko motuhake tēnei hua, me te pūtake hiko motuhake, te tāuru, me ngā pito putanga. Ko te "*" te momo tāuru o te thermocouple, ā, ko te tauira motuhake e tohuhia ana e te waehere (tirohia "Te Momo Tohu Tāuru me te Ripanga Awhe" mō ētahi atu taipitopito).
Ngā momo tohu tāuru me te whānuitanga ine
| Waehere | Tauira TC | Awhe ine | Te whānuitanga iti rawa | Te tika o te tahuritanga |
| 1 | K | -200~1370℃ | 50℃ | 0.5℃/0.1% |
| 2 | S | -50~1760℃ | 500℃ | 1.5℃/0.1% |
| 3 | Ā, | -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% |
Tauira: ina he rua ngā tāuru me te takirua-K, ko te awhe pāmahana he 0~1200℃, ko ngā putanga e rua he 4~20mA, ko te pūtake hiko he 20~35VDC, ko te tauira me PHD-22TT-1111 (0~1200℃).
Ka taea e te rorohiko te whakatakoto i te awhe ine ki te awhe kua tohua 0~1200℃.
