1, ho lemoha ho etsoa ka tsela e itseng ea 'mele, ho khetholla palo ea liparamente tse lekantsoeng tse leng tsa mefuta e itseng, e le ho fumana hore na liparamente tse lekantsoeng lia tšoaneleha kapa hore na palo ea liparamente e teng. Ts'ebetso ea ho bapisa bongata bo sa tsejoeng bo lekantsoeng le bongata bo tloaelehileng ba mofuta o tšoanang, ho fumana bongata ba bongata bo tloaelehileng bo lekantsoeng ke sehlopha se lekantsoeng, le ho hlalosa bongata bona ka lipalo.
Lefapheng la boiketsetso le ho lemoha, mosebetsi oa ho lemoha ha se feela ho hlahloba le ho lekanya lihlahisoa tse felileng kapa lihlahisoa tse sa phethoang hantle, empa hape le ho hlahloba, ho laola le ho laola ts'ebetso ea tlhahiso kapa ntho e tsamaeang ho e etsa hore e be boemong bo botle ka ho fetisisa bo khethiloeng ke batho, hoa hlokahala ho lemoha le ho lekanya boholo le phetoho ea liparamente tse fapaneng ka nako efe kapa efe. Theknoloji ena ea ho lemoha le ho lekanya ts'ebetso ea tlhahiso le lintho tse tsamaeang ka nako ea sebele e boetse e bitsoa theknoloji ea tlhahlobo ea boenjiniere.
Ho na le mefuta e 'meli ea ho lekanya: tekanyo e tobileng le tekanyo e sa tobang
Tekanyo e tobileng ke ho lekanya boleng bo lekantsoeng ba ho baloa ha mithara ntle le ho bala, joalo ka: ho sebelisa thermometer ho lekanya mocheso, ho sebelisa multimeter ho lekanya motlakase
Tekanyo e sa tobang ke ho lekanya bongata bo 'maloa ba' mele bo amanang le ho lekanngoa, le ho bala boleng bo lekantsoeng ka kamano ea ts'ebetso. Mohlala, matla a P a amana le motlakase oa V le motlakase oa I, ke hore, P=VI, 'me matla a baloa ka ho lekanya motlakase le motlakase oa hona joale.
Tekanyo e tobileng e bonolo ebile e bonolo, 'me hangata e sebelisoa ts'ebetsong. Leha ho le joalo, maemong ao ho lekanya ka kotloloho ho sa khoneheng, tekanyo e tobileng e sa thabiseng kapa phoso ea tekanyo e tobileng e kholo, tekanyo e sa tobang e ka sebelisoa.
Khopolo ea sensor ea photoelectric le sensor
Mosebetsi oa sensor ke ho fetolela bongata bo seng ba motlakase hore e be tlhahiso ea bongata ba motlakase eo ho nang le kamano e tobileng e tsamaellanang le eona, e leng sebopeho sa sistimi ea bongata bo seng ba motlakase le sistimi ea bongata ba motlakase. Ts'ebetsong ea ho lemoha le ho laola, sensor ke sesebelisoa sa bohlokoa sa phetoho. Ho ea ka pono ea matla, sensor e ka aroloa ka mefuta e 'meli: e 'ngoe ke sensor ea taolo ea matla, e tsejoang hape e le sensor e sebetsang; e 'ngoe ke sensor ea phetoho ea matla, e tsejoang hape e le sensor e sa sebetseng. Sensor ea taolo ea matla e bolela sensor e tla lekanyetsoa phetohong ea liparamente tsa motlakase (joalo ka khanyetso, capacitance) liphetoho, sensor e hloka ho eketsa phepelo e khahlisang ea motlakase, e ka lekanyetsoang liphetoho tsa liparamente ho ba motlakase, liphetoho tsa hona joale. Sensor ea phetoho ea matla e ka fetola ka ho toba phetoho e lekantsoeng hore e be phetoho ea motlakase le hona joale, ntle le mohloli oa kantle oa ho hlasimolla.
Maemong a mangata, bongata bo seng ba motlakase bo lokelang ho lekanyetsoa ha se mofuta oa bongata bo seng ba motlakase boo sensor e ka bo fetolang, e leng se hlokang ho eketsa sesebelisoa kapa sesebelisoa ka pel'a sensor se ka fetolang bongata bo seng ba motlakase bo lekantsoeng ho ba bongata bo seng ba motlakase boo sensor e ka bo amohelang le ho bo fetola. Karolo kapa sesebelisoa se ka fetolang motlakase o seng oa motlakase o lekantsoeng hore e be motlakase o fumanehang ke sensor. Mohlala, ha ho lekanyetsoa motlakase ka gauge ea khatello ea khanyetso, ho hlokahala ho hokela gauge ea khatello ho karolo ea elastic ea khatello e rekisoang, karolo ea elastic e fetola khatello hore e be matla a khatello, 'me gauge ea khatello e fetola matla a khatello hore e be phetoho khanyetsong. Mona gauge ea khatello ke sensor, 'me karolo ea elastic ke sensor. Sensor le sensor ka bobeli li ka fetola motlakase o seng oa motlakase o lekantsoeng ka nako efe kapa efe, empa sensor e fetola motlakase o seng oa motlakase o lekantsoeng hore e be motlakase o fumanehang, 'me sensor e fetola motlakase o seng oa motlakase o lekantsoeng hore e be motlakase.
