Ipulaki yokuzwa uwoyela ibhekisela ku-sensor yokucindezela uwoyela. Isimiso siwukuthi uma injini isebenza, idivayisi yokulinganisa ingcindezi ithola ingcindezi kawoyela, iguqule isignali yokucindezela ibe isignali kagesi, bese iyithumela kusekethe yokucubungula isignali. Ngemva kokukhulisa amandla kagesi kanye nokukhulisa amandla kagesi, isignali yokucindezela ekhulisiwe ixhunywe ne-gauge yokucindezela uwoyela ngomugqa wesignali.
Umfutho kawoyela wenjini uboniswa yisilinganiso samandla kagesi phakathi kwamakhoyili amabili kusibonakaliso somfutho kawoyela oguquguqukayo. Ngemva kokwandiswa kwamandla kagesi kanye nokwandiswa kwamandla kagesi, isignali yomfutho iqhathaniswa ne-voltage ye-alamu esethwe kusekethe ye-alamu. Uma i-voltage ye-alamu iphansi kune-voltage ye-alamu, isekethe ye-alamu ikhipha isignali ye-alamu bese ikhanyisa isibani se-alamu ngomugqa we-alamu.
Inzwa yokucindezela uwoyela iyithuluzi elibalulekile lokubona ukucindezela uwoyela kwenjini yemoto. Ukulinganisa kusiza ukulawula ukusebenza okuvamile kwenjini.
Ipulaki yokuzwa uwoyela yakhiwe yi-chip yenzwa yokucindezela ifilimu ejiyile, isekethe yokucubungula isignali, i-housing, idivayisi yebhodi yesekethe egxilile kanye nama-lead amabili (umugqa wesignali kanye nomugqa we-alamu). Isekethe yokucubungula isignali iqukethe isekethe yokunikeza ugesi, isekethe yokunciphisa inzwa, isekethe ye-zerosetting, isekethe yokukhulisa i-voltage, isekethe yokukhulisa ugesi, isekethe yokuhlunga kanye nesekethe ye-alamu.
