Lub luag haujlwm ntawm Sensors Hauv Hluav Taws Xob Automation: Daim Ntawv Thov thiab Schneider Electric Khoom

Nyob rau hauv lub tshav pob ntawm niaj hnub industrial automation, sensors ua raws li "lub qhov muag" thiab "pob ntseg" ntawm kev tswj systems. Lawv yog cov khoom tseem ceeb uas hloov lub cev tsis muaj zog-xws li kub, siab, hloov chaw, thiab ceev-rau hauv hluav taws xob teeb liab. Cov teeb liab no tau ua tiav los ntawm cov tswj hwm xws li PLCs txhawm rau txhawm rau saib xyuas lub sijhawm tiag tiag thiab kev tawm tswv yim, tsim lub hauv paus ntawm qhov tseeb thiab txhim khu kev qha automation systems.

Nkag siab txog Txoj Cai Ua Haujlwm ntawm Sensors

Sensors ua haujlwm raws li lub cev lossis tshuaj lom neeg. Thaum lub ntsuas ntsuas hloov pauv, cov khoom hluav taws xob ntawm lub ntsuas ntsuas qhov ntsuas (piv txwv li, thermocouples, RTDs, capacitors, Hall ntsiab) hloov raws li. Cov kev hloov no tau hloov mus rau hauv cov cim nyeem tau xws li voltage, tam sim no, lossis zaus.

Piv txwv li:

• Kub sensors siv cov thermocouples lossis RTDs los tso tawm qhov sib txawv ntawm qhov voltage / tsis kam.
