He ātete wera konukawata te Pt1000, ā, ka rerekē tōna uara ātete i te huringa o te pāmahana. Ko te tau 1000 i muri i te "Pt" e tohu ana ko tōna uara ātete he 1000 ohms i te 0°C, ā, ko tōna uara ātete he tata ki te 1758.56 ohms i te 200°C. Ka piki haere te uara ātete o te PT1000 i te pikinga o te pāmahana. He ātete wera konukawata anō hoki te Pt100. Ko te tau 100 i muri i te "Pt" e tohu ana ko tōna uara ātete he 100 ohms i te 0°C, ā, ko tōna uara ātete he tata ki te 175.86 ohms i te 200°C. He ātete wera konukawata anō hoki te Pt500. Ko te tau 500 i muri i te "Pt" e tohu ana ko tōna uara ātete he 500 ohms i te 0°C, ā, ko tōna uara ātete he tata ki te 879.30 ohms i te 200°C.
I ēnei rā, ko te Pt1000 te mea e whakamahia nuitia ana mō te ine i te pāmahana i roto i ngā mita wera, i ngā karorimita rānei. Tuatahi, he nui ake te tau whakawātea Pt1000, ā, he nui ake te tika. Tuarua, he teitei ake te aukati whakauru o Pt1000, ā, ka taea te whakanui ake i te ngaohiko whakaoho, ā, ka pai ake te aro. Tuatoru, he pai te PT1000 mō te ine i ngā huringa pāmahana iti (ko te take he nui te huringa o te uara ātete ina huri te pāmahana mā te kotahi nekehanga, ā, ka taea e te ara iahiko e whai ake nei te kite ngāwari). Mō te whakamahinga, he watea ake hoki te Pt1000. I roto i ngā tono ahumahi, ko te tikanga, ka hurihia ngā tohu ātete o Pt100 me Pt500 hei tohu iahiko 4-20mA, kātahi ka tukatukahia ngā tohu. Heoi, ka ine tika a Pt1000 i te tohu ātete.
