Cummins tembiricha uye pressure sensor pressure alarm switch 4921479

Contactless

Zvinhu zvaro zvinonzwisisika hazvibatanidzine nechinhu chakayerwa, icho chinonziwo kwete-kubata tembiricha yekuyera mudziyo.Ichi chiridzwa chinogona kushandiswa kuyera tembiricha yepasi pezvinhu zvinofamba, tarisiro diki uye zvinhu zvine diki kupisa simba kana kukurumidza kuchinja tembiricha (inopfupika), uye inogona zvakare kushandiswa kuyera kugoverwa kwekushisa kwenzvimbo yekushisa.

Iyo inonyanya kushandiswa isiri-contact thermometer yakavakirwa pamutemo wekutanga weiyo blackbody radiation uye inonzi radiation thermometer.Radiation thermometry inosanganisira nzira yekupenya (ona optical pyrometer), nzira yemwaranzi (ona radiation pyrometer) uye colorimetric nzira (ona colorimetric thermometer).Mhando dzese dzeradiation thermometry nzira dzinogona chete kuyera inoenderana photometric tembiricha, radiation tembiricha kana colorimetric tembiricha.Chete tembiricha inoyerwa munhu mutema (chinhu chinotora mwaranzi yose asi isingaratidzi chiedza) ndiko kupisa chaiko.Kana iwe uchida kuyera tembiricha chaiyo yechinhu, unofanirwa kugadzirisa kubuda kwechinhu chepamusoro.Nekudaro, iyo yepasi emissivity yezvishandiso inotsamira kwete chete tembiricha uye wavelength, asiwo pamusoro pemamiriro, coating uye microstructure, saka zvakaoma kuyera nemazvo.Mukugadzira otomatiki, kazhinji zvinodikanwa kushandisa radiation thermometry kuyera kana kudzora tembiricha yepamusoro yezvimwe zvinhu, senge simbi strip rolling tembiricha, roll tembiricha, tembiricha yekubikira uye tembiricha yesimbi dzakasiyana dzakanyungudutswa muchoto chekunyungudutsa kana crucible.Muzviitiko izvi, zvakaoma kuyera kubuda kwechinhu pamusoro pechinhu.Kuyeresa otomatiki uye kutonga kwekushisa kwakasimba kwepasi, imwe ratidziro inogona kushandiswa kugadzira mhango yeblackbody ine nzvimbo yakayerwa.Simba rekuwedzera mwaranzi rinogona kuvandudza mwaranzi inoshanda uye inoshanda emission coefficient yeyakayerwa pamusoro.Uchishandisa iyo inoshanda emission coefficient, tembiricha yakayerwa inogadziriswa nechiridzwa, uye pakupedzisira tembiricha chaiyo yenzvimbo yakayerwa inogona kuwanikwa.Chionioni chinonyanyozivikanwa chionioni chehemispherical.Kupararira kwemwaranzi yenzvimbo yakayerwa padhuze nepakati pebhora inogona kuratidzwa kumashure nehemispherical girazi kuti igadzire yakawedzera mwaranzi, nekudaro ichivandudza emission coefficient, uko ε ndiko kuburitsa kwechinhu chepamusoro uye ρ ndiko kuratidza. chegirazi.Kana iri kuyerwa kwemwaranzi yekushisa chaiko kwegasi uye midhiya yemvura, nzira yekuisa chubhu inodzivirira kupisa kune imwe kudzika kuti iite mhango yeblackbody inogona kushandiswa.Iyo inobudirira emission coefficient ye cylindrical cavity mushure mekudziya kwekuenzanisa nepakati inowanikwa nekuverenga.Muyero ye otomatiki uye kutonga, kukosha uku kunogona kushandiswa kururamisa kuyerwa kwepasi tembiricha (kureva, tembiricha yepakati) uye kuwana tembiricha chaiyo yepakati.

Zvakanakira kwete-kusangana tembiricha kuyerwa:

Muganho wepamusoro wekuyera hauganhurwe nekushivirira kwekushisa kwezvinhu zvinonzwa tembiricha, saka hapana muganho kune yakanyanya kuyerwa tembiricha mumusimboti.Pakupisa kwepamusoro pamusoro pe1800 ℃, nzira yekuyera tembiricha isiri-yekubata ndiyo inonyanya kushandiswa.Nekuvandudzwa kwe tekinoroji ye infrared, kuyerwa kwekushisa kwemwaranzi kwakawedzera zvishoma nezvishoma kubva pachiedza chinooneka kuenda kuchiedza che infrared, uye yakashandiswa pazasi 700 ℃ kusvika kukamuri tembiricha ine yakakwirira resolution.
