1.Type DesignationThermocouple type designation yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm qhov ntsuas kub ntawm qhov chaw ntsuas qhov kub thiab txias (saib "Kev Pom Zoo Ua Haujlwm Kub Ua Haujlwm rau Thermocouples"). Cov nyiaj them poob haujlwm ntawm tib hom kev xaiv yuav tsum tau siv los txuas rau cov khoom siv / tswj ntawm tib hom kev xaiv.
2.Measuring Junction TypeAssembled thermocouples feem ntau yog hom insulated, thiab tuaj yeem yog hom kev sib tshuam hauv av (piv txwv li, qis-inertia thermocouples).Thermocouple ntsiab tseem tuaj yeem siv ncaj qha yam tsis muaj lub raj tiv thaiv.Mineral-insulated (MI) thermocouples muaj xws li insulated thiab grounded hom; Hom insulated feem ntau yog siv.Grounded hlws ris thermocouples muaj lub sij hawm thermal teb sai dua tab sis muaj kev cuam tshuam rau electromagnetic cuam tshuam, yuav tsum tau txhim khu kev qha earthing ntawm cov txheej sheath.
3. Cov khoom siv tiv thaiv tube
Kev siv dav dav: Stainless hlau 1Cr18Ni9Ti.
Corrosive atmospheres: 1Cr18Ni12MoTi lossis SUS316L.
Muaj zog oxidizing media xws li sulfuric acid, nitric acid, hydrochloric acid: Tantalum raj los yog Hastelloy alloy.
Tshaj 900 degree: Kub-resistant steel Cr25Ti los yog SUS310S.
Tshaj 1000 degree: Siab- kub alloy lossis siab -alumina corundum ceramic raj.
Saum 1300 degree: Corundum ceramic raj.
Nqus, inert los yog txo cua sov: Aluminium, tantalum los yog tungsten raj.High-alumina thiab corundum tiv thaiv tubes tsis haum rau siv nyob rau hauv cov huab cua uas muaj ya raws los yog txo gases.
4.Txoj kab uas hla thiab Length ntawm kev tiv thaiv tube Qhov loj ntawm txoj kab uas hla ntawm lub raj tiv thaiv, lub thermal teb lub sij hawm ntev thiab qhov zoo ntawm cov khoom siv kho tshuab.Rau qhov ntsuas kub hauv qab 600℃yam tsis muaj cov txheej txheem tshwj xeeb, cov ntxhia pob zeb -insulated thermocouples nrog cov kab me me feem ntau xaiv.Thermocouples ntsuas qhov kub ntawm qhov kub ntawm cov txheej txheem welding yuav tsum tau txiav txim siab ntev. Tag nrho qhov ntev ntawm cov thermocouple feem ntau yog qhov ntxig ntev + 150 lossis 100, lossis + 250.Yuav kom ntsuas qhov ntsuas kub kom raug, qhov ntev ntawm cov thermocouples sib dhos rau hauv qhov ntsuas nruab nrab feem ntau yuav tsum muaj ntau dua 100 mm.
5.Mounting thiab kho ntaus ntawv
Tsis yog- daim ntawv thov raug kaw: Tsis muaj kev kho cov cuab yeej, txav tau flange, xov ferrule txav tau, lossis txav tau ferrule flange.
Daim ntaub ntawv kaw lus: Threaded lossis flange mounting.
Common specifications:
Sib dhos thermocouples: Feem ntau siv xov M27 × 2; flanges φ95 (rau φ16 tiv thaiv raj) lossis φ105 (rau φ20 tiv thaiv raj).
MI thermocouples φ2/3/4: Xov M12 × 1.5, ferrule flange φ55.
MI thermocouples φ5/6/8: Xov M16 × 1.5, ferrule flange φ65.
Txuas lub raj ntawm MI thermocouples: Feem ntau siv xov M20 × 1.5.
6.Mounting and Wiring DeviceThe mounting and wiring device yuav tsum xaiv kom yooj yim thiab ntseeg tau.
Mineral-insulated thermocouples yam tsis muaj hlws ris lub thawv: Ceramic terminal board, connectors, tiv thaiv cap nrog them cable, tiv thaiv cap nrog hlau hose thiab them cable.
Sib dhos cov thermocouples yam tsis muaj hlws ris lub thawv: Terminal board, yooj yim xaim posts.Thermocouples nrog hlws ris lub thawv yog tsuas yog siv nyob rau hauv plua plav, waterproof thiab tawg- pov thawj ib puag ncig,
suav nrog: lub thawv dej tsis muaj dej tsis sib haum, tiv thaiv- lub thawv ntim tshuaj tsuag, lub thawv sib txuas flameproof, hlws ris lub thawv nrog cov zaub hauv zos, thiab ntau- taw tes hlws ris lub thawv.
