Hauv kev tsim khoom lag luam, cov hlwb thauj khoom siv dav siv los ntsuas qhov hnyav ntawm cov khoom. Txawm li cas los xij, qhov tseeb ntawm lub xov tooj ntawm tes yog qhov tseem ceeb hauv kev ntsuas nws qhov kev ua tau zoo. Qhov tseeb yog hais txog qhov sib txawv ntawm qhov ntsuas qhov tso tawm tus nqi thiab tus nqi yuav tsum tau ntsuas, thiab yog raws li cov yam ntxwv xws li kev ntseeg siab thiab kev ruaj ntseg. Yog li ntawd, tsab xov xwm no yuav tham txog qhov tseeb ntawm lub load cell thiab nws daim ntawv thov.
Dab tsi yog qhov tseeb ntawm lub load cell?
Qhov tseeb ntawm lub sensor yog hais txog qhov sib txawv ntawm nws cov teeb liab tso zis thiab tus nqi yuav tsum tau ntsuas, feem ntau yog qhia raws li feem pua, hu ua qhov tseeb qhia qhov yuam kev (qhia qhov yuam kev). Precision indication yuam kev yog muab faib ua qhov ntau, feem pua thiab digital indication yuam kev. Hauv kev thauj khoom ntawm tes, qhov yuam kev ntau (qhov yuam kev ncaj qha lossis ncaj qha) yog hais txog qhov yuam kev los ntawm cov khoom xws li cov qauv kho vajtse, cov khoom siv tsis raug, kev tsim khoom, thiab lwm yam; Qhov feem pua yuam kev (los yog txheeb ze yuam kev) yog hais txog qhov yuam kev ntawm qhov sib piv ntawm lub sensor tso zis thiab tus nqi tiag tiag; Digital yuam kev yog hais txog qhov tseeb yuam kev uas ua los ntawm kev suav digital (xws li AD converter).
Cov yam ntxwv cuam tshuam qhov tseeb ntawm Load Cells
Mechanical misalignment: Thaum lub sij hawm sensor over-operation, mechanical misalignment yog ib qho ua rau poob ntawm qhov tseeb sensor. Qhov ua rau muaj kev tsis sib haum xeeb xws li lub cev deformation, kev txhim kho corrosion, tsis yog tus qauv, thiab lwm yam.
Kev Ua Teeb Meem Tsis Zoo: Cov teeb liab suab nrov uas siab dhau lossis qis dhau tuaj yeem cuam tshuam rau qhov tso tawm ntawm lub sensor. Qhov ua rau ntawm qhov tsis zoo no suav nrog kev tsim qauv me me dhau, teeb liab ua Circuit Court poob lossis tsis zoo, thiab lwm yam.
Environmental yam: Load cells yog siv nyob rau hauv ib puag ncig tej yam kev mob sib txawv, thiab txawv ib puag ncig tej yam kev mob yuav cuam tshuam rau kev ua tau zoo ntawm lub load cell. Xws li kev hloov pauv kub, ua haujlwm lub neej, siv ib puag ncig, thiab lwm yam.
Kev txhim kho ntawm Load Cell raug
Xaiv qhov tsim nyog sensor: Ua ntej ntawm tag nrho cov, koj yuav tsum xaiv qhov tsim nyog load cell qauv raws li daim ntawv thov scenario tiag tiag kom tau txais qhov ntsuas qhov hnyav dua.
Ua tib zoo xaiv cov ntawv thov ib puag ncig: Thaum txhim kho thiab siv lub tshuab thauj khoom, yuav tsum tau them nyiaj rau kev cuam tshuam ntawm ntau yam ib puag ncig xws li ambient kub thiab txhua yam hnav ntawm qhov tseeb ntawm lub xov tooj ntawm tes. Qee cov qauv thiab kev siv tsim nyog yuav tsum tau ua raws li, xws li tsis txhob muaj qhov kub thiab txias ib puag ncig.
Instrument Calibration: Kev ntsuas kom zoo tuaj yeem txhim kho qhov tseeb ntawm lub xov tooj ntawm tes. Calibration ua kom lub sensor teb cov yam ntxwv, rhiab heev thiab stability. Laboratory calibration yog muab kev ntsuas qhov tseeb ntawm load cell raug thiab txhim kho kev ntseeg siab ntawm load cell calibration.
Nyob rau hauv xaus
Qhov tseeb ntawm lub xov tooj ntawm tes yog qhov tseem ceeb rau kev ntsuas qhov tseeb ntawm nws cov cuab yeej. Ib qho kev ntsuas xws li kev txhim kho kev ruaj ntseg ntawm cov cuab yeej, txo cov cuab yeej kev co, thiab kev txhim kho ib puag ncig tuaj yeem txhim kho qhov tseeb ntawm lub xov tooj ntawm tes. Kev khiav hauj lwm xws li calibration tuaj yeem ua kom ntseeg tau tias lub xov tooj ntawm tes tuaj yeem ua haujlwm txuas ntxiv kom raug.
