Thermocouples akakosha ekuyera tembiricha maturusi mumaindasitiri akasiyana. Pakati pemhando dzakasiyana-siyana, platinum-rhodium thermocouples inomira kunze kwekuita kwavo kwepamusoro-kupisa uye kunyatsoita. Ichi chinyorwa chichaongorora zvakadzama zveplatinamu-rhodium thermocouples, kusanganisira mashandisiro adzo, waya yakanakisa yethermocouple, uye kuumbwa kweS-type thermocouples.
Ndeapi marudzi eplatinamu-rhodium thermocouples?
Kune mhando nhatu huru dzeplatinamu-rhodium thermocouples: B-mhando, R-mhando, uye S-mhando. Aya ma thermocouples anozivikanwa nekugadzikana kwawo kwepamusoro-tembiricha uye anowanzoshandiswa mumashandisirwo anoda kuyerwa kwekushisa chaiko.
1. Rudzi rweB (Platinum 30% Rhodium / Platinum 6% Rhodium): Kupisa kwekushisa: 0 ° C kusvika 1700 ° C, Zvimiro: Rudzi rweB thermocouples rwakagadzikana zvikuru uye runogona kuyera kupisa kwakanyanya. Inowanzo shandiswa muhuni dzekupisa uye hovhoni.
2. Rudzi R (Platinum 13% Rhodium / Platinum): Temperature yakasiyana-siyana: -50 ° C kusvika 1600 ° C, Zvimiro: Rudzi R thermocouples rinorova kuenzana kwakanaka pakati pemari uye kushanda. Iwo anoshandiswa mune akasiyana siyana maindasitiri ekushandisa anosanganisira kugadzirwa kwegirazi uye kugadzira simbi.
3. Rudzi S (Platinum 10% Rhodium / Platinum): Kupisa kwekushisa: -50 ° C kusvika 1600 ° C, Zvimiro: Rudzi S thermocouples dzinozivikanwa nokuda kwekururama uye kugadzikana. Iwo anowanzo shandiswa mumarabhoritari uye mumaindasitiri uko kutarisisa tembiricha kwakakosha.
Ndeipi yakanakisa thermocouple waya?
Chinangwa chekutarisa kunaka kwechigadzirwa chiri mumhando yacho. Zvigadzirwa zvakasiyana zvine maitiro akasiyana emhando, uye mhando yeplatinamu-rhodium thermocouple waya inogona kutongwa kubva kune zvinotevera zvivakwa. Chekutanga, waya yeplatinamu-rhodium ine kugadzikana kwekushisa kwepamusoro uye inogona kumira zvakanyanya tembiricha isina kushatisa. Kugadzikana uku kunovimbisa kuyerwa kwetembiricha kwakaringana pamusoro petembiricha yakakura. Chechipiri, platinamu-rhodium thermocouples inopa chaiyo tembiricha kuyerwa, ichiita kuti ive yakanakira maapplication anoda kunyatsoita. Pamusoro pezvo, platinamu uye rhodium zvakare ine yakakwira corrosion kuramba, ichivimbisa hupenyu hwesevhisi uye kuvimbika kwewaya yethermocouple munzvimbo dzakaoma. Kusimba kweplatinamu-rhodium thermocouple waya kunoita kuti ive yakakodzera kushandiswa kwenguva refu mumaindasitiri ekushandisa, ichideredza kudiwa kwekudzokororwa kazhinji. Kana izvo zvinodikanwa zvekuyera kurongeka, kugadzikana, oxidation kuramba, nezvimwe zvakakwirira zvakanyanya, platinamu-rhodium thermocouple waya ndiyo yakanakisa sarudzo.
Chii chinoshandiswa neplatinamu thermocouple waya?
Platinum thermocouple wayachinhu chinokosha pakuvakwa kweplatinum-rhodium thermocouples. Hunhu hwayo hwakasiyana hunoita kuti platinamu-rhodium thermocouple waya ikwane kune dzakasiyana siyana dzekudziya kwepamusoro. Muindasitiri yemuchadenga, platinamu thermocouple waya inoshandiswa kuyera tembiricha yejeti injini uye zvimwe zvinopisa zvakanyanya. Kuyera kwakaringana tembiricha kwakakosha pakuchengetedza uye kuita kwemidziyo yemuchadenga. Platinamu thermocouple waya inoshandiswa muvira remaindasitiri kutarisa uye kudzora tembiricha yakakwira. Kugadzikana kwavo uye kurongeka kunovimbisa kuti choto chinoshanda mukati meiyo tembiricha inodiwa, nekudaro inovandudza kushanda uye kunaka kwechigadzirwa. Uye zvakare, iyo girazi yekugadzira maitiro inoda chaiyo tembiricha yekudzora, uye platinamu thermocouple waya inoshandiswa kutarisa tembiricha yevira regirazi kuti ive nechokwadi chekuenderana uye chemhando yepamusoro kugadzirwa kwegirazi. Mutsvagiridzo yesainzi, kuyerwa kwetembiricha kwakakosha pakuedza uye kuunganidza data. Platinum thermocouple waya inoshandiswa kuyera tembiricha mukuyedza kwakasiyana murabhoritari, ichipa data rakavimbika uye rakarurama.
Platinamu-rhodium thermocouples (kusanganisira mhando B, R, uye S) maturusi akakosha ekuyera nemazvo tembiricha mumashandisirwo ekupisa kwepamusoro. Pakusarudza iyo yakanakisa thermocouple waya, platinamu-rhodium thermocouples inowanzova sarudzo yekutanga nekuti inoita zvakanaka munzvimbo dzakaoma. Platinamu-rhodium thermocouples inoita basa rakakosha mumaindasitiri akasiyana, ichipa iko kurongeka uye kugadzikana kunodiwa kune yakakwirira-tembiricha application.
