Huinga Pūoko Pāmahana Ātete (RTD)
Whakaahuatanga Hua
He pūoko pāmahana tino tika te huihuinga RTD. Ko tōna wāhanga pūoko matua he mea hanga i ngā konganuku tino parakore pērā i te konukawata (Pt) me te parahi (Cu). He tino tika te RTD konukawata me te whānuitanga o te pāmahana, engari he nui ake te utu, ā, he pai mō ngā tono ine tika me te pāmahana teitei. He tino pai te raina o ngā RTD parahi, ā, he iti ake te ōhanga, engari he whaiti ake te whānuitanga o te ine (-50°C ki te +150°C).
Ko te huihuinga RTD kua huihuia he mea hanga mai i tētahi waeine pūoko (waea konukawata, waea parahi rānei), he taura hononga, he ngongo tiaki, me tētahi pane hononga. Ko ngā momo matua ko ngā huihuinga RTD konukawata me ngā huihuinga RTD parahi.
Te Mātāpono Mahi o ngā RTD
Ka ine te RTD (Resistance Temperature Detector) i te pāmahana mā te whakamahi i te āhuatanga e rerekē ai te ātete hiko o te kaiārahi whakarewa me te pāmahana. Ina rerekē te pāmahana, ka whakaatu te uara ātete i tētahi whanaungatanga mahi tino rārangi ki te pāmahana. Mā te ine tika i tēnei ātete, ka taea te whakatau tika i te uara pāmahana e rite ana. Kāore i rite ki ngā thermocouples, kāore ngā RTD e hiahia ki te utu hononga makariri. Ka tukuna e rātou he putanga tohu pumau me te tika teitei, he mea pai mō ngā ine i roto i ngā awhe pāmahana iti ki te waenga.
Ngā Āhuatanga o ngā RTD
• Hanganga pakari me te kaha ā-mīhini teitei
• Te tāutanga ngāwari me te tiaki ngāwari
• Te tika o te ine me te pumau pai rawa atu
• Putanga tohu pumau me te kaha ārai-whakararuraru kaha
Ngā tono o ngā RTD
• Ahumahi Hiko:Te ine i te pāmahana i roto i ngā kohua tipu hiko, ngā paipa mamaoa, me ngā pūnaha whakaputa hau o te tāpine hiko.
• Ahumahi Pētara:Te aroturuki i te pāmahana o ngā tauhohenga, ngā oumu pakaru, ngā paipa, me ngā tāke rokiroki.
• Ahumahi Whakarewa:Te whakahaere pāmahana i roto i ngā oumu pupuhi, ngā oumu pupuhi wera, me ngā raina whakaputa hurihuri maitai.
• Ngā Taputapu Mīhini:Te ārai i te wera rawa mō ngā miihini, ngā peera, ngā pouaka miihini, me ētahi atu.
• HVAC (Whakamahana, Whakahauora, me te Āhuarangi):Te ine i te pāmahana wai me te hau i roto i ngā pūnaha hauhautanga pokapū.
• Ngā Taiwhanga me te Rangahau Pūtaiao:Ngā tono e hiahia ana ki te ine pāmahana tino tika, tino pumau hoki.
