10 yam me me kom paub txog load cells

Vim li cas peb yuav tsum paub txogload hlwb?
Load cells yog nyob rau hauv lub plawv ntawm txhua qhov ntsuas thiab ua kom cov ntaub ntawv hnyav niaj hnub ua tau. Muaj ntau ntau hom, qhov ntau thiab tsawg, muaj peev xwm, thiab cov duab ntawm cov kabmob thauj khoom raws li muaj cov ntawv thov uas lawv siv, yog li nws tuaj yeem yooj yim thaum koj thawj zaug kawm txog cov cell load. Txawm li cas los xij, kev nkag siab cov hlwb yog thawj kauj ruam tseem ceeb hauv kev nkag siab lub peev xwm 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 ceev txog cov kabmob thauj khoom - pib nrog lub tshuab thauj khoom ntawm tes thiab mus rau txhua txoj hauv kev mus rau ntau daim ntawv thov sib txawv koj tuaj yeem siv lawv rau!

10 yam me me kom paub
1. Qhov tseem ceeb ntawm txhua qhov ntsuas.
Lub load cell yog qhov tseem ceeb tshaj plaws ntawm qhov ntsuas qhov system. Yog tias tsis muaj lub xov tooj ntawm tes, lub ntsuas ntsuas tsis tuaj yeem ntsuas 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 choj Circuit Court los ntsuas tsis kam. Nws tau hu ua cov thev naus laus zis tshiab no tus choj Wheatstone, uas tseem siv los ua lub hauv paus rau kev thauj khoom ntawm tes ntsuas ntsuas hnub no.

3. Siv cov resistors.
Cov kab ntsuas ntsuas siv qhov ntsuas qhov ntsuas tsis kam. Ib qho kev ntsuas ntsuas muaj ib txoj hlua 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 tsis kam - peb ntsuas qhov tsis kam los txiav txim qhov hnyav.

4. Ntsuas kev sib txawv.
Load cells muaj peev xwm ntsuas ntau dua li lub zog cantilever xwb, lossis lub zog tawm ntawm ib kawg ntawm lub xov tooj ntawm tes. Qhov tseeb, lub hlwb thauj khoom tuaj yeem ntsuas qhov kev tiv thaiv nyob rau hauv ntsug compression, nro thiab txawm raug tshem tawm nro.

5. Peb pawg loj.
Load cells tau muab faib ua peb pawg loj: Environmentally Protected (EP), Welded Sealed (WS) thiab Hermetic 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, 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 sensor thaiv.
Cov xim sib xyaw ua ke rau kev thauj khoom ntawm tes xov hlau excitation, teeb liab, tiv thaiv thiab kev hnov ​​​​qab tuaj yeem dav heev, nrog rau txhua tus neeg tsim khoom tsim lawv tus kheej thaiv cov xim sib txuas.

8. Customized 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 cov hlab ntsha los tsim cov kev cai ntsuas kev daws teeb meem. Cov no yog cov kev daws teeb meem zoo tshaj plaws rau cov ntawv thov uas xav tau kev tswj xyuas cov khoom muag, kev noj cov zaub mov, cov khoom siv thauj khoom lossis cov neeg uas nyiam ua ke qhov hnyav 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 system yuam kev ntawm ± .50% lossis ntau dua. Txij li feem ntau qhov ntsuas qhov hnyav feem ntau muaj qhov yuam kev ntawm ± 0.01%, qhov tseem ceeb ntawm qhov ntsuas qhov yuam kev yuav yog lub xov tooj ntawm tes thiab, qhov tseem ceeb tshaj, kev kho tshuab ntawm qhov ntsuas nws tus kheej.

10. Txoj caiload cellrau koj.
Txoj hauv kev zoo tshaj plaws los tsim kom muaj qhov ntsuas qhov ntsuas siab yog xaiv cov khoom thauj khoom zoo rau koj daim ntawv thov. Nws tsis yog ib txwm yooj yim kom paub tias 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 ua ib tug engineer thiab load cell kws.
