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).
