Lub siab transmitter yog dab tsi?

Lub siab transmitter yog tsim los ntawm plaub qhov tseem ceeb: lub ntsiab lus, lub teeb liab ua haujlwm, lub zog hluav taws xob, thiab cov khoom siv hluav taws xob.Lub ntsiab lus pom tau yog tsim los hloov lub cev hloov pauv (siab) rau hauv lub teeb liab hluav taws xob, uas yog pub rau hauv kev ua haujlwm. Cov txheej txheem ua haujlwm ua kom muaj zog thiab hloov cov teeb liab mus rau hauv cov qauv qauv, feem ntau yog 4-20 mA lossis cov teeb liab digital. Cov khoom siv hluav taws xob muab cov hluav taws xob tsim nyog rau kev ua haujlwm ntawm lub tshuab xa hluav taws xob, thaum cov khoom siv hluav taws xob xa tawm cov teeb liab txheem rau kev tswj hwm.
Muaj ntau hom kev siab transmitters, raws li lawv cov ntsiab lus sensing. Feem ntau hom yog piezoresistive, capacitive, thiab resonant siab sensors.Piezoresistive sensors siv cov khoom siv lead ua uas hloov nws cov nqi tiv thaiv thaum raug siab. Capacitive sensors ntsuas qhov kev hloov pauv ntawm lub peev xwm ntawm ob lub electrodes raws li kev hloov siab. Resonant sensors ntsuas lub ntuj zaus ntawm qhov ntsuas qhov ntsuas uas txawv nrog lub siab.
Cov khoom siv hluav taws xob siab yog siv rau ntau yam kev lag luam, xws li roj thiab roj, petrochemical, hluav taws xob tsim hluav taws xob, tshuaj, thiab zaub mov thiab dej haus.Lawv muaj ntau yam kev siv, suav nrog kev ntsuas siab, tswj, thiab saib xyuas cov twj, compressors, pipelines, boilers, thiab reactors. Lawv kuj tau siv nyob rau hauv kev ruaj ntseg systems, qhov chaw uas lawv ua raws li kev ruaj ntseg kaw los yog tswb.
Qhov zoo ntawm kev siv cov tshuab xa hluav taws xob muaj xws li qhov tseeb thiab kev ntseeg siab, qhov kub thiab txias ntau yam, thiab tiv thaiv kev cuam tshuam ntawm electromagnetic cuam tshuam.Lawv kuj xav tau kev saib xyuas tsawg thiab yooj yim rau nruab thiab khiav lag luam. Ntxiv mus, lub siab transmitters tuaj yeem ua ke nrog lwm cov sensors thiab tswj cov khoom siv los tsim kom muaj kev tswj xyuas tiav.
Hauv kev xaus,lub siab transmitter yog ib qho cuab yeej tseem ceeb siv nyob rau hauv ntau yam lag luam los ntsuas thiab tswj lub siab ntawm cov kua thiab gases.. Nws muaj plaub qhov tseem ceeb: lub ntsiab lus pom, lub teeb liab ua haujlwm, lub zog hluav taws xob, thiab qhov hluav taws xob tso tawm. Cov tshuab xa hluav taws xob muaj ntau hom kev ntsuas qhov ntsuas, thiab lawv muaj ntau qhov zoo ntawm qhov raug, kev ntseeg tau, thiab kev siv yooj yim. Lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb, raug, thiab ua haujlwm zoo hauv cov txheej txheem kev lag luam.
