Mabapi le li-Sensors tsa Lehlaka
Li-sensor tsa lehlaka li sebelisa makenete kapa electromagnet ho theha matla a khoheli a bulang kapa a koalang switch ea lehlaka ka har'a sensor. Sesebelisoa sena se bonolo se thetsang se laola ka botšepehi lipotoloho tsa thepa e mengata ea indasteri le ea khoebo.

Sehloohong sena, re tla tšohla hore na li-sensor tsa lehlaka li sebetsa joang, mefuta e fapaneng e fumanehang, phapang lipakeng tsa li-sensor tsa Hall Effect le li-sensor tsa lehlaka, le melemo ea bohlokoa ea li-sensor tsa lehlaka. Hape re tla fana ka kakaretso ea liindasteri tse sebelisang li-sensor tsa lehlaka le hore na MagneLink e ka u thusa joang ho theha li-switches tsa lehlaka bakeng sa projeke ea hau e latelang ea tlhahiso.

Li-sensors tsa Reed li sebetsa joang?
Sesebelisoa sa lehlaka ke li-contact tsa motlakase tse etsang potoloho e koetsoeng ha li ama le potoloho e bulehileng ha e arohane. Li-switches tsa lehlaka li theha motheo oa sensor ea lehlaka. Li-sensor tsa lehlaka li na le switch le makenete e matlafatsang ho bula le ho koala ha mabitso. Sistimi ena e ka har'a setshelo se tiisitsoeng ka hermetically.

Ho na le mefuta e meraro ea li-sensor tsa lehlaka: ka tloaelo li-sensor tsa lehlaka tse bulehileng, hangata li-sensor tsa lehlaka tse koetsoeng, le li-sensor tsa lehlaka. Mefuta ena e meraro e ka sebelisa makenete ea setso kapa electromagnet, 'me e' ngoe le e 'ngoe e itšetlehile ka mekhoa e fapaneng hanyane ea ts'ebetso.

Ka tloaelo Open Reed Sensors
Joalo ka ha lebitso le bolela, li-sensor tsena tsa lehlaka li maemong a bulehileng (a khaotsoe) ka boiketsetso. Ha makenete ka har'a sensor e fihla sesebelisoa sa lehlaka, e fetola e 'ngoe le e' ngoe ea likhokahano hore e be lipalo tse fapaneng. Khoheli eo e ncha pakeng tsa likhokahano tse peli e ba qobella ho koala potoloho. Lisebelisoa tse nang le lisensara tsa lehlaka tse bulehileng li qeta boholo ba nako li tima ntle le haeba makenete e sebetsa ka boomo.

Hangata li-Sensors tsa Reed tse koetsoeng
Ka lehlakoreng le leng, li-sensor tsa lehlaka tse koetsoeng hangata li theha li-circuits tse koetsoeng e le boemo ba tsona ba kamehla. Ha se ho fihlela makenete e etsa hore ho be le khoheli e itseng moo switch ea lehlaka e khaohang ebe e senya khokahano ea potoloho. Motlakase o phalla ka har'a sensor e tloaelehileng ea lehlaka ho fihlela makenete e qobella likhokahano tse peli tsa lehlaka ho arolelana polarity e tšoanang ea makenete, e qobellang likarolo tse peli ho arohana.

Latching Reed sensors
Mofuta ona oa sensor ea lehlaka o kenyelletsa ts'ebetso ea li-sensor tsa lehlaka tse koetsoeng le tse tloaelehileng tse bulehileng. Sebakeng sa ho ikamahanya le maemo a nang le matla kapa a se nang matla, li-sensor tsa lehlaka tse latching li lula li le maemong a tsona a ho qetela ho fihlela phetoho e qobelloa ho eona. Haeba electromagnet e qobella switjha hore e be sebakeng se bulehileng, sesebelisoa se tla lula se butsoe ho fihlela makenete ea motlakase e phahama 'me e etsa hore potoloho e koalehe, le ka tsela e fapaneng. Lintlha tsa ts'ebetso le ho lokolla ha switjha li theha hysteresis ea tlhaho, e koalang lehlaka sebakeng.
