PR293 Urukurikirane rwa Nanovolt Microhm Thermometero
Gukemura neza-7/2
Igizwe na thermocouple CJ indishyi
Imiyoboro myinshi yo gupima
PR291 ikurikirana ya microhm thermometero hamwe na PR293 ikurikirana ya nanovolt microhm thermometero nibikoresho byapimwe neza cyane byabugenewe byabugenewe kubipimo byubushyuhe.Birakwiriye mubikorwa byinshi, nko gupima amakuru yubushyuhe bwa sensor sensor cyangwa amakuru yumuriro wamashanyarazi, igipimo cyubushyuhe bwubushyuhe bwamatanura ya kalibrasi cyangwa ubwogero, hamwe no kubona ibimenyetso byubushyuhe no gufata amajwi menshi.
Hamwe no gukemura ibipimo byiza kurenza 7/2, ugereranije nubusanzwe rusange-yuzuye ya digitale ya digitale, yakoreshejwe cyane muri metero yubushyuhe igihe kirekire, hariho ibishushanyo mbonera byinshi byerekeranye nurwego, imikorere, ubunyangamugayo, no koroshya gukoresha kugirango ubushyuhe bwa Calibibasique burusheho kuba bwiza, bworoshye kandi bwihuse.
Ibiranga
- Ibipimo byo gupima 10nV / 10μΩ
Igishushanyo mbonera cya ultra-low urusaku rwinshi rwinshi hamwe na module ntoya itanga amashanyarazi bigabanya cyane urusaku rwo gusoma rwikimenyetso, bityo bikongerera ubushobozi bwo gusoma kuri 10nV / 10uΩ, kandi bikongerera neza imibare yerekana neza mugihe cyo gupima ubushyuhe.
- Umwaka mwiza cyane
PR291 / PR293 ikurikirana ya tometrometero, ikurikiza ihame ryo gupima ibipimo hamwe nububiko-bwerekanwe-urwego rusanzwe rurwanya, bifite coeffisente yubushyuhe buke cyane kandi ihamye yumwaka.Hatabayeho gukoresha ubushyuhe burigihe buhoraho, ibikorwa byumwaka byuruhererekane rwose birashobora kuba byiza cyane kurenza ibisanzwe bikoreshwa 7/2.
- Imiyoboro myinshi ihuriweho-ntoya-urusaku
Usibye umuyoboro w'imbere, hari ibice 2 cyangwa 5 byigenga byimikorere yuzuye yikizamini cyuzuye cyinjijwe kumwanya winyuma ukurikije moderi zitandukanye muri trometero ya PR291 / PR293.Buri muyoboro urashobora kwigenga gushiraho ubwoko bwibimenyetso byikizamini, kandi bifite ihame ryinshi cyane hagati yimiyoboro, kubwibyo kubona imiyoboro myinshi irashobora gukorwa nta guhinduranya hanze.Byongeye kandi, igishushanyo-cy-urusaku ruke rwemeza ko ibimenyetso bihujwe binyuze mu miyoboro bitazazana urusaku rwo gusoma.
- Indishyi zisobanutse neza CJ
Guhagarara no kumenya neza ubushyuhe bwa CJ bigira uruhare runini mugupima ibipimo bihanitse cyane.Ubusanzwe ikoreshwa rya metero nini cyane ya digitale igomba guhuzwa nibikoresho byihariye bya CJ byindishyi zo gupima thermocouple.Module yihariye-yuzuye ya CJ indishyi yinjijwe muri seriveri ya PR293 ya termometero, bityo ikosa rya CJ ryumuyoboro wakoreshejwe urenze 0.15 ℃ nta zindi periferi zishobora kugaragara.
- Imikorere ikungahaye cyane
PR291 / PR293 ikurikirana ya termometero nigikoresho cyihariye cyo gupima cyagenewe inganda zipima ubushyuhe.Hariho uburyo butatu bwo gukora bwo kugura, umuyoboro umwe ukurikirana, no gupima itandukaniro ryubushyuhe, muribwo buryo bwo gupima itandukaniro ryubushyuhe bushobora gusesengura uburinganire bwubushyuhe bwubwoko bwose bwibikoresho byubushyuhe buhoraho.
Ugereranije na multimeter gakondo ya digitale, 30mV murwego rwo gupima ubwoko bwa S-thermocouples na 400Ω intera yo gupima PT100 platine irwanya.Hamwe na porogaramu yubatswe ihinduranya ibyuma bitandukanye byubushyuhe, ibyuma bitandukanye (nka thermocouples isanzwe, ibipimo bya platine bisanzwe birwanya ibipimo bya termo, inganda za platine zirwanya inganda hamwe na thermocouples ikora) birashobora gushyigikirwa, kandi amakuru yicyemezo cyangwa amakuru yo gukosora arashobora kwerekanwa mugushakisha ubushyuhe bwibisubizo.
- Igikorwa cyo gusesengura amakuru
Usibye ibizamini bitandukanye byikizamini, umurongo hamwe nububiko bwamakuru birashobora kwerekanwa, amakuru nyayo-ntarengwa ntarengwa / ntarengwa / impuzandengo, imibare itandukanye yubushyuhe burashobora kubarwa, kandi amakuru ntarengwa kandi ntarengwa arashobora gushyirwaho kugirango byorohereze isesengura ryimbitse. kurubuga.
- Igishushanyo mbonera
Imetero-yukuri ya metero isanzwe ikoreshwa muri laboratoire ni nini kandi ntishobora kwerekanwa.Ibinyuranyo, PR291 / PR293 ikurikirana ya termometero ni ntoya mubunini n'uburemere, ibyo bikaba byoroshye mugupima ubushyuhe bwo murwego rwohejuru mubidukikije bitandukanye.Mubyongeyeho, igishushanyo mbonera cyubatswe na batiri nini ya litiro nayo yorohereza imikorere.
