Vim li cas kuv thiaj yuav tsum paub txog load cells?
Load cells yog nyob rau hauv lub plawv ntawm txhua qhov ntsuas thiab ua kom cov ntaub ntawv hnyav niaj hnub ua tau. Load cells tuaj nyob rau hauv ntau hom, qhov ntau thiab tsawg, muaj peev xwm thiab cov duab raws li cov ntawv thov uas siv lawv, yog li nws tuaj yeem yooj yim thaum koj thawj zaug kawm txog cov hlwb. Txawm li cas los xij, kev nkag siab cov hlwb yog thawj kauj ruam tsim nyog hauv kev nkag siab txog cov peev txheej ntawm txhua hom thiab cov qauv ntawm cov nplai. Ua ntej, kawm paub yuav ua li cas thauj cov hlwb ua haujlwm nrog peb cov lus piav qhia luv luv, tom qab ntawd kawm 10 qhov tseeb ntawm cov kabmob thauj khoom - pib nrog lub tshuab thauj khoom ntawm tes mus rau ntau daim ntawv thov sib txawv koj tuaj yeem siv lawv hauv!
10 Qhov tseeb
1. Lub plawv ntawm txhua qhov ntsuas.
Lub load cell yog qhov tseem ceeb tshaj plaws ntawm qhov ntsuas qhov system. Yog tias tsis muaj lub cev thauj khoom, lub ntsuas ntsuas tsis tuaj yeem ntsuas qhov kev hloov pauv ntawm lub zog los ntawm kev thauj khoom lossis qhov hnyav. Lub load cell yog lub plawv ntawm txhua qhov ntsuas.
2. Lub hauv paus chiv keeb.
Load cell technology hnub rov qab mus rau 1843, thaum British physicist Charles Wheatstone tsim ib tug hluav taws xob choj Circuit Court los ntsuas hluav taws xob tsis kam. Nws hu ua lub thev naus laus zis tshiab no Wheatstone tus choj, uas tseem siv niaj hnub no los ua lub hauv paus rau kev thauj khoom ntawm tes ntsuas ntsuas.
3. Kev siv tsis kam.
Cov ntsuas ntsuas siv qhov kev xav ntawm kev tawm tsam. Ib lub tshuab ntsuas kab mob muaj cov xaim nyias nyias uas yog woven rov qab los rau hauv ib daim phiaj zigzag kom ua tau zoo ntev ntawm cov hlau thaum siv quab yuam. Cov hlau no muaj ib qho kev tiv thaiv. Thaum lub load yog thov, cov hlau stretches los yog compresses, yog li nce los yog txo nws cov kuj - peb ntsuas qhov tsis kam los txiav txim qhov hnyav.
4. Kev ntsuas ntau yam.
Load cells tuaj yeem ntsuas ntau dua li lub zog cantilever, lossis lub zog tsim tawm ntawm ib kawg ntawm lub xov tooj ntawm tes. Qhov tseeb, lub hlwb thauj khoom tuaj yeem ntsuas qhov tsis kam rau ntsug compression, nro thiab txawm tias raug tshem tawm.
5. Peb pawg loj.
Load cells poob rau hauv peb pawg loj: Environmental Protection (EP), Welded Sealed (WS) thiab Hermetically Sealed (HS). Paub seb hom load cell twg koj xav tau yuav ua tau zoo sib xws ntawm lub xov tooj ntawm tes rau koj daim ntawv thov thiab yog li ua kom cov txiaj ntsig zoo tshaj plaws.
6. Qhov tseem ceeb ntawm deflection.
Deflection yog qhov kev ncua deb ntawm lub xov tooj ntawm tes khoov los ntawm nws qhov chaw so qub. Deflection yog tshwm sim los ntawm lub zog (load) siv rau lub load cell thiab tso cai rau lub strain gauge ua nws txoj hauj lwm.
7. Load cell thaiv.
Load cell thaiv excitation, teeb liab, shielding thiab sensing xim ob peb ua ke yuav dav heev, thiab txhua lub chaw tsim tshuaj paus tab tom tsim lawv tus kheej wiring xim ua ke.
8. Custom scale daws.
Koj tuaj yeem ua ke cov khoom thauj mus rau hauv cov qauv uas twb muaj lawm xws li hoppers, tanks, silos thiab lwm lub thawv los tsim cov kev daws teeb meem. Cov no yog cov kev daws teeb meem zoo tshaj plaws rau cov ntawv thov uas xav tau kev tswj hwm cov khoom muag, daim ntawv qhia batching, cov khoom siv thauj khoom, lossis xav kom sib sau ua ke rau hauv cov txheej txheem tsim.
9. Load cell thiab raug.
Kev ntsuas qhov tseeb siab feem ntau suav hais tias muaj qhov yuam kev ntawm ± 0.25% lossis tsawg dua; tsawg dua cov tshuab yuav muaj qhov yuam kev ntawm ±.50% lossis ntau dua. Txij li feem ntau qhov ntsuas qhov hnyav feem ntau muaj qhov yuam kev ± 0.01%, lub hauv paus ntawm qhov yuam kev ntawm qhov ntsuas yuav yog lub xov tooj ntawm tes thiab, qhov tseem ceeb tshaj, kev kho tshuab ntawm qhov ntsuas nws tus kheej.
10. Txoj cai load cell rau koj.
Txoj hauv kev zoo tshaj plaws los tsim kom muaj qhov ntsuas qhov ntsuas siab tshaj plaws yog xaiv txoj cai thauj khoom ntawm tes rau koj daim ntawv thov. Nws tsis yog ib txwm yooj yim kom paub qhov twg lub xov tooj ntawm tes yog qhov zoo tshaj plaws rau txhua daim ntawv thov tshwj xeeb. Yog li ntawd, koj yuav tsum ib txwm engineer thiab load cell kws.
