Grounded thiab ungrounded junction structures sawv cev rau ob tug tseem ceeb kev faib cov qauv ntawm kub khiav thermocouples, nrog pom tseeb qhov khoob ntawm cov tshuaj tiv thaiv ceev, tiv thaiv - cuam tshuam kev ua tau zoo thiab muaj feem xyuam rau txoj hauj lwm, feem ntau tsis meej pem cov neeg yuav khoom thiab ntawm - chaw tu cov kws kho mob thaum hloov khoom seem. Qhov sib txawv tseem ceeb tshwm sim los ntawm kev sib txuas ntawm qhov sib txuas ntawm cov thermocouple welding hlws ris thiab sab hauv stainless hlau sheath: grounded hom qhov hnov qhov chaw yog nruj nreem welded thiab hluav taws xob txuas nrog sheath phab ntsa, thaum ungrounded hlws ris yog kiag li cais tawm ntawm lub plhaub los ntawm ntom magnesia rwb thaiv tsev hmoov yam tsis muaj hluav taws xob conduction ntawm core alloy hlau thiab hlau casing.
Grounded thermocouple hloov cov cua sov sai sai ntawm kev sib cuag hlau ncaj qha ntawm kev sib tshuam thiab cov sheath, xa cov lus teb ceev ceev thiab haum rau embedded installation hauv kub khiav manifold. Tom qab muab tso rau hauv manifold reserved mounting qhov, txheej sheath zoo haum manifold hlau lub cev thiab sai sai ua cua sov rau puab sensing taw tes rau taug qab tiag - lub sij hawm channel phab ntsa kub; feem ntau manifold embedded thermocouples ntawm Husky thiab Pwm-Masters multi-zone kub khiav tshuab txais kev tsim qauv hauv av. Txawm li cas los xij, cov qauv tsim hauv av dais tsis zoo los tiv thaiv -electromagnetic cuam tshuam muaj peev xwm; sheath txuas nrog kub khiav hlau thav duab yooj yim khaws cov stray tam sim no los ntawm cov cua kub uas nyob ib sab thiab solenoid li qub, ua rau cov ntaub ntawv kub kub dhia ntawm cov ntxaij vab tshaus, yog li hauv av thermocouples raug txwv tsis pub rau nruab ze siab - lub zog hluav taws xob hluav taws xob ntawm lub rooj vag kub khiav.
Ungrounded thermocouple fundamentally txiav tawm stray tam sim no txoj kev kis tau tus mob los ntawm tag nrho cais cov tub ntxhais hlws ris los ntawm txheej sheath thiab muaj zoo heev tiv thaiv - muaj peev xwm cuam tshuam, ua tus qauv bayonet nozzle thermocouple nyob ze cov cua kub coils thiab hydraulic valve Cheebtsam ntawm lub rooj vag valve systems. Txawm hais tias cov txheej txheej rwb thaiv tsev me ntsis ua rau cov cua sov ua kom qis thiab ua rau me me thermal hysteresis, refined ntxhia compressing tshuab tswj tag nrho cov kev ua yuam kev nyob rau hauv ± 0.3 degree, siab txaus siab - precision tswj yuav tsum tau ntawm automotive sab nrauv thiab pob tshab kho mob tivthaiv molding. Kev hloov pauv hauv tsev thermocouple rau YUDO thawj qhov kev hloov pauv nruj me ntsis cais cov ntsiab lus hauv av thiab tsis sib haum xeeb txhawm rau tiv thaiv kev teeb tsa tsis sib haum -ua rau muaj kev kub ntxhov tswj.
Kev hloov pauv tsis raug ntawm ob hom tsim ntau yam tsis xws luag: hloov cov khoom qub uas tsis muaj qhov tsis zoo ntawm cov thermocouple nrog cov khoom siv hauv av ua rau muaj qhov kub thiab txias tsis tu ncua, sib sib zog nqus overheating thiab lub rooj vag khoom scorch; Kev siv cov khoom siv tsis sib haum xeeb ntawm kev ntsuas manifold ua rau qhov ntsuas kub qeeb thiab qeeb PID cov lus teb, ua rau cov dej ntws tsis sib xws thiab cov phab ntsa tuab tsis sib haum thoob plaws ntau- kab noj hniav molded qhov chaw. Ua ntej xaj cov khoom siv thermocouples, cov neeg siv yuav tsum tau kuaj xyuas cov qauv qub qub lossis xa mus rau thawj cov chaw tsim khoom kub kub ua haujlwm phau ntawv qhia kom paub meej cov kev sib tshuam. Nrog rau kev txawj ntse kub khiav kev hloov kho dua tshiab, ib nrab- cais sib xyaw- qauv kev hloov kho thermocouple tshwm sim maj mam, ntsuas cov lus teb ua haujlwm thiab tiv thaiv-jamming cov cuab yeej rau cov khoom sib xyaw ua ke ntawm cov khoom siv hluav taws xob tshiab thiab dhau los ua qhov tseem ceeb R & D kev taw qhia rau thermocouple factories.
