High lossis Saturated Output Signal |
1. Cov txheej txheem siab tshaj qhov ntau 2. Thaiv lossis khov impulse piping 3. Sensor lossis hluav taws xob tsis ua haujlwm |
1. Txheeb xyuas cov txheej txheem siab nyob rau hauv lub transmitter ntau yam 2. Tshawb xyuas thiab meej cov kav dej impulse, ntxiv rwb thaiv tsev yog tsim nyog 3. Recalibrate los yog hloov transmitter |
|
Tsis ruaj khov/Fluctuating Output |
1. Cov txheej txheem nrawm nrawm nrawm 2. Kev cuam tshuam hluav taws xob (tsis zoo hauv av, teeb meem cable) 3. Damping teeb qis dhau |
1. Nruab ib lub snubber los yog pulsation dampener ua ntej lub transmitter 2. Xyuas cable shielding thiab grounding, xyuas kom meej nws yog tsim nyog 3. Ua kom lub sij hawm damping kom tsim nyog ntawm HART communicator |
|
Kev nyeem tsis raug/Drift |
1. Zero lossis span drift 2. Cov nyhuv kub siab tshaj qhov tshwj xeeb 3. Kev puas tsuaj rau cov khoom siv los yog overpressure rau sensor |
1. Recalibrate xoom thiab ncua 2. Paub meej tias ambient thiab cov txheej txheem xov xwm kub yog nyob rau hauv qhov kev txwv 3. Kos rau overpressure xwm txheej, hloov transmitter yog tsim nyog |
|
HART Communicator Tsis Muaj Kev Sib Txuas Lus |
1. Lub voj tsis txaus (250Ω) 2. Kev xaim tsis raug lossis kev sib txuas tsis zoo 3. Cov khoom siv hluav taws xob qis qis 4. HART ntaus ntawv chaw nyob tsis sib haum |
1. Ntxiv ib 250Ω resistor nyob rau hauv series nyob rau hauv lub voj 2. xyuas tag nrho cov kev sib txuas ntawm cov hlua kom nruj 3. xyuas kom meej tias lub hwj chim mov voltage yog nyob rau hauv specification 4. xyuas seb HART ntaus ntawv chaw nyob yog teem rau 0. |
Rosemount 2088 Siab Transmitter - Qhov Zoo & Kev Ua Haujlwm Zoo
Qhov Zoo Tshaj Plaws
1. Tus nqi zoo heev -Kev ua tau zoo thiab kev them taus
· Raws li kev lag luam kev lag luam hauv Rosemount portfolio, 2088 muab tus nqi sib tw heev thaum tswj hwm kev ua tau zoo thiab kev ua tau zoo, ua rau nws zoo tagnrho rau kev siv nyiaj - nco qab daim ntawv thov.
2. Txhim khu kev ua tau zoo
· Muab kev ntsuas qhov tseeb (feem ntau ± 0.25%), txaus rau feem ntau kev lag luam kev siv xws li cov txheej txheem siab xyuas, twj tso kua mis tswj, thiab lim xyuas.
3. Rugged thiab Adaptive Design
· Features rugged cam khwb cia txhuas vaj tse rau kev tiv thaiv ib puag ncig zoo. Ntau yam txheej txheem kev sib txuas thiab kev xaiv foob tso cai rau nws hloov mus rau ntau yam kev lag luam ib puag ncig.
4. Yooj yim installation thiab tu
· Yooj yim tsim rau installation yooj yim. Calibration tuaj yeem ua tau los ntawm kev yooj yim - nkag ncua thiab xoom hloov kho, tsis tas yuav siv cov cuab yeej nyuaj lossis software, txo kev siv zog thiab sijhawm.
5. Daim ntawv pov thawj kev nyab xeeb thoob ntiaj teb
