Leonardo Da Vinci akashandisa zvinzvimbo zveakaremerwa counterweights pane mechaniki lever kuyera uye kuona huremu husingazivikanwe. Kusiyana kwemagadzirirwo ake akashandisa marevheti akawanda, imwe neimwe yehurefu hwakasiyana uye yakaenzana nehuremu humwe chete. Pamberi pe hydraulic uye yemagetsi strain gauge mutoro maseru akatsiva ma mechanic levers ekuyera maindasitiri maapplication, aya ma mechanic lever zviyero aishandiswa zvakanyanya. Dzaishandiswa kuyera zvinhu zvose kubva kumapiritsi kusvika kumotokari dzenjanji uye dzakazviita nemazvo uye zvakavimbika chero dzaive dzakakwenenzverwa uye dzakachengetwa. Vaisanganisira kushandiswa kwehuremu hwekuenzanisa kana kuonekwa kwesimba rakagadzirwa nemagetsi emagetsi. Yekutanga, pre-strain gage force sensors yaisanganisira hydraulic uye pneumatic dhizaini.
Muna 1843, nyanzvi yefizikisi yekuBritain Charles Wheatstone akagadzira dunhu rebhiriji raikwanisa kuyera kupikisa kwemagetsi. Iyo Wheatstone bhiriji reketi yakanakira kuyera shanduko yekudzivirira inoitika mumageji ekunetsa. Kunyangwe iyo yekutanga yakasungirirwa yekupokana newaya strain gage yakagadziridzwa muma1940s, hazvina kusvika kusvika magetsi emazuva ano abatwa kuti tekinoroji nyowani yave kugona uye nehupfumi. Kubva panguva iyoyo, zvakadaro, mageji ekumanikidza akawedzera ese ari maviri semakiniki zviyero uye mumaseru ekumira-oga. Nhasi, kunze kwekune mamwe marabhoritari uko kuchiri kushandiswa chaiko, maseru anorema gage anotonga indasitiri yekuyera. Pneumatic mutoro maseru dzimwe nguva anoshandiswa uko kuchengetedzeka kwemukati uye hutsanana hunodiwa, uye hydraulic mutoro maseru anotariswa munzvimbo dziri kure, sezvo asingade magetsi. Strain gage mutoro maseru anopa chokwadi kubva mukati me 0.03% kusvika 0.25% yakazara chiyero uye akakodzera kunenge ese maindasitiri ekushandisa.
