Cov tshuab hluav taws xob txhaj tshuaj molding tshuab (EIMMs) siv siab- ceev digital servo motors, siab- zaus tsav, tshuab hluav taws xob rov ua dua tshiab, thiab qis-voltage siab- tam sim no fais fab kev faib tawm. Cov tshuab no ua rau muaj kev cuam tshuam ntawm electromagnetic cuam tshuam (EMI) thiab xov tooj cua -frequency interference (RFI) uas cuam tshuam tag nrho cov qauv thermocouple signals. Nyob rau hauv EIMM ib puag ncig, tus qauv tsis muaj kev tiv thaiv lossis tsis zoo tiv thaiv cov thermocouples tsim tsis ruaj khov, flickering, los yog kev nyeem ntawv kub tsis zoo.
Thermocouple signals yog ntsuas nyob rau hauv microvolts- me me uas txawm tias tsis muaj zog hluav taws xob nrov distorts lawv dhau kev paub. Ntawm cov tshuab hluav taws xob, lub suab nrov tuaj yeem ua rau kev nyeem ntawv kub kom viav vias ± 10℃lossis ntau dua, txawm tias qhov ntsuas kub tiag tiag. Tus maub los teb los ntawm kev siv lub tshuab hluav taws xob sai sai, tsim kom muaj qhov sib txawv ntawm cov viscosity, ntws inconsistency, thiab qhov tsis xws luag.
Lub suab nrov-immune thermocouples rau EIMMs yog tsim los nrog plaub yam tseem ceeb: tag nrho cov hlau nplaum tiv thaiv, kev sib cais sib tw-pair conductors, ungrounded junction design, thiab kaw, shielded connectors.
Tag nrho cov hlau nplaum tiv thaiv kev tiv thaiv tsim ib lub tawb Faraday txuas ntxiv nyob ib ncig ntawm lub teeb liab - nqa cov khoom siv, thaiv cov hluav taws xob sab nraud. Lub braid yog grounded ntawm tus maub los kawg kom ntws cuam tshuam kev nyab xeeb.
Twisted -pair conductors tshem tawm lub suab nrov los ntawm kev sib npaug ntawm qhov sib txawv. Txhua qhov twist thim rov qab lub polarity ntawm induced voltage, ua rau net-zero nrov tsub zuj zuj.
Ungrounded junctions- qhov twg cov xaim hlau xaim hluav taws xob raug cais tawm ntawm lub plhaub- tiv thaiv hauv av- lub suab nrov, qhov tseem ceeb ntawm kev cuam tshuam hauv cov tshuab hluav taws xob. Grounded junctions tuaj yeem tsim lwm txoj hauv kev tam sim no uas ua kom nrov nrov.
Muab kaw, hlau-plhaub connectors tuav thaiv kev txuas mus rau tus maub los. Tsawg- cov khoom sib txuas yas zoo ua txhaum txoj hauv kev tiv thaiv thiab tso cai rau cov suab nrov nkag.
Ntau cov molders hloov los ntawm hydraulic mus rau lub tshuab hluav taws xob xav tsis thoob los ntawm cov teeb meem zoo, tsis paub txog qhov teeb meem yog hluav taws xob cuam tshuam. Txhim kho tag nrho cov ntaub thaiv npog, tsis muaj av, suab nrov- tiv thaiv MI thermocouples tam sim ntawd rov qab ruaj khov.
Hauv kev tsim khoom niaj hnub no, EIMMs tau dhau los ua tus qauv vim qhov tseeb, lub zog ua haujlwm tau zoo, thiab nrawm. Rau cov molders siv tshuab hluav taws xob, suab nrov -cov thermocouples tiv thaiv kab mob tsis yog xaiv tau-lawv yuav tsum tau ua haujlwm kom ntseeg tau.
