Tirohanga Whānui
Ka taea e te ārai haumaru wehewehe whakauru RTD te huri i ngā tohu whakamahana waea e rua, waea e toru rānei (RTD) i roto i ngā wāhi morearea hei tohu iahiko 4-20mA, ka tukuna atu ki te rohe haumaru. Ka taea te whirihora ma te mohio, ā, ka taea te whakarite i te whānuitanga tuturu o te ātete wera mā te pūmanawa rorohiko. He mahi kei a ia hei whakaoho whati waea me te whakaoho i waho o te awhe.
Me whai pūtake hiko motuhake tēnei hua, me ngā pūtake hiko motuhake, ngā pūwāhi tāuru, me ngā pūwāhi whakaputa.
Ko te "*" te momo tāuru o te thermistor, ā, ko te tauira motuhake e tohuhia ana e tētahi waehere (tirohia "Ripanga Momo Tohu Tāuru me te Awhe" mō ētahi atu kōrero).
Ngā momo tohu tāuru me te whānuitanga ine
| Waehere | Tauira RTD | Awhe ine | Te whānuitanga iti rawa | Te tika o te tahuritanga |
| 1 | G53 | -50~150℃ | 20℃ | 0.2℃/0.1% |
| 2 | Cu50 | -50~150℃ | 20℃ | 0.2℃/0.1% |
| 4 | Pt100 | -200~850℃ | 20℃ | 0.2℃/0.1% |
| 6 | Pt1000 | -200~850℃ | 20℃ | 0.2℃/0.1% |
| 7 | Ni1000 | -60~250℃ | 20℃ | 0.2℃/0.1% |
Tauira: Ārai haumaru motuhake Pt100 tāuru, awhe pāmahana 0~400℃, e rua ngā putanga me te 4~20mA, ko te pūtake hiko he 20~35VDC. Ko te tauira ko PHD-22TZ-4141(0~400℃), ka taea te whakarite i te awhe ine ki te awhe kua tohua o te 0~400℃ mā te rorohiko.
