Tirohanga
Ka taea e te arai haumaru whakamaarama te whakamaarama te wehe me te huri i nga tohu thermocouple (TC) i nga waahi morearea ki nga tohu o naianei 4-20mA, ka whakaputa ki te rohe haumaru. Ko tenei arai haumaru kua hanga-i roto i te kapeneheihana mutunga makariri, ka taea te whirihora. Ka taea te whakarite te awhe tuturu o te thermocouple ma te rorohiko rorohiko. Kei a ia nga mahi o te whakaoho whati waea me waho o te awhe whakaoho.Kei a ia nga mahi o te whakaoho momotu me te whakaoho i waho o te awhe.
Ko tenei hua e hiahia ana ki te tuku hiko motuhake, me te tuku hiko motuhake, te whakaurunga, me nga pito putanga.
"*" e tohu ana i te momo whakauru o te thermocouple, a ko te tauira motuhake e tohuhia ana e te waehere (tirohia "Momo Tohu Whakauru me te Ripanga Awhe" mo nga taipitopito).
Momo tohu whakauru me te awhe ine

| 8 | N | -200~1300 ℃ | 50 ℃ | 0.5℃/0.1% |
Tauira: ina he 2 whakaurunga te whakauru ki te K-rua, te awhe pāmahana ko 0 ~ 1200 ℃, 2 putanga 4 ~ 20mA, mana supply 20 ~ 35VDC, ka te tauira kia PHD-22TT-1111 (0 ~ 1200 ℃).
Ka taea te tautuhi i te awhe ine ki te awhe 0 ~ 1200 ℃ kua tohua e te rorohiko.
