Dab tsi yog cov haujlwm ntawm thermocouples
Muaj ntau dua 300 hom thermocouples uas nquag siv rau kev tsim khoom, cov uas 40-50 tau siv dav. Lub International Electrotechnical Commission tau pom zoo 8 hom thermocouples rau cov teb chaws thoob ntiaj teb raws li tus qauv thermocouples, thiab kuj tseem muaj 8 hom qauv thermocouples hauv Suav teb. Lawv yog: Platinum Rhodium 10 Platinum (division tooj S), Platinum Rhodium 13 Platinum (R), Platinum Rhodium 30 Platinum Rhodium 6 (B), Nickel Chromium Nickel Silicon (K), Nickel Chromium Constantan (E), Iron Constantan () , Copper Constantan (T), thiab Nickel Chromium Silicon Nickel Silicon (N). Hauv qab no yog cov lus qhia luv luv rau ntau lub thermocouples uas feem ntau siv: 1. Platinum Rhodium 10 Platinum Thermocouple 1. Composition: φ Ua los ntawm 0.5 hli ntshiab platinum hlau thiab platinum rhodium hlau nrog tib txoj kab uas hla, nrog rau kev faib tus lej S. (K-hom Thermoelectric)
Cov electrodes ntawm qhov ntsuas kub ntsuas thermocouples yog qhov tseem ceeb ntawm kev ntsuas qhov ntsuas qhov tseeb. Txhawm rau kom ntseeg tau qhov kev ntseeg tau ntawm kev ua haujlwm thiab ua tau raws li qhov ntsuas qhov tseeb ntawm N, nws yog ib qho tsim nyog yuav tsum nruj me ntsis xaiv cov ntaub ntawv thermal electrode. Cov kev cai dav dav rau cov ntaub ntawv thermal electrode hauv thaj tsam ntawm thermocouple engineering technology yog raws li hauv qab no:
(1) Paired thermocouples yuav tsum muaj lub peev xwm loj, thiab lub peev xwm thermoelectric muaj ib qho txiaj ntsig zoo ntawm kev sib raug zoo nrog qhov kub thiab txias;
(2) ruaj khov lub cev thiab tshuaj ua haujlwm yuav tsum tau ua raws li qhov ntsuas kub. Tsis yooj yim oxidized los yog corroded:
(3) Lub tshuab hluav taws xob txwv qhov kub thiab txias muaj ib qho kev qhia me me thiab kev ua haujlwm siab:
(4) Zoo rov tsim dua tshiab, zoo heev craftsmanship thiab interchangeability, thiab zoo durability rau yooj yim ua rau hauv txhob lo lo ntxhuav. (pt100)
Txhawm rau tiv thaiv luv luv ntawm ob txoj hlua hluav taws xob, lub tes tsho rwb thaiv tsev yuav tsum tau siv los cais ob lub xov hlau. Cov ntaub ntawv ntawm lub tes tsho rwb thaiv tsev feem ntau tuaj yeem txiav txim siab raws li qhov ntau ntawm cov av ntsuas
Tam sim no, hom thermocouple sensor qauv uas tau tsim cov khoom yog complex. Thaum xaiv thiab tsim cov thermocouples, nws feem ntau pom zoo kom xav txog cov yam ntxwv ntawm kev hnav-resistant thermocouple sensors thiab xaiv hom xws li cov thermocouples, Kai mounted thermocouples, los yog nyias zaj duab xis thermocouples. Nyob ntawm kev siv sib txawv, hom xws li cov thermocouples sab nraud, cov thermocouples ceev, ntau lub ntsiab lus thermocouples, lossis lub tshuab nqus tsev thermocouples kuj tuaj yeem xaiv nyias.
