Qhov txawv ntawm J-Hom thiab K-Hom Thermocouples yog dab tsi?

J-hom thiab K- hom thermocouples yog ob lub ntsuas kub uas siv ntau tshaj plaws hauv cov tshuab kub khiav, txhua tus muaj cov yam ntxwv sib txawv haum rau cov xwm txheej sib txawv. Kev nkag siab txog lawv qhov sib txawv pab cov neeg siv xaiv qhov zoo sensor rau cov kev cai molding tshwj xeeb. J- hom thermocouples, muaj li ntawm cov hlau thiab qhov tsis sib xws, muab qhov tseeb thiab ruaj khov ntawm qhov kub nruab nrab, feem ntau yog li ntawm -40 ° C txog 750 ° C. Lawv muab cov khoom siv hluav taws xob siab tshaj plaws thiab cov nqi ua haujlwm, ua rau lawv nrov rau cov khoom siv dav dav xws li PP, PE, ABS, thiab PS. Txawm li cas los xij, J- hom sensors tsis tshua muaj resistant rau siab -kub oxidation thiab tsis zoo rau lub sij hawm ntev - siv tshaj 600 ° C. Cov ceg hlau yog qhov yooj yim rau corrosion thiab oxidation nyob rau hauv siab - qhov kub thiab txias ib puag ncig, uas ua rau lub neej ua haujlwm luv. K-hom thermocouples, ua los ntawm chromel thiab alumel, muaj qhov dav dav ntawm qhov kub ntawm -200 ° C txog 1250 ° C thiab oxidation zoo heev. Lawv muaj kev ruaj khov dua ntawm qhov kub thiab txias thiab haum rau cov yas yas xws li PC, PA, PBT, PPS, thiab PEEK uas yuav tsum tau ua kom sov dua. K- hom sensors yog qhov ruaj khov dua nyob rau hauv kev txuas ntxiv thermal cycling thiab tsawg cuam tshuam los ntawm ib puag ncig corrosion. Txawm li cas los xij, lawv yog me ntsis rhiab dua J- hom ntawm qhov kub thiab txias thiab feem ntau raug nqi me ntsis ntxiv. Ib qho kev txiav txim siab tseem ceeb tshaj plaws yog kev sib raug zoo nrog lub ntsuas kub. Kev siv K-hom thermocouple nrog J- hom kev teeb tsa lossis rov ua dua yuav ua rau muaj qhov yuam kev loj. Feem ntau, J- hom yog nyiam rau cov qauv, qis- rau- nruab nrab kub daim ntawv thov, thaum K- hom yog pom zoo rau high-temperature engineering cov ntaub ntawv thiab mus ntev ntau lawm. Kev xaiv hom raug ua kom muaj kev tswj xyuas qhov kub thiab txias, txuas ntxiv lub neej ntawm lub sensor, thiab txhim kho tag nrho cov kub khiav kev ntseeg tau.
