Makina otulutsa ma elekitiromatromagnetic (Emfs), amadziwika kuti ali ndi mwayi woyenera kuchita zakumwa zowoneka bwino padziko lonse lapansi ngati mabisiki olamulira.
M'magawo monga chithandizo chamadzi, kukonza kwamankhwala, chakudya & chakumwa, ndi mankhwala opangira, makampani akufunika kwambiriKukula koyenera, kopanda ulemu. Izi zikuyendetsa chikakamizo champhamvu cha okalamba omwe ali ndi zida zapamwamba kwambiri okhala ndi zowunikira zapamwamba, ma protocor a digito, komanso zida zosagonjetseka.
Zochitika posachedwa mu mawonekedwe a sensor zakulitsa kwambiri ntchito za Emfs. Zatsopano, monga ceramic, pla, ndi mphira zolimba - zimathandizira pakuchita opaleshoni zowoneka bwino kwambiri, zankhanza, ndi malo otentha kwambiri. Pakadali pano, kuphatikiza kwaHart, modbus, ndi kulumikizana kopanda zingweakuthandizira kusintha kwa digito mwachangu kwa malo opangira padziko lonse lapansi.
