Installation yuam kev Analysis: Yuav ua li cas Mounting Paub meej cuam tshuam tus Pin-Hom J Thermocouple raug
Feem ntau cov teeb meem ntsuas qhov tsis raug ntawm tus pin-hom J thermocouple hauv daim ntawv thov teb tsis yog tshwm sim los ntawm qhov ntsuas qhov zoo lossis cov khoom siv drift, tab sis los ntawm tsis yog - cov ntsiab lus ntawm kev teeb tsa tus qauv. Kev ua yuam kev me me hauv qhov tob tob, kho hom thiab kev tiv thaiv thermal yuav ua rau tsis muaj - qhov ntsuas kub tsis txaus, uas tsis tuaj yeem raug tshem tawm tom qab calibration thiab kev hloov pauv. Qhia meej txog kev teeb tsa kev ua yuam kev thiab cov txheej txheem mounting specifications yog lub hauv paus kom ua kom qhov tseeb qhov zoo ntawm tus pin-hom J thermocouple.
Tsis txaus siv qhov tob tob yog qhov feem ntau yuam kev installation. Tus pin- hom ntsuas qhov ntsuas kub yog nyob ntawm qhov ntsuas qhov ntsuas qhov kawg kom nkag mus rau qhov ntsuas kub tsis sib xws ntawm qhov nruab nrab ntsuas. Qhov ntxig ntxig ua rau qhov kev sojntsuam xaus rau hauv qhov kub hloov pauv txheej cuam tshuam los ntawm ambient tshav kub dissipation, uas ua rau tsis muaj qhov ntsuas qhov sib txawv. Hauv dynamic ntws nruab nrab thiab rotating cov cuab yeej, qhov tob tob yuav ua rau qhov kev sojntsuam tsis tuaj yeem ntes tau tiag tiag -lub sijhawm hloov pauv kub, ua rau muaj kev lag luam loj.
Loose fixing thiab vibration displacement induce intermittent ntsuas yuam kev. Pin-hom J thermocouple siv rau hauv cov cuab yeej siv tshuab ua haujlwm muaj kev cuam tshuam kev co tsis tu ncua. Xauv lub installation tsis tu ncua ua rau lub sijhawm hloov pauv ntawm qhov kev sojntsuam, ua rau qhov kev nkag siab kawg ntawm qhov siab - qhov kub thiab txias cheeb tsam thiab qis - qhov chaw hloov pauv kub. Qhov kev hloov pauv tsis tu ncua no ua rau random jitter ntawm cov ntaub ntawv kub, cuam tshuam rau kev ruaj ntseg ntawm kev tswj kub tsis siv neeg.
Kev tiv thaiv thermal ntau dhau ua rau qhov kub thiab txias sib txawv. Feem ntau muaj qhov sib txawv ntawm huab cua ntawm qhov kev sojntsuam sab nrauv phab ntsa thiab cov khoom siv mounting qhov sab hauv phab ntsa. Huab cua muaj cov thermal conductivity tsawg, uas cuam tshuam kev hloov pauv sai ntawm cov cuab yeej ntsuas thiab cov kev sojntsuam. Qhov ntsuas kub ntawm qhov ntsuas kub ib txwm qis dua qhov ntsuas kub ntawm cov cuab yeej siv, tsim qhov sib txawv zoo li qub. Qhov kev ua yuam kev no pom tseeb dua nyob rau hauv nruab nrab- qhov ntsuas kub tsis zoo li qub ntawm J-hom thermocouples.
Cov ntaub ntawv yuam kev ntawm ntau hom kev teeb tsa ntawm tus pin-hom J thermocouple tau qhia hauv cov lus hauv qab no:

Raws li kev paub debugging hauv teb, cov qauv kev teeb tsa ua haujlwm tuaj yeem tshem tawm ntau dua 90% ntawm tus pin- hom J thermocouple ntsuas qhov yuam kev. Qhov tseeb qhov tseeb ntawm qhov siab - zoo sensors tsuas yog siv tau los ntawm kev ua raws li kev teeb tsa, thiab kev teeb tsa tus qauv yog qhov yooj yim lav ntawm qhov ntsuas kub ntsuas qhov system stability.
Cov kws tshaj lij ntawm - qhov kev taw qhia kev teeb tsa ntawm qhov chaw tuaj yeem tsim cov txheej txheem kho cov txheej txheem thiab cov qauv ntxig raws li cov qauv khoom siv thiab lub xeev kev ua haujlwm, tshem tawm tag nrho kev teeb tsa- vim qhov ntsuas qhov yuam kev.
