1, ho latela tlhahiso eo ke hore, lintlha tse fapaneng tsa ntho e lekantsoeng:

Haeba bongata ba ho kenya

Mokhoa ona oa khethollo o hlalosa ka ho hlaka tšebeliso ea li-sensors, 'me o fana ka mohlala oa basebelisi. Ho bonolo ho khetha li-sensor tse hlokahalang ho latela lintho tse lekantsoeng. Bothata ke hore mekhoa ena ea khethollo e qaqisa linsors ka melao e 'ngoe,' me ho thata ho tsebahatsa tumellano le phapang ea sensor e 'ngoe le e' ngoe ea maikutlo. Ka hona, ho sa tsotelloe ho sa thabise ho tseba melao-motheo ea bohlokoa le ho sekaseka mekhoa ea sensor. Hobane mofuta o ts'oanang oa motho ea sa utloahaleng, e joalo ka Pinohoectric, e ka sebelisoa ho lekanya ho potlakisoa, velocity le boholo le tsona li ka lekanya tšusumetso le matla lia tšoana.

Mokhoa ona oa khethollo o arola mefuta e mengata ea bongata ba 'mele ka mekhahlelo e' meli: palo ea mantlha le bongata bo sa tsoa etsoa. Mohlala, matla a ka nkuoa e le bongata ba 'mele oa mantlha, ao ho ka a fumanang khatello ea' mele, boima, khatello ea maikutlo le toropo li ka nkuoa. Ha re hloka ho lekanya boholo ba 'mele bo kaholimo, re hloka feela ho sebelisa li-sensors tsa matla. Ka hona, ho utloisisa kamano lipakeng tsa 'mele ea mantlha' me ho na le lisebelisoa tse ngata tse nkileng 'mele ho thusa ho sitisa tsamaiso ho sebelisa li-sensors.

2, ho latela molao-motheo oa mosebetsi (ho lemoha) ho khethoa

Molao-motheo oa ho lemoha o bua ka litlamorao tsa 'mele, phello ea lik'hemik'hale ho tsona sensor se sebetsa. Ho na le khanyetso, 'mele, boemo ba boithati, piezoelectric, matla a motlakase, matla a mahlahahlaha, a rachina mahlaseli a nyutlelie, a se ke a ba le sensor.

Mohlala, ho latela molao-motheo oa ha re hanyetsoa ke fapaneng, ho na le li-detertiesters, ho na le li-thirses tsa khatello, li-sensors tsa piezoreita. For example, according to the principle of electromagnetic induction, there are inductive sensors, differential pressure transmitters, eddy current sensors, electromagnetic sensors, magnetoresistive sensors and so on. Ho latela thuto ea semicondtor, ba sa tsotelle

Monyetla oa mokhoa ona oa khalemelo ke hore ho loketse litsebi tsa kutloelo-bohloko ho etsa tlhahlobo ea maikutlo le lipatlisiso tse fapaneng, kahoo hangata li sebelisoa. Bothata ke hore basebelisi ba tla ikutloa ba sa tsitsitse ha ba khetha bansor.

Ka linako tse ling, hangata e bitsoa ka ho kopanya tšebeliso le molao-motheo tse kang ho se sebetse hantle ka tsela ea ho tšoasa motho ea tsoang moeeng, ho qoba mabitso a mangata a sa tsotelleng.
