PR293 Taxanaha Nanovolt Microhm Heerkulbeegga
Xallinta saxda ah ee saxda ah ee 7 1/2
Isku-dhafan thermocouple CJ
Kanaallo cabbiro badan
Heerkulbeegyada PR291 taxane microhm iyo PR293 taxane nanovolt microhm heerkulbeegyada waa aalado cabbiraad sax ah oo si gaar ah loogu talagalay cabbirka heerkulka.Waxay ku habboon yihiin hawlgallo badan, sida cabbiraadda xogta heerkulka dareeraha heerkulka ama xogta korantada, tijaabada isku-duubnida heerkulka ee foornooyinka cabbirka ama qubayska, iyo helitaanka calaamadaha heerkulka iyo duubista kanaalada badan.
Iyada oo xallinta cabbirku ka fiican tahay 7 1/2, marka la barbar dhigo multimeter-ka saxda ah ee saxda ah ee guud ee saxda ah, kaas oo si weyn loogu isticmaalay mitirka heerkulka muddo dheer, waxaa jira naqshado badan oo la hagaajiyay marka loo eego baaxadda, shaqada, saxnaanta, iyo fudaydka isticmaalka si looga dhigo habka cabirida heerkulka mid sax ah, ku haboon oo dhakhso badan.
Astaamaha
- Dareenka cabbirka 10nV/10μΩ
Naqshadaynta horumarsan ee cod-weyneeye dhawaqa aadka u hooseeya iyo moduleka sahayda korantada ee hooseeya waxay si weyn u yaraynaysaa qaylada akhriska ee loop-ka calaamada, taas oo kordhinaysa dareenka akhriska ee 10nV/10uΩ, oo si wax ku ool ah u kordhinaysa tirooyinka soo bandhigida wax ku oolka ah inta lagu jiro cabirka heerkulka.
- Xasilooni sanadeed heer sare ah
PR291/PR293 heerkulbeegyo taxane ah, oo qaadanaya mabda'a cabbiraadda saamiga iyo iska caabiyeyaasha heerka- tixraaceed ee ku dhex jira, waxay leeyihiin isku-xidhnaan heerkul aad u hooseeya iyo xasillooni sannadeed aad u wanaagsan.Iyadoo aan la aqbalin shaqada tixraaca heerkulka joogtada ah, xasiloonida sanadlaha ah ee taxanaha oo dhan ayaa weli si weyn uga fiicnaan kara 7 1/2 multimeter-ka dhijitaalka ah ee inta badan la isticmaalo.
- Isku dhafka kanaalka badan ee sanqadha hoose
Marka lagu daro kanaalka hore, waxaa jira 2 ama 5 qaybood oo madax-bannaan oo ah terminal shaqo oo dhammaystiran oo lagu dhex daray guddiga dambe iyadoo loo eegayo moodooyinka kala duwan ee heerkulbeegyada taxanaha PR291/PR293.Kanaal kastaa wuxuu si madax-bannaan u dejin karaa nooca calaamadda tijaabada, wuxuuna leeyahay is-waafajin aad u sarreeya oo u dhexeeya kanaalada, sidaas darteed helitaanka xogta channel-ka badan ayaa la samayn karaa iyada oo aan wax shidmo dibadeed ah lahayn.Intaa waxaa dheer, naqshadda sanqadha hoose waxay hubisaa in calaamadaha ku xiran kanaalada aysan keeni doonin buuqa akhriska dheeraadka ah.
- Magdhawga saxda ah ee CJ
Deganaanshaha iyo saxnaanta heerkulka CJ ayaa door muhiim ah ka ciyaara cabbiraadda heerkulbeegyada saxda ah ee saxda ah.Mitirrada dhijitaalka ah ee sida caadiga ah loo isticmaalo waxay u baahan yihiin in lagu daro qalabka magdhowga CJ ee gaarka ah ee cabbiraadda heerkulbeegga.Qaybta magdhawga saxda ah ee saxda ah ee CJ ee u heellan ayaa lagu dhex daray heerkulbeegyada taxanaha PR293, marka qaladka CJ ee kanaalka la isticmaalay ee ka fiican 0.15 ℃ iyada oo aan lahayn meelo kale waa la xaqiijin karaa.
- Heerkul qani ah ayaa shaqeeya
PR291/PR293 heerkulbeegyada taxanaha ah waa qalab tijaabo ah oo gaar ah oo loogu talagalay warshadaha cabbirka heerkulka.Waxa jira saddex nooc oo shaqo oo iibsi ah, hal-channel-ka-raadinta, iyo cabbiraadda kala duwanaanshaha heerkulka, kuwaas oo habka cabbiraadda kala duwanaanshiyaha heerkulka ay lafaguri karto isku-duubnaanta heerkulka dhammaan noocyada qalabka heerkulka joogtada ah.
Marka la barbar dhigo multimeter-ka dhijitaalka ah ee dhaqameed, kala duwanaansho 30mV ah oo si gaar ah loogu cabbirayo heerkulbeegyada nooca S-ka ah iyo 400Ω cabbirka PT100 caabbinta platinum ayaa lagu daray.Iyo barnaamijyada beddelka ku dhex jira ee dareemayaasha heerkulka kala duwan, dareemayaasha kala duwan (sida heerkulbeegyada caadiga ah, heerkulbeegyada caabbinta platinum caadiga ah, heerkulbeegyada caabbinta platinum ee warshadaha iyo heerkulbeegyada shaqeeya) waa lagu taageeri karaa, xogta shahaadada ama xogta sixitaanka ayaa loo tixraaci karaa raadinta. heerkulka natiijada baaritaanka.
- Shaqada falanqaynta xogta
Marka lagu daro xogta imtixaanada kala duwan, qalooca iyo kaydinta xogta ayaa la soo bandhigi karaa, xogta waqtiga-dhabta ah ugu badnaan / ugu yar / celceliska qiimaha, noocyada kala duwan ee xogta xasiloonida heerkulka ayaa la xisaabin karaa, iyo xogta ugu badan iyo tan ugu yar ayaa la calaamadayn karaa si loo fududeeyo falanqaynta xogta dareenka leh. goobta imtixaanka.
- Naqshadaynta la qaadi karo
Mitirrada dhijitaalka ah ee saxda ah ee sida caadiga ah lagu isticmaalo shaybaadhada ayaa ah kuwo waaweyn oo aan la qaadi karin.Taas bedelkeeda, heerkulbeegyada taxanaha ah ee PR291/PR293 ayaa ka yar mugga iyo miisaanka, kaas oo ku habboon tijaabada heerkul sare ee degaannada goobta.Intaa waxaa dheer, naqshadeynta baytariga lithium ee awoodda weyn ku dhex jira ayaa sidoo kale ka dhigaya habka hawlgalka mid sahlan.
