Peb cov ntsuas hluav taws xob DC sib xyaw ua ke txhua tus siv ib qho ua - hauv shunt los ua piv txwv tam sim no. Kuv ntseeg tias ntau ntawm peb cov phooj ywg thiab cov neeg siv khoom, zoo li kuv tus kheej, kuj tsis paub nrog TMR sensors. Niaj hnub no, raws li cov ntaub ntawv los ntawm tag nrho hauv internet, kuv yuav piav qhia ob lo lus nug tseem ceeb hauv cov ntsiab lus yooj yim: TMR yog dab tsi? Puas muaj TMR sensor DC zog ntsuas ntawm lub khw?
I. Kev piav qhia yooj yim: TMR Sensor yog dab tsi?
TMR stands rau Tunnel Magnetoresistance. Cias muab, nws yog siab -precision magnetic sensor raws li magnetoelectronics. Nws cov thev naus laus zis thev naus laus zis siv nanoscale sandwich qauv ntawm ferromagnetic txheej / tsis yog-magnetic insulating txheej / ferromagnetic txheej, ua tiav cov kev hloov pauv ntawm cov cim sib nqus rau cov teeb liab hluav taws xob los ntawm electron spin.
Piv nrog rau cov cuab yeej siv tshuaj ntsuam xyuas ib txwm muaj, qhov zoo tshaj plaws ntawm TMR sensors yog siab rhiab heev, tsis muaj zog siv, me me, thiab kev ua haujlwm ruaj khov. Lawv tsuas xav tau ib qho me me sab nraud magnetic teb kom ua tiav cov kev hloov pauv tseem ceeb hauv kev tiv thaiv, raug ntes cov cim tsis muaj zog sib nqus. Tam sim no, lawv tau maj mam siv rau hauv thaj chaw xws li tsis yog - kev kuaj kev puas tsuaj, aerospace, thiab ntsuas hluav taws xob.
Nyob rau hauv daim ntawv thov scenarios ntawm DC lub zog ntsuas, TMR sensors tuaj yeem hloov cov tsoos shunts thiab Hall sensors kom ua tau siab -kev ntsuas qhov tseeb ntawm DC tam sim no, ua rau lawv tshwj xeeb tshaj yog haum rau cov xwm txheej uas yuav tsum muaj siab rau qhov loj me, kev siv hluav taws xob, thiab ntsuas qhov tseeb.
II. Kev Lag Luam Status: Puas muaj TMR sensor DC lub zog ntsuas ntawm lub khw?
Cov lus teb yog: kab tias, tab sis nws yog ib qho lag luam niche heev.
Raws li kev tshawb fawb hauv online, tam sim no tsuas yog cov tuam txhab tsawg heev hauv Suav teb tau ua tiav kev lag luam- nplai daim ntawv thov ntawm TMR thev naus laus zis, suav nrog TMR tam sim no sensor modules, uas tuaj yeem siv rau kev ntsuas tam sim no hauv DC lub zog ntsuas. Tsis tas li ntawd, qee lub tuam txhab kuj tau ua tiav TMR thev naus laus zis cov khoom lag luam, muab kev txhawb nqa tseem ceeb rau cov tuam txhab ntsuas hluav taws xob cuam tshuam.
Txawm li cas los xij, los ntawm kev ua lag luam tag nrho, TMR sensor DC lub zog ntsuas hluav taws xob tseem nyob rau theem niche. Feem ntau cov tuam txhab lag luam (xws li UBS Electronics) tam sim no siv ua - nyob rau hauv shunt tam sim no sampling nyob rau hauv lawv mainstream DC zog ntsuas - txoj kev no yog technically mature, tus nqi - tswj tau, thiab muab metering ruaj khov, ua tau raws li cov kev xav tau ntawm feem ntau industrial, photovoltaic, thiab lub zog cia scenarios.
III. Kev piav qhia ntxiv: Qhov sib txawv ntawm qhov sib txawv ntawm Shunt Units thiab TMR Sensors (Simplified Version)
Ntau tus neeg siv khoom xav paub, vim tias ob qho tib si yog cov khoom siv ntsuas tam sim no, qhov txawv ntawm lawv yog dab tsi? Ib lub rooj tuaj yeem paub qhov txawv sai sai:
| Sib piv Dimension | Ua -hauv Flow Splitter (Mainstream) | TMR Sensor (Niche & High{0}}kawg) |
|---|---|---|
| Core Zoo | Mature technology, tus nqi qis, ruaj khov metering | High rhiab heev, tsawg zog noj, me me |
| Daim ntawv thov Scenario | Kev lag luam zoo ib yam, PV zog cia thiab lwm yam xwm txheej | High - ntsuas qhov tseeb, cov khoom siv me me, ib puag ncig tshwj xeeb |
| Kev Ua Lag Luam Kev Lag Luam | Siab heev, saws los ntawm feem coob ntawm manufacturers | Tsawg heev, tsis muaj chaw tsim khoom lag luam tau tshaj tawm cov khoom lag luam tseem ceeb |
Hauv kev xaus
TMR sensors yog hom tshiab ntawm siab -precision, siab -kev ua tau zoo sib nqus sensor. Thaum tej zaum yuav muaj ob peb TMR sensor DC lub zog ntsuas ntawm kev ua lag luam, lawv tsis zoo li yuav dhau los ua qhov tseem ceeb.
Tsis tas li ntawd, rau daim ntawv thov DC metering tam sim no, DC lub zog ntsuas hluav taws xob nrog ua -hauv shunts (xws li peb cov DC lub zog ntsuas hluav taws xob los ntawm UBS Electronics, uas nws qhov kev tswj xyuas sab hauv yog yuav luag ib txwm nyob hauv 0.2 chav kawm) tuaj yeem ua tau raws li qhov yuav tsum tau ua thiab muab cov nqi zoo dua -kev ua tau zoo.
