Yuav ua li cas kuaj pom qhov ua rau tsis ruaj khov thermocouple signals?

Thermocouples feem ntau yog siv qhov ntsuas qhov ntsuas kub, tab sis qee zaus lawv cov lus ceeb toom tuaj yeem ua rau tsis muaj zog.
Kev xaim tsis zoo ntawm cov thermocouples yog ib qho uas tsis yog qhov txawv txav. Yog tias cov hlua txuas tsis tau txuas los yog tsis zoo, nws yuav ua rau muaj kev cuam tshuam ntawm kev sib kis, cuam tshuam rau qhov raug thiab sib npaug ntawm qhov ntev. Piv txwv li, nyob rau hauv ib puag ncig kub ntau dhau, kev sib txuas hauv xov tooj kuj tseem tuaj yeem ua kom tsis muaj kev ruaj ntseg vim yog thermal o thiab contraction.
Qhov qis dua ntawm kev rwb thaiv tsev tag nrho ntawm cov thermocouples kuj tuaj yeem ua rau muaj teeb meem. Thaum cov txheej txheej rwb thaiv tsev puas lawm, nws tuaj yeem qhia txog kev cuam tshuam kev ceeb toom, ua rau muaj kev hloov pauv hauv qhov loj me. Piv txwv li, tom qab siv txuas ntxiv, txheej rwb thaiv tsev kuj tseem tuaj yeem muaj hnub nyoog thiab tawg.
Qhov teeb meem teeb tsa ua haujlwm ntawm thermocouples tsis tuaj yeem tsis quav ntsej. Yog tias tsim nyob rau hauv cov cheeb tsam uas muaj kev hloov kho qhov kub thiab txias lossis muaj zog electromagnetic cuam tshuam, nws kuj yuav ua rau muaj kev cuam tshuam tsis ruaj khov. Piv txwv li, thaum los ze rau cov khoom siv hluav taws xob ntau dhau, nws tuaj yeem nyuaj rau electromagnetic cuam tshuam.
Tsis tas li ntawd, kev laus los yog kev puas tsuaj ntawm cov tshuaj thermocouple kuj yog ib qho tseem ceeb. Lub sij hawm ntev tshaj tawm rau qhov hnyav khiav ib puag ncig kuj tseem tuaj yeem ua rau muaj kev cuam tshuam corrosion, deformation, thiab cov teeb meem sib txawv nrog cov thermocouples, yog li cuam tshuam rau kev sib npaug.
Qhov ntsuas hluav taws xob tsis zoo ntawm lub thermocouple kuj yuav yog tus neeg ua txhaum. Piv txwv li, tsis muaj zog amplifier zuag qhia tag nrho kev ua tau zoo thiab tsis ua hauj lwm ntawm filtering capacitors tuaj yeem ua rau muaj kev hloov pauv hauv qhov kos npe ntawm thermocouples.
