Modulating tswj, teb- kho tau xoom/span/gain; txhawb nqa ncaj qha lossis thim rov qab |
|
Kev ua tau zoo |
Tsawg hysteresis (≈ 0.6% tso zis ncua), rov ua tau zoo thiab cov lus teb ruaj khov tshaj qhov sib txawv ntawm cov khoom siv. |
Aqhov zoo
Precise Positioning:Tsawg hysteresis tsim (kwv yees li 0.6% ntawm cov zis ntau) txo qhov kev sib txawv ntawm lub valve thiab txhim kho cov txheej txheem tswj kev ruaj ntseg.
Teb ceev ceev:Cov zis siab tuaj yeem ncav cuag cov khoom siv siab (tsawg dua lossis sib npaug li 150 psig), nrog dual -kawg synchronous tswj kom nrawm dua thiab muaj zog dua.
Strong Compatibility:Txhawb nqa tus qauv 4-20 mA cov teeb liab, ncaj qha sib xws nrog lub hauv paus DCS / PLC systems, txo cov nqi kev koom ua ke.
Flexible Adjustment:Txhawb xoom-point, ntau yam, thiab tau txais kev hloov kho, thiab tuaj yeem hloov pauv ntawm qhov ncaj qha thiab thim rov qab ua kom tau raws li kev ua haujlwm sib txawv.
Daim ntawv thov
Petrochemical kev lag luam:Siv rau kev khiav dej num thiab kev tswj xyuas kom txhim kho cov txheej txheem stability.
Lub zog system:Siv rau chav dej thiab kev tswj xyuas dej kom ntseeg tau tias cov cuab yeej siv tau zoo.
Natural gas kis:Siv rau kev tswj siab los txhim kho cov kav dej kom ruaj khov.
Kev kho dej:Siv rau kev khiav thiab qib kev tswj xyuas kom muaj kev kho mob tas mus li.
