I-PR293 Series Nanovolt Microhm Thermometer (2)

Ama-thermometer e-PR291 series microhm kanye nama-thermometer e-PR293 series nanovolt microhm ayizinto zokulinganisa ezinembe kakhulu ezenzelwe ngokukhethekile ukumetrology yokushisa. Afanele imisebenzi eminingi, njengokulinganisa idatha yokushisa yenzwa yokushisa noma idatha kagesi, ukuhlolwa kokufana kokushisa kwama-calibration furnaces noma amabhati, kanye nokutholwa kwesignali yokushisa nokuqoshwa kweziteshi eziningi.

Njengoba isixazululo sokulinganisa singcono kune-7 1/2, uma siqhathaniswa nama-multimeter edijithali ajwayelekile anembayo kakhulu, asetshenziswe kabanzi ekulinganisweni kwezinga lokushisa isikhathi eside, kunemiklamo eminingi elungiselelwe ngokwebanga, umsebenzi, ukunemba, kanye nokulula kokusetshenziswa ukwenza inqubo yokulinganisa izinga lokushisa inembe kakhudlwana, ilula futhi isheshe.

Izici

Ukuzwela kokulinganisa kwe-10nV / 10μΩ

Umklamo ophumelelayo we-amplifier yomsindo ophansi kakhulu kanye nemoduli yokunikezwa kwamandla e-ripple ephansi kunciphisa kakhulu umsindo wokufunda we-loop yesiginali, ngaleyo ndlela kwandisa ukuzwela kokufunda ku-10nV/10uΩ, futhi kwandisa ngempumelelo izinombolo zokubonisa ezisebenzayo ngesikhathi sokulinganisa izinga lokushisa.

Ukuqina okuhle kakhulu kwaminyaka yonke

Ama-thermometer ochungechunge lwe-PR291/PR293, asebenzisa isimiso sokulinganisa isilinganiso kanye nama-resistor ajwayelekile asezingeni lereferensi akhelwe ngaphakathi, ane-coefficient yokushisa ephansi kakhulu kanye nokuqina okuhle kakhulu konyaka. Ngaphandle kokusebenzisa umsebenzi wokubhekisela kokushisa okuhambisanayo, ukuzinza konyaka kochungechunge lonke kusengaba ngcono kakhulu kune-multimeter yedijithali engu-7 1/2 esetshenziswa njalo.

Isikena somsindo ophansi esineziteshi eziningi esihlanganisiwe

Ngaphezu kwesiteshi sangaphambili, kunezisethi ezimbili noma ezi-5 ezizimele zama-terminals okuhlola asebenza ngokugcwele ahlanganiswe kuphaneli yangemuva ngokusho kwamamodeli ahlukene kuma-thermometer ochungechunge lwe-PR291/PR293. Isiteshi ngasinye singasetha ngokuzimela uhlobo lwesignali yokuhlola, futhi sinokuvumelana okuphezulu kakhulu phakathi kweziteshi, ngakho-ke ukutholwa kwedatha yeziteshi eziningi kungenziwa ngaphandle kokushintsha kwangaphandle. Ngaphezu kwalokho, ukwakheka komsindo ophansi kuqinisekisa ukuthi izimpawu ezixhunywe ngeziteshi ngeke zilethe umsindo wokufunda owengeziwe.

Isinxephezelo se-CJ esinembile kakhulu

Ukuqina nokunemba kokushisa kwe-CJ kudlala indima ebalulekile ekulinganisweni kwama-thermocouple anembe kakhulu. Amamitha edijithali anembe kakhulu asetshenziswa njalo adinga ukuhlanganiswa nemishini ekhethekile yesinxephezelo se-CJ yokulinganisa i-thermocouple. Imodyuli yesinxephezelo se-CJ enembe kakhulu ezinikele ihlanganiswe kuma-thermometer ochungechunge lwe-PR293, ngakho-ke iphutha le-CJ lesiteshi esisetshenzisiwe elingaphezu kuka-0.15℃ ngaphandle kwezinye izinto ezisetshenziswayo lingabonakala.

Imisebenzi yokulinganisa izinga lokushisa elicebile

Ama-thermometer ochungechunge lwe-PR291/PR293 ayithuluzi lokuhlola elikhethekile elenzelwe imboni yokumetroloji yokushisa. Kunezindlela ezintathu zokusebenza zokuthola, ukulandelela kwesiteshi esisodwa, kanye nokulinganisa umehluko wokushisa, phakathi kwazo imodi yokulinganisa umehluko wokushisa ingahlaziya ukufana kokushisa kwazo zonke izinhlobo zemishini yokushisa engaguquki.

Uma kuqhathaniswa ne-multimeter yedijithali yendabuko, kunezelwa ububanzi obungu-30mV ngqo bokulinganisa ama-thermocouple ohlobo lwe-S kanye nobubanzi obungu-400Ω bokulinganisa ukumelana kweplatinum ye-PT100. Futhi ngezinhlelo zokuguqula ezakhelwe ngaphakathi zezinzwa ezahlukene zokushisa, izinzwa ezahlukahlukene (njenge-thermocouple ejwayelekile, ama-thermometers ajwayelekile okumelana neplatinum, ama-thermometers okumelana neplatinum yezimboni kanye nama-thermocouple asebenzayo) zingasekelwa, futhi idatha yesitifiketi noma idatha yokulungisa ingabhekiselwa ekulandeleni izinga lokushisa lemiphumela yokuhlolwa.

Umsebenzi wokuhlaziya idatha

Ngaphezu kwedatha yokuhlola ehlukahlukene, ama-curve kanye nesitoreji sedatha kungaboniswa, inani ledatha yesikhathi sangempela eliphakeme/eliphansi/elimaphakathi, idatha ehlukahlukene yokuzinza kwezinga lokushisa ingabalwa, kanye nedatha ephezulu nephansi ingaphawulwa ukuze kube lula ukuhlaziywa kwedatha okunembile endaweni yokuhlola.

Idizayini ephathekayo

Amamitha edijithali anembile kakhulu asetshenziswa kakhulu emalabhorethri ngokuvamile makhulu futhi awaphatheki kalula. Ngokuphambene nalokho, ama-thermometer ochungechunge lwe-PR291/PR293 ancane ngomthamo nangesisindo, okuyinto elula ekuhlolweni kwezinga eliphezulu lokushisa ezindaweni ezahlukahlukene endaweni. Ngaphezu kwalokho, ukwakheka kwebhethri le-lithium elikhulu elakhelwe ngaphakathi kwenza inqubo yokusebenza ibe lula.
