Imitha yokulawula izinga lokushisa

Imitha yokulawula izinga lokushisaiwuhlobo lwethuluzi eliklanyelwe ngokukhethekile ukulawula izinga lokushisa, elisetshenziswa kakhulu emikhakheni eminingi ngenxa yamakhono alo anembile okuqapha izinga lokushisa kanye namandla okulawula. Umsebenzi wayo oyinhloko ukukala izinga lokushisa lendawo ngesikhathi sangempela-, bese ulungisa ngokuzenzakalelayo isu lokulawula ngokusekelwe kumingcele yezinga lokushisa elisethiwe kusengaphambili ukuze kunziswe izinga lokushisa lendawo noma okokusebenza phakathi kwebanga elifanele, ukugwema izinkinga ezibangelwa izinga lokushisa eliphezulu noma eliphansi. Kungakhathaliseki ukuthi izinto zikagesi zasendlini ekuphileni kwansuku zonke, okomshini ekukhiqizweni kwemboni, noma amathuluzi ochwepheshe emkhakheni wezokwelapha, zonke zithembele ekusekelweni izilawuli zezinga lokushisa - azikwazi ukuvikela kuphela okokusebenza emonakalweni wamazinga okushisa aphakeme, kodwa futhi zithuthukise ukusebenza kahle kwesisetshenziswa, kuyilapho kwakheka indawo yokuhlala enethezekile, yokusebenza, noma yokwelapha yabantu. Indima yabo ibalulekile.

Ngokombono wezimiso zokusebenza eziyisisekelo, ukusebenza kwemitha yokulawula izinga lokushisa ikakhulukazi kuncike ekuhambeni okunengqondo "kokuqapha izinga lokushisa, ukucubungula isignali, ukukhishwa kokulawula", lapho inzwa yokushisa iyingxenye eyinhloko yokulinganisa izinga lokushisa, futhi idivayisi yokulawula inesibopho sokuqedela ukulawulwa kwezinga lokushisa. Izinzwa zokushisa ezivame ukusetshenziswa okwamanje zifaka ama-thermocouples, ama-thermistors, nezinzwa zokushisa ze-semiconductor, ezithola ukutholwa kwezinga lokushisa ngezici zomzimba ezihlukile.

Ngokuqondile, i-thermocouple yakhiwa izintambo ezimbili ezenziwe ngezinto ezahlukene. Uma iziphetho ezimbili zezintambo zisezindaweni zokushisa ezihlukene, umehluko ongaba khona ukhiqizwa ngenxa yomphumela we-thermoelectric. Isilawuli sezinga lokushisa singabala izinga lokushisa elihambisanayo le-ambient ngokukala inani lalo mehluko ongaba khona; Ama-thermistors engeza izinto ezizwelayo ekushiseni ezingxenyeni zazo zokumelana, futhi amanani awo okumelana ashintsha ngokushintsha kwezinga lokushisa. Ngokulinganisa ukuguquguquka kwamanani okumelana,{3}}isikhathi sangempela sokushisa singalinganiswa ngokuhlehla; Izinzwa zokushisa kwe-semiconductor zisebenzisa izici zokumelana nezinto ezisetshenziswayo ukuze zishintshe nezinga lokushisa, futhi zibale izinga lokushisa lamanje ngokuqapha izinguquko kumanani azo wokumelana. Ngemva kokuba inzwa ithole idatha yezinga lokushisa, isilawuli sezinga lokushisa sizoqhathanisa izinga lokushisa langempela nezinga lokushisa elimisiwe, futhi sizuze ukulawulwa kwezinga lokushisa okunembile ngokulungisa isimo sokushintshwa kwedivayisi yokulawula (njengokuqalisa noma ukuvala izingxenye zokushisisa nokupholisa).

Amashadi ashisayo: imitha yokulawula izinga lokushisa, abahlinzeki bamamitha okulawula izinga lokushisa e-China
