Inzwa yokucindezela inzwa esetshenziselwa ukukala ingcindezi ngokuyiguqula ibe isignali kagesi. Isimiso sayo sokusebenza sisekelwe ngokuyinhloko ekucindezelweni kwe-deformation yesakhiwo sangaphakathi senzwa, okubangela izinguquko kumjikelezo wangaphakathi. Isimiso sokusebenza senzwa yokucindezela sichazwe ngokuningiliziwe ngezansi.

Isakhiwo esiyisisekelo senzwa yokucindezela sihlanganisa isici sokungeniswa, isifunda sokucubungula isignali kanye nezindlu. Inzwa iyingxenye ewumgogodla yenzwa yokucindezela, evamise ukwenziwa ngezinto ezinwebekayo, njenge-silicon, i-quartz, insimbi, njll. Uma kusetshenziswa ingcindezi yangaphandle, into yokungeniswa izokonakala, futhi izinga lokuguquguquka lilingana ubukhulu bokucindezela.

Ukuguqulwa kwe-induction element kuzodala ukuguqulwa kwemingcele kagesi njengokumelana, amandla kanye ne-inductance. Izinguquko kule mingcele zingalinganiswa futhi ziguqulwe ngamasekhethi okucubungula isignali, okuholela esignali kagesi elingana nosayizi wokucindezela. Isifunda sokucubungula isignali ngokuvamile siqukethe ama-amplifiers, izihlungi, iziguquli ze-analog-to-digital, njll. Iqhaza lazo eliyinhloko ukukhulisa, ukuhlunga kanye nokwenza idijithi okukhishwayo kwesignali ebuthaka ngento yokungeniswa, ukuze kube lula ukucutshungulwa kwedatha nokuhlaziywa okulandelayo.

Igobolondo lenzwa yokucindezela ngokuvamile lenziwe ngensimbi engagqwali, i-aluminium alloy nezinye izinto, futhi indima yalo eyinhloko ukuvikela izingxenye zokungeniswa kanye nama-circuits okucubungula isignali ekuphazamiseni nasekulimaleni okuvela endaweni yangaphandle. Igobolondo ngokuvamile alinamanzi, lingangenwa uthuli, lingagqwali kanye nezinye izici ukuze lizivumelanise nezimo ezihlukahlukene zokusebenza.

Ngamafuphi, isimiso sokusebenza senzwa yokucindezela sisekelwe ekuguqulweni kwesici sokungeniswa ekucindezelweni, okubangela ushintsho kumjikelezo wangaphakathi, futhi ukukhishwa kokugcina kwesignali kagesi ngokulingana nobukhulu bokucindezela. Inzwa yokucindezela isetshenziswa kabanzi ku-automation yezimboni, imboni yezimoto, imishini yezokwelapha neminye imikhakha, iyithuluzi elibalulekile ekukhiqizweni kwezimboni zesimanje.
