Txawm hais tias tsis muaj kev tiv thaiv txheej ntawm cov kab hluav taws xob kub cuam tshuam rau kev siv feem ntau yog nyob ntawm hom cable thiab ib puag ncig uas nws siv.
Rau PT100 platinum thermal resistors, shielded xov hlau feem ntau tsis tas yuav tsum tau. Qhov kub thiab txias ntawm PT100 platinum thermal resistors feem ntau siv peb cov xov hlau, thiab cov khoom siv thiab qhov ntev ntawm peb cov xov hlau no yuav tsum ua kom zoo ib yam los xyuas qhov tseeb ntawm qhov ntsuas. Hauv qhov no, cov kab hluav taws xob tiv thaiv tsis tsim nyog.
Txawm li cas los xij, rau lwm hom kab hluav taws xob kub, lub luag haujlwm ntawm cov txheej thaiv thaiv yog tsuas yog txo cov electromagnetic cuam tshuam. Cov txheej thaiv tiv thaiv tuaj yeem tiv thaiv qhov chaw electromagnetic los ntawm kev cuam tshuam nrog cov teeb liab sab hauv ntawm lub cable thiab tiv thaiv kev ruaj ntseg ntawm cov teeb liab. Yog hais tias lub cable yog nyob rau hauv ib puag ncig nrog ib tug muaj zog electromagnetic teb, tsis muaj ib tug shielding txheej yuav ua rau cov teeb liab cuam tshuam thiab cuam tshuam qhov tseeb ntawm kev ntsuas.
Lub luag haujlwm ntawm cov txheej txheem tiv thaiv
Txo cov kev cuam tshuam electromagnetic: Cov txheej thaiv tiv thaiv tuaj yeem txo qhov cuam tshuam ntawm sab nraud electromagnetic teb ntawm cov teeb liab sab hauv ntawm cable thiab tiv thaiv kev ruaj ntseg ntawm cov teeb liab.
Tiv thaiv kom tsis txhob muaj kev puas tsuaj: Thaum lub sij hawm xob laim lossis hluav taws xob hluav taws xob, cov ntaub thaiv npog tuaj yeem tiv thaiv kev puas tsuaj rau cov khoom siv sab hauv ntawm lub cable.
Hom hom impedance: Cov txheej thaiv thaiv kuj tseem tuaj yeem txo cov hom impedance ntawm daim phiaj hluav taws xob thiab tiv thaiv cov cuab yeej xws li kev sib txuas lus los ntawm kev puas tsuaj.
Qhov sib txawv ntawm qhov yuav tsum tau ua rau ntau hom kub cables
PT100 platinum thermal resistor: Feem ntau tsis tas yuav tsum muaj cov ntaub thaiv npog, thiab cov khoom siv thiab qhov ntev ntawm peb cov xov hlau yuav tsum ua kom zoo ib yam.
Thermocouple kub sensor: Kev them nyiaj xaim yuav tsum tau, thiab cov hlau thaiv kev tiv thaiv feem ntau yuav tsum tau txo qis ntsuas qhov yuam kev.
