Dab tsi txaus ntshai tshwm sim los ntawm Mismatched Thermocouple Compensating Extension Wires?

Thermocouple compensating extension xov hlau yog tsim nyob rau hauv tib lub alloy ratios raws li cov thawj sensing xov hlau los muab kev sib kis ntawm thermoelectric signals tshaj ncua ncua deb ntawm kub khiav mus rau tej thaj chaw deb tswj kub. Txhawm rau txuag cov nuj nqis nyob rau lub sijhawm luv luv, ntau pab pawg saib xyuas yuav siv cov khoom siv tooj liab lossis cov kab txuas txuas tsis sib haum uas yuav qhia txog qhov kub thiab txias tsis tu ncua offset, teeb liab attenuation thiab zais luv luv - Circuit Court txaus ntshai uas yuav ua rau kub khiav molding zoo nyob rau lub sijhawm. Cov txheej txheem tsis ua hauj lwm thiab cov txheej txheem txuas ntxiv xaim sib piv cov qauv raug tshuaj xyuas, uas tuaj yeem zam qhov kev phom sij zais vim los ntawm kev xaiv tsis tsim nyog ntawm cov cables.

Lub alloy mismatch ua rau tsis xav tau lwm yam kev sib txuas txias txias uas muab qhov ntsuas kub ruaj khov. Qhov sib txawv ntawm cov hlau sib txuas yog tsim thaum K-hom thermocouples raug xaim nrog J- hom kev them nyiaj txuas ntxiv cables, tsim cov cim ntxiv hluav taws xob millivolt tsis cuam tshuam nrog kub khiav kub ntawm qhov chaw xaim splice. Qhov kev sib tshuam txias kho algorithm nyob rau hauv tus maub los tsuas yog them nyiaj rau offset ntawm lub txee lub davhlau ya nyob twg thaiv thiab tsis yog rau ib qho ntxiv voltage tsim ntawm mismatched splices. Qhov no ua rau qhov ntsuas tsis raug ntawm 2℃txog 6 degree. Qhov kev tsis ncaj ncees zoo li no ua rau cov neeg ua haujlwm txuas ntxiv nce lossis txo qis hauv cheeb tsam teeb tsa qhov kub thiab txias, uas ua rau cov yas yas overheating thiab cov teeb meem tsis tiav hauv txhua pawg ntawm cov khoom. Siv cov tooj liab dawb huv raws li cov kab txuas txuas ntxiv ua rau muaj qhov yuam kev exponentially compounded . Copper ua rau muaj kev hloov pauv ntawm cov thermoelectric tseem ceeb thaum spliced ​​rau nickel{10}} alloy thermocouple xov hlau .

Tsawg zoo nyias gage txuas xov hlau ua rau cov teeb liab loj loj poob ntawm cov kab txuas ntev ntev. Cov peev nyiaj 24AWG them nyiaj cables muaj ib qho me me alloy conductor hla ntu nce tag nrho lub voj tsis kam rau cov xaim ntev tshaj 5 meters. Thermoelectric signals ncav cuag tus maub los yog tsis muaj zog, thiab yog li kub khiav kub yog tsis tu ncua underread. Lub kaw lus tau ua kom lub zog cua sov tas li kom them nyiaj rau qhov tsis tshua pom muaj txiaj ntsig, tsim cov chaw kub hauv zos ntawm nozzles thiab manifolds uas decompose yas resin thiab tsim cov pa roj carbon dub rau ntawm qhov chaw molded. Heavy luag hauj lwm 16-20AWG matched compensating xov hlau tshem tawm lub voj tsis kam rau ntev nyob deb txee tsim kom muaj tag nrho cov teeb liab lub zog uas tsis muaj kev ceeb attenuation.

Cov kab txuas txuas ntxiv tsis muaj cov txheej txheem tiv thaiv, ua rau muaj suab nrov nrov ntawm electromagnetic cuam tshuam. Unshielded mismatched txuas ntxiv ua rau yog cov kav hlau txais xov loj loj uas tuaj yeem khaws cov hlau nplaum sib nqus los ntawm kev txhaj tshuaj molding servo motors, high tam sim no cua sov coils thiab zaus inverters. Lub tshuab ua haujlwm ua rau tsis xwm yeem dhia hauv qhov kub ntawm 3-5℃. Qhov no destabilizes PID fais fab hloov thiab ua rau cov fluidity sib txawv ntawm cov yaj ntawm molding cycles. Rhiav cov suab nrov sib nqus tsis tuaj yeem cuam tshuam los ntawm ib qho kev txuas ntxiv, tsis yog qib - sib txuam, tsis muaj hlau braided shielding. Cov kab hluav taws xob thiab tsheb tsim khoom siv nrog cov khoom siv ceev ceev yuav tsum tau muab ob npaug rau - txheej ntawv ci - thiab-braid shielding.

Kev sib txuas tsis raug thiab kev sib khi ntawm cov xov hlau tsis sib haum yuav ua rau kom tawg ntawm cov rwb thaiv tsev sab hauv. Cov kws tshaj lij hauv teb feem ntau koom nrog cov kab txuas txuas ntxiv uas tsis tsim nyog nrog cov hlau tsis muaj hlau tsis zoo, tawm hauv cov ntsiab lus sib txawv ntawm cov hlau sib txuas mus rau cov huab cua ntub dej. Condensation ntawm splice qhov chaw tsim ion txheej uas yog conductive, ua rau lub sij hawm luv luv Circuit Court tswb thiab unpredictable cheeb tsam cua sov shutdowns. Corrosive yas volatile vapors permeate unprotected splices thiab corrode alloy conductors, ua rau muaj zog teeb liab drift thaum lub lis piam ntawm tas mus li ntau lawm. Qhov no yog ua tiav los ntawm kev pom zoo cov tswv yim ntawm kev sib txuas siv tsuas yog cov thermocouple alloy taub qab txuas ntawm tib qib nrog kub kub kub shrink sealing npog kom tsis suav nrog cov kev sib txuas txias txias thiab noo noo nkag.

Kev yuav khoom & kev teeb tsa cov cai yog tus qauv kom tsis txhob muaj kev phom sij ntawm kev txuas ntxiv hlau tsis sib haum. Txhua qhov kev txiav txim rau cov thermocouple extension cable yuav tsum qhia meej qhov sib txuam qib (K / J / N / E), hlau gage thiab shielding configuration kom phim cov kub khiav sensors. Txhua qib ntawm cov nyiaj them rov qab tau muab khaws cia rau hauv cov kab ntawv cais cais kom tsis txhob sib xyaw sib xyaw thaum xaim. Rau cov pwm retrofits uas koom nrog kev hloov cov kab txuas ntxiv, cov kws tshaj lij tshem tawm cov kab tsis sib haum thiab rov-khiav qib- cov kab sib txuas hauv lawv tag nrho es tsis txuas cov xov hlau txuas mus rau cov hlua qub uas tsis sib xws. Spare extension cable inventory is classified by the thermocouple grade with clear color-coded packing markings to avoid uninttentional xaiv ntawm incompatible cables thaum muaj xwm ceev tu.
