Dab tsi yog lub cim colutterator?
Tus Cim Raug Rho Tawmyog ib hom ntawm cov khoom siv tshuab hluav taws xob uas cuam tshuam cov phiaj xwm hauv av (xws li cov cim tawm hauv av, thiab cov zis tawm hauv cov khoom siv sib txawv thiab cov ntaub ntawv raug rho tawm ntawm cov ntaub ntawv sib kis thiab kev ruaj ntseg
Vim li cas 90% ntawm cov teeb meem tsis tuaj yeem ua tsis muaj cov cim liab?
Kuv yuav piav peb yam vim li cas thiaj li muaj lub cim cais tawm.
Thaiv hauv av voj kev cuam tshuam
Nyob rau hauv ntev-deb kev hloov pauv cable, qhov sib txawv hauv av muaj peev xwm ntawm cov khoom sib txawv tuaj yeem tsim kom muaj kev sib cuam tshuam txog kev sib cuam tshuam ntawm vens ntawm vens. Kev faib tawm cov suab nrov los ntawm kev hla lub suab nrov los ntawm kev sib cais ntawm 2500V DC, xws li Phoenix Mini MPR koob.
Txhim Kho Kev Ruaj Ntseg
Hauv cov chaw muaj kev phom sij xws li kev lag luam petrochemical, kev tiv thaiv kev tiv thaiv plc / dcs los ntawm high-voltage surges los yog xob laim (i6 {1}} ua raws).
Kev hloov pauv teeb tsis hloov
Nws txhawb 4-20 ma↔ 0-10 v, thermocouple hloov pauv thiab lwm cov khoom hla (xws li Omron K3hb-xvd series).
Dab tsi yog cov ntawm cov cim liab cais yog dab tsi?
Lub teeb liab colators tuaj yeem faib ua ntau hom raws li kev tsim kho hluav taws xob, thiab kuv yuav qhia cov hom teeb liab uas muaj peb txoj kev no.
Faib raws li hom kev siv hluav taws xob
1) passive teeb liab mis nyuj:Tsis tas yuav muaj lub zog hluav taws xob sab nraud, thiab yog tsav los ntawm nws lub zog los ntawm cov teeb liab tawm, uas haum rau qhov yooj yim, cov khoom siv tsawg-sz {2}} MS1 qauv).
2) Cov teeb meem tseemceeb:Nws yuav tsum tau muab hluav taws xob muab hluav taws xob sab nraud, txhawb nqa teeb liab kev ua kom sov thiab ua kom haum rau kev sib kis tau nrawm thiab ntev ntev (xws li BM100).
Faib raws li kev sib tw hom
1) Ob-Hlau System: Tsuas yog cov kab hluav taws xob thiab kab teeb liab yuav tsum muaj, nrog tus nqi qis tab sis ib yam muaj nuj nqi.
2) Peb-xaim / plaub-xaim: Txoj cai muaj zog ywj pheej thiab ntau lub teeb liab channel tsim txhim kho kev ruaj khov thiab kev tiv thaiv kev cuam tshuam, haum rau ntau hom kev sib koom tes sib koom tes.
Cov Qauv Ua Qauv Tshwj Xeeb
1) USB rho tawm(piv txwv li USB-ISO): Siv los cais kho lub computer USB chaw nres nkoj los ntawm kev cuam tshuam rau cov khoom lag luam hauv av kom tiv thaiv kom tsis txhob muaj kev cuam tshuam rau hauv av.
2) Ntau pua-channel mis nyuj(piv txwv li, MTL4600): Txhawb kev txhawb nqa analog, tawm, thiab digital teeb liab kev ua, haum rau kev tswj hwm kev tswj cov tshuab.
Yuav ua li cas xaiv cov teeb liab colilator uas haum rau koj cov kev xav tau?
Xaiv ib qho teeb liab colilator yog qhov teeb meem nyuaj, tab sis raws li lub cim kev cais cais cov chaw muag khoom, peb pab pawg ntawm cov txheej txheem xaiv, thiab tam sim no kuv yuav muab nws tam sim no qhia rau koj.
Kev cais tawm kev xaiv:
Optocouder Cais: Tus nqi tsawg, haum rau cov cim tsawg zaus (<1kHz), but low withstand voltage (≤3kV).
Magnetically Coupler cais: Kev sib kis tau kub (mus txog 150Mbps), kev tawm tsam muaj zog tiv thaiv, haum rau inverter scarios (xws li ADI Adum Adum Series).
Electromagnetic Raug Kho: withstand voltage txog 5kV (xws li puls ct series), haum rau cov chaw muaj kev pheej hmoo xws li lub tshuab hluav taws xob.
Kev cim phiajcim hom:
Analog teeb liab:{{0 {0}} ma / {{1} v Yuav kom tus neeg cais nrog Hart raws tu me nyuam (piv txwv li, MTL5041).
Cov cim digital:Rs {-485 / tuaj yeem yuav tsheb npav yuav tsum tau ua tiav kev tiv thaiv kev tiv thaiv (piv txwv li TI ISO3082).
Ib puag ncig kev yoog:
Kev Kub Siab Rhiav:Xaiv cov qauv Industrial-qib nrog kev ua haujlwm kub ntawm -40 degree ~ 85 degree (xws li wago {3}}).
Ntub dej:Cov Chav Tiv Thaiv IP67 + Coated PCB tsim (piv txwv li Phoenix 2903275).
