Daim ntawv thov
Field Instrument Surge Protective Device yog tsim los tiv thaiv ntau yam khoom siv, suav nrog:
1.2-xaim, 3-xaim, thiab 4-xaim transmitters:Cov transmitters no feem ntau yog siv los ntsuas ntau yam tsis xws li siab, kub, qib, thiab lwm yam, nyob rau hauv qhov chaw muaj kev phom sij.
2.Thermocouples (TC) thiab Resistance Temperature Detectors (RTD):Cov ntsuas kub no feem ntau ua haujlwm hauv cov txheej txheem kev lag luam los ntsuas qhov ntsuas kub kom raug thiab ntseeg tau.
3.Kev sib txuas lus sib txuas xws li RS485, RS232, thiab RS422:Cov interfaces no yog siv rau cov ntaub ntawv sib txuas lus ntawm cov khoom siv sib txawv, kom ntseeg tau tias muaj kev sib raug zoo thiab kev sib koom ua ke tsis sib haum hauv cov tshuab.
4.Flow meters:Flow meters yog siv los ntsuas tus nqi ntws ntawm cov kua lossis roj hauv cov kav dej lossis cov tshuab, muab cov ntaub ntawv tseem ceeb rau kev tswj xyuas cov txheej txheem.
5.Electromagnetic li qub:Cov li qub no tswj cov dej ntws hauv cov txheej txheem kev lag luam thiab tseem ceeb heev rau kev tswj kev txav ntawm cov kua lossis roj hauv cov kav dej.
