Ividiyo yomkhiqizo
Imikhiqizo yochungechunge lwe-PR231 inezinkomba zokusebenza ezinhle kakhulu, imisebenzi eminingi ebonakalayo nesixhumi esibonakalayo esinamandla somuntu .Lolu chungechunge luhlanganisa amazinga amabili okunemba, u-0.01% no-0.02%.Isilinganiso nomthombo kuhlukaniswe ngokuphelele, ngaphezu kwemisebenzi evamile yesilinganisi esineziteshi ezimbili, sinomsebenzi wokulinganisa wenani lika-ρ kanye nezinga lokushisa elijwayelekile.Uhlobo oluthuthukisiwe luphinde lube nokuhlolwa kokuhluka kwezinga lokushisa kanye nomsebenzi wokulawula izinga lokushisa onembayo.Ihlangene ekwakhiweni kwayo, iyaphatheka, futhi ilungele ukusetshenziswa endaweni kanye nezaselabhorethri, okuyenza ibe yinketho yokuqala yokulinganisa izinga lokushisa.
Izici Zemikhiqizo
1.Isilinganiso somehluko wezinga lokushisa ngokunemba kuka-0.003 ° CIsilinganisi se-PR231A sikala umehluko wezinga lokushisa phakathi kwamaphoyinti amabili esikhaleni ngaphandle kwamanye amathuluzi.Uma umsebenzi usetshenziswa, amatheminali amane omsebenzi womthombo asetshenziswa njengamatheminali okulinganisa futhi inqubo yokutholwa kwedatha yomehluko wezinga lokushisa ingaqedwa phakathi kwamasekhondi angu-0.4, okuthuthukisa ngempumelelo ukunemba kwesilinganiso.Ukuzinza kungabuye kubalwe ngesikhathi sangempela phakathi nokuhlolwa
2.Isilinganiso sokushisa esijwayelekile
Ihlukile esilinganisweni esijwayelekile se-TC ne-RTD, ukukalwa kwezinga lokushisa okujwayelekile kungase kusebenzise inani lesitifiketi ukuze kulandeleke izinga lokushisa.Izimpawu zokufaka zihlanganisa:STC – > Uhlobo lwe-S, uhlobo luka-R, uhlobo lwe-B, uhlobo lwe-T.SPRT-> Rtp = 25Ω noma i-Rtp=100Ω.
3.Reference Junction Isinxephezelo
Izindlela zokunxephezela zenkombandlela yereferensi ye-PR231 yochungechunge lwe-calibrator zivumelana nezimo kakhulu futhi izindlela ezintathu ziyatholakala, okungezangaphakathi, ngaphandle, kanye nezifiso.Ukuhlangana kwereferensi yangaphandle kusebenzisa iBanga A Pt100, futhi ingafaka inani lesitifiketi sokulungiswa kwedatha yenkomba yenkomba.Uma isilinganisi sochungechunge lwe-PR231 sihlanganiswa nemojula yesinxephezelo sokulinganiswa kwezinga lokushisa kwe-PR1501, iphutha lesinxephezelo senkomba yenkomba elingaphansi kuka-0.07°C lingatholwa.
4.Precision umsebenzi wokulawula izinga lokushisa
Ngokusebenzisa umsebenzi wokulawula izinga lokushisa onembayo, ukulawulwa kwezinga lokushisa okuvaliwe kwe-loop yemishini yokushisa engaguquki kungenziwa esikhundleni sesilawuli se-PID esinembe kakhulu.Esimeni lapho okokusebenza kwezinga lokushisa okungashintshi kanye negridi kagesi kuyanelisa izimo, ukushintshashintsha kwezinga lokushisa kwemishini kungaba ngcono kuno-0.02°C/10min.
(ukugeza kwe-thermostatic).
5.ρukulinganisa inani
Isilinganisi sochungechunge lwe-PR231 singakala isici somsebenzi wesignali yesikwele sezikhathi ezithile futhi singasetshenziswa ukuze kuqinisekiswe futhi kulinganiswe amapharamitha e-PID okushisa okuhlukahlukene kwedijithali abonisa izilawuli zokukhipha isikhathi ngokulingana, futhi sihlangabezane nezimfuneko ze-JJG 617-1996 Ukulawulwa Kokuqinisekisa Kwezinga Lokushisa Ledijithali. Izinkomba Nabalawuli.
6.Isibali esishisayo
Isetshenziselwa ukufeza ukuguqulwa okuhlukahlukene phakathi kukagesi nezinga lokushisa.Ukuguqulwa kusekela ama-TC ahlukahlukene, ama-RTD nama-thermistors.
7.Izilungiselelo Zenani
Isilinganisi sochungechunge lwe-PR231 sinendlela yokusetha inani lokukhiphayo evumelana nezimo kakhulu futhi elula.Kungenzeka ukusetha ngokuqondile inani lokukhiphayo ngekhiphedi yezinombolo, noma ukukhulisa ukulungiselelwa kokukhuphuka ngokucindezela inkinobho yokuqondisa.Ngaphezu kwalokho, idivayisi inesinyathelo sesigaba esihlelekayo noma indlela yokusetha inani lemithambeka.
8.Umsebenzi wokukhipha isignali ye-Sinusoidal
Ukuqinisekisa/ukulinganisa kwabanye abagawuli benqubo, ikakhulukazi abaqopha imishini, ngokuvamile kuhilela ukuhlolwa kokusebenza.Kulesi simo, umsebenzisi angasebenzisa umsebenzi wokukhipha isignali ye-sinusoidal ukuze anikeze amasignali ethuluzi eliqinisekisiwe.
Ukuqinisekiswa/ukulinganisa kwamanye amarekhodi enqubo (ikakhulukazi amarekhoda emishini) ngokuvamile kuhilela ukusebenza kokuhlolwa.Ngalesi sikhathi, umsebenzi wokukhipha isignali ye-sinusoidal wedivayisi ungasetshenziswa ukuze ubonise imitha.
9.Umsebenzi wokungena kwedatha
Umsebenzi wokugawula ulondoloza idatha yokulinganisa neyokukhiphayo.Isilinganisi sochungechunge lwe-PR231 sinemisebenzi yokuphatha irekhodi enamandla.Kungadaleka izinombolo zedivayisi ezingafika kwezingu-32.Inombolo yedivayisi ngayinye inamakhasi okuloga angu-16.Ikhasi ngalinye lokungena liqukethe izinhlobo ezine zolwazi oluyisisekelo, okungukuthi isikhathi, inani elilinganiselwe, inani lokukhiphayo kanye nevelu yangokwezifiso.Ulwazi oluyisisekelo.Abasebenzisi bangakwazi ukucubungula idivayisi, ukususa irekhodi, njll. ngokwezidingo zabo.
