PR293 Urukurikirane rwa Nanovolt Microhm Thermometero

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.
