Platinum kuramba, inozivikanwawo seplatinamu yekupisa kupikisa, kukosha kwayo kwekudzivirira kuchachinja nekupisa.Uye kukosha kwekupikisa kweplatinamu kuramba kunowedzera nguva dzose nekuwedzera kwekushisa.
Platinum resistance inogona kupatsanurwa kuita PT100 uye PT1000 series products, PT100 zvinoreva kuti resistance yayo pa0℃ is 100 ohms, PT1000 zvinoreva kuti resistance yayo pa0℃ i1000 ohms.
Platinum kuramba ine zvakanakira vibration resistance, kugadzikana kwakanaka, kusimba kwepamusoro, high pressure resistance, etc. Inoshandiswa zvakanyanya mukurapa, mota, indasitiri, kuverengera tembiricha, setiraiti, mamiriro ekunze, kuverengera kupikisa uye zvimwe zvakanyanyisa kupisa tembiricha midziyo.
PT100 kana PT1000 tembiricha sensors akajairika ma sensors muindasitiri yekuita.Sezvo ese ari maviri eRTD sensors, chidimbu RTD chinomiririra "resistance tembiricha detector".Nokudaro, inzwa yekushisa apo kushorwa kunoenderana nekupisa;Kana tembiricha ichichinja, kushorwa kwe sensor kuchachinjawo.Naizvozvo, nekuyera kuramba kweRTD sensor, unogona kushandisa iyo RTD sensor kuyera tembiricha.
RTD sensors inowanzogadzirwa neplatinum, mhangura, nickel alloys kana akasiyana-siyana esimbi oxides, uye PT100 imwe yeanonyanya kuzivikanwa ma sensors.Platinamu ndiyo inonyanya kuzivikanwa zvinhu zveRTD sensors.Platinum ine yakavimbika, inodzokororwa uye mutsara tembiricha kuramba hukama.RTD masensa akagadzirwa neplatinamu anonzi PRTS, kana "platinamu resistance thermometers."Iyo inonyanya kushandiswa PRT sensor muindasitiri yekugadzira ndiyo PT100 sensor.Nhamba "100" muzita inoratidza kuramba kwe100 ohms pa 0 ° C (32 ° F).Zvimwe pamusoro pazvo gare gare.Nepo PT100 iriyo inonyanya kuzivikanwa platinamu RTD/PRT sensor, kune mamwe akati wandei, akadai sePT25, PT50, PT200, PT500, uye PT1000.Musiyano mukuru pakati pezviyero izvi zviri nyore kufungidzira: uku ndiko kupikisa kwe sensor pa 0 ° C, iyo inotaurwa muzita.Semuenzaniso, iyo PT1000 sensor ine kuramba kwe1000 ohms pa0 ° C.Izvo zvakakoshawo kuti unzwisise tembiricha coefficient nekuti inokanganisa kuramba kune mamwe tembiricha.Kana iri PT1000 (385), zvinoreva kuti ine tembiricha inokwana 0.00385°C.Munyika yose, shanduro yakajairika ndeye 385. Kana iyo coefficient isina kutaurwa, inowanzoita 385.
Musiyano uripakati pePT1000 uye PT100 Resistors ndewekuti:
1. Kururama kwakasiyana: Kuita senitivity yePT1000 yakakwirira kudarika yePT100.Tembiricha yePT1000 inoshanduka nedhigirii rimwe chete, uye kukosha kwekupikisa kunowedzera kana kuderera ne3.8 ohms.Iyo tembiricha yePT100 inoshanduka nedhigirii rimwe chete, uye kukosha kwekudzivirira kunowedzera kana kuderera neanosvika 0.38 ohms, zviri pachena kuti 3.8 ohms iri nyore kuyera nemazvo, saka iko kurongeka kwakakwira zvakare.
2. Chiyero chekushisa kwechiyero chakasiyana.
PT1000 inokodzera diki siyana tembiricha kuyerwa;Iyo PT100 yakakodzera kuyera yakakura siyana tembiricha kuyerwa.
3. Mutengo wacho wakasiyana.Mutengo wePT1000 wakakwira kupfuura wePT100.
