I-PR293 Uchungechunge lwe-Nanovolt Microhm Thermometer
Ukunemba okuphezulu kokulungiswa okungu-7 1/2
Isinxephezelo se-CJ esihlanganisiwe se-thermocouple
Iziteshi zokulinganisa eziningi
I-PR291 yochungechunge lwe-microhm thermometers kanye ne-PR293 yochungechunge lwe-nanovolt microhm thermometer angamathuluzi okulinganisa anembe kakhulu aklanyelwe ngokukhethekile i-metrology.Zifanele imisebenzi eminingi, njengokukalwa kwedatha yezinga lokushisa lenzwa yezinga lokushisa noma idatha kagesi, ukuhlolwa kokufana kwezinga lokushisa kwezithando zokulinganisa noma okugeza, nokutholwa kwesignali yezinga lokushisa nokurekhodwa kwamashaneli amaningi.
Ngokulungiswa kokulinganisa okungcono kuno-7 1/2, uma kuqhathaniswa nama-multimeters edijithali anembayo aphezulu, asetshenziswe kabanzi ku-metrology yokushisa isikhathi eside, kunemiklamo eminingi eyenziwe kahle ngokwebanga, umsebenzi, ukunemba, kanye nokusebenziseka kalula ukwenza inqubo yokulinganisa izinga lokushisa inembe kakhudlwana, ifaneleke futhi isheshe.
Izici
- Ukuzwela kokulinganisa kwe-10nV / 10μΩ
Idizayini ephumelelayo yesikhulisi somsindo esiphansi kakhulu kanye nemojula yokuphakelwa kwamandla aphansi wehlisa kakhulu umsindo wokufunda weluphu yesignali, ngaleyo ndlela kukhuphule ukuzwela kokufunda ku-10nV/10uΩ, futhi kukhuphule ngempumelelo amadijithi esibonisi asebenzayo phakathi nokukalwa kwezinga lokushisa.
- Ukuzinza okuhle konyaka
Amathemometha ochungechunge e-PR291/PR293, amukela isimiso sokulinganisa isilinganiso kanye nezimelana nezinga lereferensi eyakhelwe ngaphakathi, anesilinganiso sokushisa esiphansi kakhulu kanye nokuzinza okuhle kakhulu konyaka.Ngaphandle kokwamukela ukusebenza kwereferensi yokushisa engaguquki, ukuzinza konyaka walo lonke uchungechunge kusengaba ngcono kakhulu kune-multimeter yedijithali engu-7 1/2 evame ukusetshenziswa.
- Iskena esihlanganisiwe seziteshi eziningi esinomsindo ophansi
Ngaphezu kwesiteshi esingaphambili, kukhona amasethi azimele angu-2 noma angu-5 wamatheminali okuhlola asebenza ngokugcwele ahlanganiswe kuphaneli engemuva ngokuya ngamamodeli ahlukene kumathemometha ochungechunge lwe-PR291/PR293.Isiteshi ngasinye singasetha ngokuzimela uhlobo lwesignali yokuhlola, futhi sinokuvumelana okuphezulu kakhulu phakathi kwamashaneli, ngakho ukutholwa kwedatha yeziteshi eziningi kungenziwa ngaphandle kokushintsha kwangaphandle.Ngaphezu kwalokho, umklamo womsindo ophansi uqinisekisa ukuthi izimpawu ezixhunywe ngeziteshi ngeke zilethe umsindo wokufunda owengeziwe.
- Ukunemba okuphezulu kwesinxephezelo se-CJ
Ukuzinza nokunemba kwezinga lokushisa le-CJ kudlala indima ebalulekile esikalini sama-thermocouples anembe kakhulu.Amamitha edijithali asetshenziswa ngokunemba okuphezulu adinga ukuhlanganiswa nemishini ekhethekile yesinxephezelo ye-CJ yokulinganisa i-thermocouple.Imojula yesinxephezelo se-CJ enembayo Ephakeme kakhulu ihlanganiswe kumathemometha ochungechunge lwe-PR293, ukuze kubonakale iphutha le-CJ lesiteshi esisetshenzisiwe elingcono kuno-0.15℃ ngaphandle kwamanye ama-peripheral.
- Imisebenzi ye-metrology yokushisa enothile
Amathemometha ochungechunge lwe-PR291/PR293 ayithuluzi lokuhlola elikhethekile elenzelwe imboni ye-metrology.Kunezindlela ezintathu zokusebenza zokuthola, ukulandelela isiteshi esisodwa, kanye nokulinganisa umehluko wezinga lokushisa, phakathi kwazo imodi yokulinganisa umehluko wezinga lokushisa ingahlaziya ukufana kwezinga lokushisa kwazo zonke izinhlobo zemishini yokushisa engashintshi.
Uma kuqhathaniswa ne-multimeter yedijithali evamile, ibanga elingu-30mV eliqondiswe ngokukhethekile ukulinganisa ama-thermocouples ohlobo lwe-S kanye nobubanzi obungu-400Ω besilinganiso sokumelana ne-platinamu ye-PT100 kuyengezwa.Futhi ngezinhlelo zokuguqula ezakhelwe ngaphakathi zezinzwa ezihlukahlukene zokushisa, izinhlobonhlobo zezinzwa (njengama-thermocouples avamile, amathemometha avamile okumelana neplatinamu, amathemometha okumelana neplatinamu yezimboni nama-thermocouples asebenzayo) angasekelwa, futhi idatha yesitifiketi noma idatha yokulungisa ingabhekiselwa ekulandeleni. izinga lokushisa lemiphumela yokuhlolwa.
- Umsebenzi wokuhlaziya idatha
Ngaphezu kwedatha yokuhlola ehlukahlukene, amajika nokugcinwa kwedatha kungaboniswa, inani ledatha lesikhathi sangempela esiphezulu/ubuncane/isilinganiso esimaphakathi, idatha ehlukahlukene yokuzinza kwezinga lokushisa ingabalwa, futhi idatha ephezulu nencane ingamakwa ukuze kube lula ukuhlaziya idatha enembile. endaweni yokuhlola.
- Idizayini ephathekayo
Amamitha edijithali anembe kakhulu avame ukusetshenziswa ezindaweni zokucwaninga ngokuvamile abamakhulu futhi awaphatheki.Ngokuphambene, amathemometha ochungechunge lwe-PR291/PR293 mancane ngevolumu nesisindo, alungele ukuhlolwa kwezinga lokushisa eliphezulu ezindaweni ezihlukahlukene ezikusayithi.Ngaphezu kwalokho, ukuklanywa kwebhethri ye-lithium eyakhelwe ngaphakathi eyakhelwe ngaphakathi kwenza inqubo yokusebenza ibe lula.
