Kev tsim cov hlwb tuaj yeem sib txawv los ntawm hom cov teeb liab tso tawm (pneumatic, hydraulic, hluav taws xob) lossis cov qauv ntawm kev ntsuas qhov hnyav (bending beam, shear beam, siab, nro, thiab lwm yam).
Lub tshuab hluav taws xob hydraulic yog lub zog ntsuas qhov ntsuas qhov hnyav los ntawm kev hloov pauv ntawm lub siab ntawm cov kua ntim rau hauv. Nyob rau hauv ib tug dov diaphragm hydraulic load cell, lub load los yog quab yuam ua nyob rau hauv lub accumulator yog pauv mus rau lub piston, uas nyob rau hauv lem compresses lub filling kua nyob rau hauv lub elastic diaphragm kab noj hniav. Lub zog ntau dua, qhov siab dua ntawm cov kua dej hydraulic. Tus nqi siab no tuaj yeem qhia hauv zos lossis xa mus rau lwm qhov chaw rau kev taw qhia chaw taws teeb lossis tswj. Cov zis muaj ib tug linear yam ntxwv thiab yog kuj insensitive rau lub ntim thiab kub ntawm cov kua filling. Yog hais tias lub load hlwb raug ntsia thiab calibrated kom raug, lawv yog nyob rau hauv 0.25 feem pua ntawm tag nrho cov teev thiab yog haum rau feem ntau cov txheej txheem hnyav daim ntawv thov. Txij li thaum lub sensor no siv tsis muaj hluav taws xob Cheebtsam, nws yog qhov zoo tagnrho rau siv nyob rau hauv qhov chaw muaj kev phom sij. Hom hydraulic load cell daim ntaub ntawv muaj xws li tank, thawv thiab hopper hnyav. Rau qhov tseeb tshaj plaws, lub xov tooj ntawm tes yuav tsum tau muab tso rau ntawm txhua qhov kev txhawb nqa ntawm lub tank, thiab tag nrho qhov hnyav ntawm lub tank yuav tsum tau txais los ntawm kev suav cov txiaj ntsig ntawm cov sensors no.
Pneumatic load cells kuj tseem siv lub zog sib npaug. Cov khoom siv no siv ntau lub damping chamber kom ua tiav qhov tseeb dua li cov khoom siv hydraulic. Hauv qee qhov kev tsim, thawj damping chamber ua raws li tare chamber. Pneumatic load hlwb feem ntau siv hauv kev lag luam uas kev huv thiab kev nyab xeeb yog qhov tseem ceeb thiab ntsuas qhov hnyav me me. Insensitivity rau qhov kub thiab txias hloov thiab muaj peev xwm tawg-pov thawj muaj peev xwm yog ob qhov zoo ntawm hom load cell. Tsis tas li ntawd, txawm tias lub diaphragm ruptures, cov kua hauv nws yuav tsis ua rau muaj kab mob. Qhov tsis zoo yog tias nws qeeb qeeb thiab yuav tsum tau huv, qhuav txias cua lossis nitrogen.
Ib qho strain gage load cell hloov cov load ua rau nws mus rau hauv lub teeb liab hluav taws xob. Cov ntsuas ntsuas raug khi rau cov kab teeb lossis cov tswv cuab uas deform thaum thauj khoom. Feem ntau, qhov siab tshaj plaws rhiab heev thiab qhov kub thiab txias tau txais kev siv plaub hom gages. Feem ntau ob hom kab mob yog siv los ntsuas qhov nro thiab ob qho tib si siv los ntsuas qhov siab, thiab cov strain gages txuas rau ib leeg rau kev hloov kho. Thaum loaded, qhov kev ntxhov siab vim kev hloov hauv gage kuj yog proportional rau lub load. Raws li qhov tseeb ntawm strain gage load hlwb txuas ntxiv txhim kho thiab cov nqi tsev tseem pheej poob qis, lwm lub cell load tau maj mam thim tawm ntawm theem ntawm keeb kwm.
