Dab tsi yog qhov sib txawv ntawm cov zis tam sim no thiab cov hluav taws xob voltage

Thaum xaiv cov kev txiav txim siab tseem ceeb, ib qho ntawm cov kev txiav txim siab tseem ceeb ntawm cov zis (xws li {{{v, {v, {v, thiab lwm yam). Ob hom liab liab muaj qhov sib txawv thiab cov kev txwv, ua rau lawv haum rau cov ntawv thov sib txawv. Nkag siab cov kev sib txawv no tuaj yeem pab kom ntseeg tau cov kev ua tau zoo thiab kev ntseeg tau hauv koj qhov ntsuas.

Dab tsi yogNiaj hnubTso zis?

Cov teeb meem tam sim no yog ib hom hluav taws xob siv hluav taws xob uas siv los ntawm cov ntsuas hluav taws xob, thiab cov twj siv rau lwm cov khoom siv, xws li cov tswj hwm, cov ntaub ntawv log tsheb, lossis cov ntaub ntawv. Cov zis tam sim no yog {{0}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}, 0 txog 20MA, thiab 4 rau 20mA.

Nyob rau hauv cov zis tam sim no, lub teeb liab kis tau raws li kev ncaj qha tam sim no (DC)|{{{4-20 ma ma nplai rau cov ntawv thov kev lag luam. Tus nqi tam sim no sib haum rau cov ntsuas ntsuas, xws linyem, kub, lossisTxaus tus nqi.

Cov txiaj ntsig zoo ntawm cov khoom tso zis tam sim no:

• Ntev kis nrug: Txij li cov cim tam sim no tsis tshua muaj peev xwm tiv taus ntev ntev khiav,} ma cov cim tuaj yeem mus deb dua yam tsis muaj kev txhawj xeeb.
• Cov suab nrov tiv thaiv kab mob: Cov cim tam sim no muaj kev cuam tshuam tsawg dua los ntawm cov hluav taws xob hluav taws xob hauv hluav taws xob (EMI), ua rau lawv muaj zog rau cov chaw muaj kev nyab xeeb.
• Txhaum Nrhiav Kom Tau: 4MA inceleline (hloov 0 ma) tso cai rau kom yooj yim nrhiav kom tau yooj yim ntawm qhib kev ncig lossis sensor ua tsis tsaug zog.
• Cov cim sib xws: Qhov tsis zoo ntawm cov paib hluav taws xob, cov cim tam sim no tseem tsis tau hais txog cov kav hlau ntev lossis hluav taws xob tsis kam.
• Cov Qauv Txheej Txheem: the {{4-20 ma teeb liab yog siv dav hauv kev siv tshuab automation, ua rau muaj ntau tus tswj hwm, plcs, thiab tshuaj xyuas cov tshuab.

Cov kev txwv ntawm cov zis tam sim no:

Cov sensors siv cov loops tam sim no xav tau zog ntau dua Voltage-raws sensors.

Dab tsi yog voltage tso tawm?

Cov zis tawm ntawm cov teeb meem tsim hluav taws xob tsim ib qho hluav taws xob voltage teeb liab rau cov ntsuas ntsuas. Cov cuab yeej tau txais (piv txwv, PLC, cov ntaub ntawv logger) kev sib cav txog qhov ntsuas hluav taws xob los txiav txim qhov ntsuas. Cov zis tawm voltage voltage yog {{0}}} {}}}. 5v, thiab 0 txog 10V.

Cov txiaj ntsig zoo ntawm cov hluav taws xob voltage:

• Yooj yim cov qauv tsim: voltage cov zis sensors yuav tsum muaj tsawg zog thiab yooj yim dua los sib xyaw ua ke rau hauv cov voj voog pib.
• Cov hluav taws xob tsawg: piv rau {4-20 ma loops, voltage raws sensors haus lub zog tsawg dua.
• Kev ntsuas thiab daws teeb meem yooj yim dua thiab ntsuas cov qib voltageter yog ncaj ncees, ua kom haum thiab kuaj mob yooj yim dua.
• Haum rau cov ntawv thov luv luv: Yog tias lub teeb liab tsis tas yuav mus ncig ua si ntev, cov hluav taws xob voltage tuaj yeem muab cov kev nyeem tseeb yam tsis muaj kev txhawj xeeb.

Txwv ntawm cov hluav taws xob voltage:

• Daim phiajcim teeb meem deb: voltage dauv vim yog cov hlau tsis kam tuaj yeem cuam tshuam rau kev ntsuas qhov tseeb, tshwj xeeb hauv kev mus ntev.
• Kev ua tau ntau dua rau EMI: cov cim ntsuas hluav taws xob muaj ntau dua rau cov tshuab hluav taws xob hluav taws xob sab hauv cov tshuab machinery thiab hluav taws xob.
• Tsawg txhaum kev txhaum lub peev xwm: tsis zoo li lub tshuab hluav taws xob tsis zoo li no, cov tshuab hluav taws xob hluav taws xob tsis yooj yim ntes cov qhib kev ua tsis pom kev.

Thaum Twg Yuav Xaiv Cov Tso Tawm Tam Sim No

• Ntev-Deb Qhov Kev Tiv Thaiv Tsheb Loj, piv txwv li, cov ntawv thov xyuas chaw taws teeb
• Harsh kev muaj kev muaj thaj chaw ib puag ncig, qhov twg EMI yog kev txhawj xeeb
• Daim ntawv thov tseem ceeb, qhov twg tsis ua haujlwm pom yog qhov tsim nyog
• Kev Siv Automation thiab Tswj Lub Tshuab, Plcs, Scada, Muaj Kev Muaj Hluav Taws Xob
• Xav ncaj qha tsav cov khoom siv hluav taws xob tsawg

Thaum xaiv voltage tso zis (0-10 v, 1-5 v, thiab lwm yam)

• Luv-deb-deb kis tau tus kis, piv txwv li, tshuaj xyuas hauv zos
• Tsawg-lub zog siv hluav taws xob
• Lab lossis tswj cov chaw ib puag ncig, qhov twg EMI yog tsawg heev
• Cov tshuab yooj yim, qhov twg yooj yim sib koom ua ke
