Mosebetsi oa kutlo ke ho fetolela bongata bo sa sebeliseng motlakase ho tsoa ho bongata ba motlakase moo ho nang le kamano e tobileng e lumellanang le eona, eo ha e le hantle e leng sehokelo pakeng tsa sistimi e seng ea motlakase le sistimi ea bongata ba motlakase.Ts'ebetsong ea ho lemoha le ho laola, sensor ke sesebelisoa sa bohlokoa sa ho fetola.Ho latela pono ea matla, sensor e ka aroloa ka mefuta e 'meli: e' ngoe ke sensor ea matla, e tsejoang hape e le sensor e sebetsang;E 'ngoe ke sensor ea ho fetola matla, e tsejoang hape ka hore ke passive sensor.Sensor ea taolo ea matla e bua ka sensor e tla lekanyetsoa ho fetoha ha mekhahlelo ea motlakase (joalo ka ho hanyetsa, matla) liphetoho, sensor e hloka ho eketsa phepelo ea motlakase e khahlisang, e ka lekanyetsoa li-parameter li fetoha voltage, liphetoho tsa hajoale.Sensor ea phetoho ea matla e ka fetolela phetoho e lekantsoeng ka kotloloho ho phetoho ea motlakase le ea hona joale, ntle le mohloli oa kantle oa ho hlasimolla.
Maemong a mangata, palo eo e seng ea motlakase e lokelang ho lekanyetsoa ha se mofuta oa mefuta e seng ea motlakase eo sensor e ka e fetolang, e hlokang ho eketsa sesebelisoa kapa sesebelisoa ka pel'a sensor e ka fetolang palo e seng ea motlakase e lekantsoeng ho palo e seng ea motlakase eo sensor e ka e amohelang le ho e fetola.Karolo kapa sesebelisoa se ka fetolang motlakase o sa lekantsoeng hore e be motlakase o teng ke sensor.Mohlala, ha u lekanya voltage ka sekhahla sa khatello ea khatello, hoa hlokahala ho hokela sekhahla sa khatello ho karolo ea elastic ea khatello e rekisoang, ntho ea elastic e fetola khatello hore e be matla a khatello, 'me sekhahla sa khatello se fetola matla a khatello hore e be matla a khatello. phetoho ea ho hanyetsa.Mona sekala sa khatello ke kutlo, 'me karolo ea elastic ke sensor.Ka bobeli sensor le sensor li ka fetola motlakase o lekantsoeng ka nako leha e le efe, empa sensor e fetola motlakase o lekantsoeng hore o se ke oa e-ba motlakase, 'me mochine o fetola motlakase o lekantsoeng o se nang motlakase.
