ASero rekutakuraimhando yetransducer kana sensor inoshandura simba kuita magetsi anobuda. Mudziyo wako we load cell une magauge mana ekukwesha muchimiro chebhiriji regorosi. Muchikamu chemaindasitiri, shanduko iyi inosanganisira load inoshandurwa kuita chiratidzo chemagetsi cheanalog.
Leonardo Da Vinci akashandisa nzvimbo dzezviyero zvinochinjika zvakagadziriswa pachigadziko chemagetsi kuti aenzane uye aone huremu husingazivikanwe. Kuchinja-chinja kwemagadzirirwo ake kwaishandisa zviyero zvakawanda, chimwe nechimwe chine hurefu hwakasiyana uye chakaenzaniswa nehuremu humwe chete. Masero emagetsi asati atora nzvimbo dzezviyero zvemagetsi zvekushandisa pakuyera uremu mumaindasitiri, zviyero izvi zvezviyero zvemagetsi zvaishandiswa zvakanyanya. Zvaishandiswa kuyera zvese kubva pamapiritsi kusvika kumotokari dzechitima uye zvaiitwa nemazvo uye zvakavimbika chero bedzi zvaigadziriswa zvakanaka uye zvichichengetwa. Zvaisanganisira kushandiswa kwenzira yekuenzanisa huremu kana kuona simba rakagadzirwa nezvigadzirwa zvemagetsi. Masensa ekutanga, epre-strain gage force aisanganisira dhizaini yehydraulic nepneumatic.
Muna 1843, nyanzvi yefizikisi yekuBritain Charles Wheatstone akagadzira dunhu rebhiriji raigona kuyera kusimba kwemagetsi. Dunhu rebhiriji reWheatstone rakanakira kuyera shanduko dzekudzivirira dzinoitika mumageji ekusimba. Kunyangwe geji rekutanga rekudzivirira waya rakagadziriswa muma1940, tekinoroji itsva haina kusvika pakasvika magetsi emazuva ano apo tekinoroji itsva yakava inoshanda mune zvehunyanzvi uye mune zvemari. Kubva panguva iyoyo, zvisinei, mageji ekusimba awanda sezvikamu zvemakanika uye mumaseji ekutakura akazvimirira. Nhasi, kunze kwemamwe marabhoritari uko kuyera kwemakanika kwakanyatsogadzirwa kuchiri kushandiswa, maseji ekutakura estrain gage anotonga indasitiri yekuyera. Maseji ekutakura epneumatic dzimwe nguva anoshandiswa uko kuchengetedzeka kwemukati uye hutsanana zvinodiwa, uye maseji ekutakura ehydraulic anoonekwa munzvimbo dziri kure, sezvo asingade magetsi. Maseji ekutakura estrain gage anopa kururama kubva mukati me0.03% kusvika 0.25% yakazara uye akakodzera kushandiswa kwese kwemaindasitiri.
Inoshanda sei?
Magadzirirwo emaLoad cell anorongwa zvichienderana nerudzi rwechiratidzo chinobuda (pneumatic, hydraulic, electric) kana zvichienderana nenzira yaanoona nayo huremu (compression, tension, kana shear)HydraulicMasero ekutakura zvinhu zvinoshandiswa pakumanikidza, zvichiyera huremu sekuchinja kwekumanikidzwa kwemvura yemukati inozadza.PneumaticMasero ekutakura anoshandawo pasi pemutemo wekusimbisa simba. Midziyo iyi inoshandisa dampener yakawanda
makamuri kuti ape kururama kwakanyanya kupfuura mudziyo we hydraulic.Kuyera kushushikanaMasero ekutakura anoshandura mutoro unoshanda paari kuita masaini emagetsi. Mageji acho pachawo anosungirirwa padanda kana nhengo yechimiro iyo inoshanduka kana huremu hwashandiswa.
