ʻAha Kūkākūkā o ka Mea ʻIke Mahana Kū'ē (RTD)
Wehewehe Huahana
He mea ʻike wela kikoʻī ka ʻākoakoa RTD. Hana pinepine ʻia kona ʻāpana ʻike koʻikoʻi mai nā metala maʻemaʻe kiʻekiʻe e like me ka platinum (Pt) a i ʻole ke keleawe (Cu). Hāʻawi nā Platinum RTD i ka pololei kiʻekiʻe a me kahi ākea o ka mahana, akā ma ke kumukūʻai kiʻekiʻe aʻe, e kūpono ai no nā noi ana pololei a me ke ana wela kiʻekiʻe. Hāʻawi nā Copper RTDs i ka linearity maikaʻi loa a ʻoi aku ka hoʻokele waiwai, akā ʻoi aku ka haiki o ko lākou laulā ana (-50°C a i +150°C).
ʻO kahi ʻākoakoa RTD i hoʻākoakoa ʻia he ʻāpana ʻike (uea platinum a keleawe paha), nā alakaʻi pili, kahi paipu pale, a me ke poʻo pili. ʻO nā ʻano nui he mau ʻākoakoa platinum RTD a me nā ʻākoakoa keleawe RTD.
Kumumanaʻo Hana o nā RTD
Hoʻohana ka RTD (Resistance Temperature Detector) i ka mahana ma o ka hoʻohana ʻana i ka waiwai e loli ai ke kū'ē uila o kahi alakaʻi metala me ka mahana. Ke loli ka mahana, hōʻike ka waiwai kū'ē i kahi pilina hana linear kiʻekiʻe me ka mahana. Ma ke ana pololei ʻana i kēia kū'ē, hiki ke hoʻoholo pololei ʻia ka waiwai mahana e pili ana. ʻAʻole e like me nā thermocouples, ʻaʻole pono nā RTD i ka uku hoʻohui anu. Hāʻawi lākou i ka hoʻopuka hōʻailona paʻa a me ka pololei kiʻekiʻe, e kūpono ana iā lākou no nā ana ma nā pae mahana haʻahaʻa a waena.
Nā hiʻohiʻona o nā RTD
• Kūkulu paʻa me ka ikaika mechanical kiʻekiʻe
• Hoʻonohonoho maʻalahi a me ka mālama maʻalahi
• Pololei kiʻekiʻe o ke ana ʻana a me ke kūpaʻa maikaʻi loa
• Ka hoʻopuka hōʻailona paʻa me ka hiki ke pale aku i ke komo ʻana
Nā noi o nā RTD
• ʻOihana Mana:Ke ana ʻana o ka mahana i loko o nā paila o ka hale hana mana, nā paipu mahu, a me nā ʻōnaehana hoʻopau turbine.
• ʻOihana Petrochemical:Ka nānā ʻana i ka mahana o nā reactors, nā umu haki, nā pipeline, a me nā pahu mālama.
• ʻOihana Metallurgical:Ka mālama ʻana i ka mahana i loko o nā umu pahū, nā kapuahi pahū wela, a me nā laina hana ʻōwili kila.
• Nā Lako Hana Mīkini:Ka palekana no ka wela nui no nā ʻenekini, nā bearings, nā pahu pahu, a pēlā aku.
• HVAC (Hoʻomehana, hoʻoulu ea, a me ke ea hoʻoluʻu):Ke ana ʻana o ka mahana o ka wai a me ka ea ma nā ʻōnaehana ea waena.
• Nā Keʻena Hoʻokolohua a me ka Noiʻi ʻEpekema:Nā noi e pono ai ke ana wela pololei a paʻa loa.
