Peb txhua tus paub tias lub hauv paus tseem ceeb ntawm kev ntsuas hluav taws xob yog qhovload cell, uas yog hu ua "lub plawv" ntawm ib qho hluav taws xobnplai. Nws tuaj yeem hais tau tias qhov tseeb thiab rhiab heev ntawm lub sensor ncaj qha txiav txim siab qhov ua tau zoo ntawm cov nplai hluav taws xob. Yog li yuav ua li cas peb xaiv lub load cell? Rau peb cov neeg siv dav dav, ntau qhov tsis zoo ntawm lub xov tooj ntawm tes (xws li nonlinearity, hysteresis, creep, kub them nyiaj ntau, rwb thaiv tsev, thiab lwm yam) yeej ua rau peb ntxhov siab heev. Cia peb saib cov yam ntxwv ntawm lub ntsuas hluav taws xob ntsuas hluav taws xob txog tnws lub ntsiab technical parameters.
(1) Rated load: qhov siab tshaj plaws axial load uas lub sensor tuaj yeem ntsuas nyob rau hauv qhov kev ntsuas qhov ntsuas tau teev tseg. Tab sis nyob rau hauv kev siv tiag tiag, feem ntau tsuas yog 2/3 ~ 1/3 ntawm qhov ntsuas ntau yog siv.
(2) Tso cai thauj khoom (lossis muaj kev nyab xeeb tshaj): qhov siab tshaj plaws axial load tso cai los ntawm lub xov tooj ntawm tes. Kev ua haujlwm dhau los raug tso cai nyob rau hauv ib qho chaw. Feem ntau 120% ~ 150%.
(3) Txwv tsis pub thauj khoom (lossis txwv tsis pub dhau): qhov siab tshaj plaws axial load uas lub ntsuas hluav taws xob tuaj yeem dais yam tsis ua rau nws poob nws lub peev xwm ua haujlwm. Qhov no txhais tau hais tias lub sensor yuav raug puas tsuaj thaum ua haujlwm tshaj qhov nqi no.
(4) rhiab heev: qhov sib piv ntawm cov zis increment rau cov ntaub ntawv load increment. Feem ntau mV ntawm cov zis tso zis ib 1V ntawm cov tswv yim.
(5) Nonlinearity: Qhov no yog qhov ntsuas qhov tseeb ntawm kev sib raug zoo ntawm cov teeb liab tawm hluav taws xob los ntawm hluav taws xob ntsuas hluav taws xob thiab cov khoom thauj.
(6) Repeatability: Repeatability qhia seb tus nqi tso tawm ntawm lub sensor tuaj yeem rov ua dua thiab zoo ib yam thaum tib lub thauj khoom tau siv ntau zaus hauv tib lub sijhawm. Cov yam ntxwv no tseem ceeb dua thiab tuaj yeem cuam tshuam qhov zoo ntawm lub sensor. Cov lus piav qhia ntawm qhov yuam kev repeatability hauv lub teb chaws tus qauv: qhov kev ua yuam kev repeatability tuaj yeem ntsuas nrog cov nonlinearity tib lub sijhawm raws li qhov sib txawv siab tshaj plaws (mv) ntawm qhov tseeb tso tawm teeb liab qhov tseem ceeb ntsuas peb zaug ntawm tib lub ntsuas ntsuas.
(7) Lag: Lub ntsiab lus nrov ntawm hysteresis yog: thaum lub load yog thov mus rau ib kauj ruam thiab ces unloaded nyob rau hauv lem, coj mus rau txhua lub load, lub hom phiaj yuav tsum muaj tib nyeem ntawv, tab sis qhov tseeb nws yog zoo ib yam, cov degree ntawm inconsistency. yog xam los ntawm hysteresis yuam kev. qhov taw qhia los sawv cev. Qhov yuam kev hysteresis yog xam nyob rau hauv lub teb chaws tus qauv raws li hauv qab no: qhov siab tshaj plaws qhov sib txawv (mv) nruab nrab ntawm tus lej lej ntawm qhov tseeb tso zis teeb liab tus nqi ntawm peb lub strokes thiab tus lej lej ntawm qhov tseeb tso zis teeb liab tus nqi ntawm peb lub upstrokes ntawm tib qhov kev sim. taw tes.
(8) Creep thiab creep rov qab: Qhov yuam kev nkag ntawm lub sensor yuav tsum tau kuaj xyuas los ntawm ob yam: ib qho yog creep: qhov ntsuas load yog siv yam tsis muaj kev cuam tshuam rau 5-10 vib nas this, thiab 5-10 vib nas this tom qab thauj khoom. Siv cov ntawv nyeem, tom qab ntawd sau cov txiaj ntsig tso tawm ua ntu zus nyob rau lub sijhawm tsis tu ncua hauv 30 feeb. Qhov thib ob yog creep rov qab: tshem tawm cov ntsuas load kom sai li sai tau (hauv 5-10 vib nas this), nyeem tam sim hauv 5-10 vib nas this tom qab tshem tawm, thiab tom qab ntawd sau cov nqi tso tawm ntawm qee lub sijhawm nyob rau hauv 30 feeb.
(9) Tso cai siv qhov kub thiab txias: qhia txog lub sijhawm siv tau rau lub xov tooj ntawm tes no. Piv txwv li, qhov ntsuas kub ib txwm muaj feem ntau cim li: -20℃- +70℃. Qhov kub thiab txias sensors yog cim raws li: -40°C - 250°C.
(10) Kub them nyiaj ntau: Qhov no qhia tau hais tias lub sensor tau raug them nyiaj raws li qhov kub thiab txias thaum lub sijhawm tsim khoom. Piv txwv li, qhov ntsuas kub ib txwm muaj feem ntau cim li -10°C - +55°C.
(11) Rwb thaiv tsev tsis kam: cov nqi hluav taws xob tiv thaiv hluav taws xob ntawm qhov hluav taws xob hluav taws xob ntawm lub ntsuas hluav taws xob thiab cov nqaj elastic, qhov loj dua qhov zoo dua, qhov loj ntawm cov rwb thaiv tsev yuav cuam tshuam rau kev ua haujlwm ntawm lub sensor. Thaum lub rwb thaiv tsev tiv thaiv qis dua ib qho nqi, tus choj yuav tsis ua haujlwm zoo.
