I-sensor isetyenziselwa ukumisela ubunzima: ubunzima obuqhutywe yisampuli buguqulwa bube ngumqondiso wombane ngenzwa yokulinganisa. Ke ngoko, iseli yomthwalo licandelo lesikali sombane.

Itekhnoloji esetyenziswa ngokubanzi isekelwe kwi-teknoloji ye-strain gauge: i-analog yokulinganisa inzwa iqukethe into yokulinganisa (ebizwa ngokuba ngumzimba we-spring) eyenziwe ngetsimbi okanye i-aluminium, apho i-strain gauge (i-Wheatstone bridge) ifakwe khona. Isikali ngasinye se-elektroniki sineseli yomthwalo odibeneyo ukuqinisekisa ukuba ubunzima bunokulinganiswa.

Izinzwa zobunzima begeyiji yoxinzelelo zisetyenziswa ngokubanzi, kodwa kukho obunye ubuchwephesha bokulinganisa, obufana netekhnoloji yembuyekezo ye-electromagnetic force EMFC, ekugqitywe kuyo ngobunzima buqhutywa ngokupheleleyo ngaphandle kokulahleka kwefriction. Ngokuqhelekileyo, iiseli zomthwalo zifakwe kwiifektri, ezifana nokuzalisa izityalo, ukulinganisa iitanki, ukugqiba inani lokuzalisa, njl.

Zeziphi iindidi zezivamvo ezikhoyo?

Kukho iintlobo ezininzi zeeseli zomthwalo, kuxhomekeke kwiinjongo zabo zoyilo. Ukugoba umqadi okanye iiseli zomthwalo wokucheba zihlala zisetyenziselwa izikali zeqonga kunye nokunye. Iseli yomthwalo wengcinezelo idla ngokufakwa phantsi kwesakhiwo (isitya, i-silo, njl.), Ethwala izinto ezinzima ezivela phezulu kwaye ngokuqhelekileyo yenzelwe imithwalo ephezulu. Ngakolunye uhlangothi, kwiseli yomthwalo wokutsalwa, ubunzima buxhunyiwe kwiseli yomthwalo. Iseli yomthwalo yinxalenye ebalulekileyo yesikali seqonga kunye nesikali seqonga.

Ingaba isivamvo sisebenza njani?

Nangona imathiriyeli ye-elastomer izinzile, ikwanayo ne-elasticity encinci. Oku kuthetha ukuba xa ubunzima bubekwe kwisikali, amandla aya kusebenza kumzimba we-elastic. Igama elithi elastomer ekuqaleni livela kwinto yokuba le mathiriyeli ikhubazeke kancinane ngenxa yesi siphumo, kodwa emva kokuba kungekho mandla asetyenziswa kuyo, iya kubuyela kwimo yayo yokuqala, oko kukuthi, "i-elasticity". Oku kukuguqulwa kwe-elastic element yokulinganisa.
