ʻO ke kūpaʻa Platinum, ʻike ʻia hoʻi he platinum thermal resistance, e hoʻololi ʻia kona waiwai kūʻē me ka mahana. A e hoʻonui pinepine ʻia ka waiwai kūʻē o ka pale platinum me ka piʻi ʻana o ka mahana.
Hiki ke hoʻokaʻawale ʻia ke kūpaʻa Platinum i nā huahana PT100 a me PT1000, ʻo PT100 ke ʻano o kona kūpaʻa ʻana ma 0 ℃ he 100 ohms, ʻo PT1000 ke ʻano o kona kūʻē ʻana ma 0 ℃ he 1000 ohms.
Loaʻa i ka Platinum resistance nā mea maikaʻi o ka vibration resistance, maikaʻi kūpaʻa, kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe ke kū'ē, a me nā mea'ē aʻe.
ʻO PT100 a i ʻole PT1000 nā ʻike wela he mau mea maʻamau i ka ʻoihana kaʻina. No ka mea ʻelua mau mea ʻike RTD, ʻo ka abbreviation RTD ke kū nei no ka "mea ʻike wela pale". No laila, he meaʻike wela kahi e hilinaʻi ai ke kū'ē i ka mahana; Ke hoʻololi ka mahana, e loli pū ke kū'ē o ka meaʻike. No laila, ma ke ana ʻana i ke kūʻē ʻana o ka sensor RTD, hiki iā ʻoe ke hoʻohana i ka sensor RTD e ana i ka mahana.
Hana ʻia nā mea ʻike RTD me ka platinum, keleawe, nickel alloys a i ʻole nā mea metala like ʻole, a ʻo PT100 kekahi o nā mea ʻike maʻamau. ʻO Platinum ka mea maʻamau no nā mea ʻike RTD. Loaʻa i ka Platinum kahi pilina kūpaʻa kūpaʻa, hiki ke hana hou a me ka laina. Ua kapa ʻia nā mea ʻike RTD i hana ʻia me ka platinum PRTS, a i ʻole "nā thermometers resistance platinum." ʻO ka sensor PRT maʻamau i hoʻohana ʻia i ka ʻoihana kaʻina hana ʻo ia ka sensor PT100. ʻO ka helu "100" ma ka inoa e hōʻike ana i kahi kū'ē o 100 ohms ma 0 ° C (32 ° F). ʻOi aku ma ia hope aku. ʻOiai ʻo PT100 ka mea maʻamau platinum RTD / PRT sensor, aia kekahi mau mea ʻē aʻe, e like me PT25, PT50, PT200, PT500, a me PT1000. ʻO ka ʻokoʻa nui ma waena o kēia mau mea ʻike, ʻo ia ka maʻalahi o ka manaʻo: ʻo ia ka maʻalahi o ka manaʻo. No ka laʻana, he 1000 ohm ke kūʻē ʻana o ka sensor PT1000 ma 0 ° C He mea nui hoʻi e hoʻomaopopo i ke koena wela no ka mea e pili ana i ka pale ʻana i nā mahana ʻē aʻe inā he PT1000 (385), ʻo ia ka mea he 0.00385 ° C ka mea maʻamau 385.
ʻO ka ʻokoʻa ma waena o PT1000 a me PT100 Resistors penei:
1. ʻOkoʻa ka pololei: ʻOi aku ka kiʻekiʻe o ka naʻau o ka PT1000 ma mua o ka PT100. Hoʻololi ka mahana o PT1000 i hoʻokahi degere, a piʻi a emi paha ka waiwai kū'ē ma kahi o 3.8 ohms. Hoʻololi ka mahana o PT100 i hoʻokahi degere, a piʻi a emi paha ka waiwai kū'ē ma kahi o 0.38 ohms, maopopo ʻo 3.8 ohms ʻoi aku ka maʻalahi ke ana pololei, no laila ʻoi aku ka kiʻekiʻe o ka pololei.
2. ʻOkoʻa ka laulā wela o ke ana.
He kūpono ʻo PT1000 no ke ana wela liʻiliʻi; He kūpono ka PT100 no ke ana ʻana i nā ana wela nui.
3. He okoa ke kumukuai. ʻOi aku ke kumukūʻai o PT1000 ma mua o ka PT100.
