Ingcaciso yeMveliso
imitha yokulawula ubushushuluhlobo lwesixhobo esilungiselelwe ngokuthe ngqo ukulawula ubushushu, esisetyenziswa ngokubanzi kwiindawo ezininzi ngenxa yokubeka iliso lobushushu obuchanekileyo kunye namandla olawulo. Umsebenzi wayo ongundoqo kukulinganisa iqondo lobushushu bemeko-bume{1}}ngexesha lokwenyani, kwaye emva koko uhlengahlengise ngokuzenzekelayo isicwangciso-qhinga solawulo olusekwe kwiparamitha zobushushu obusetwe kwangaphambili ukuzinzisa ubushushu bemo engqongileyo okanye izixhobo ngaphakathi koluhlu olufanelekileyo, ukuphepha iingxaki ezibangelwa ngamaqondo obushushu aphezulu okanye aphantsi. Nokuba zizixhobo zasekhaya kubomi bemihla ngemihla, izixhobo zoomatshini kwimveliso yemizi-mveliso, okanye izixhobo zobuchwephesha kwicandelo lezonyango, bonke baxhomekeke kwinkxaso yabalawuli bobushushu - abanako ukukhusela kuphela izixhobo ekonakalisweni kobushushu obugqithisileyo, kodwa baphinde baphucule ukusebenza kakuhle kwezixhobo, ngelixa bedala indawo yokuhlala etofotofo, yokusebenza, okanye yonyango yabantu. Indima yabo ibalulekile.
Ukusuka kwimbono yemigaqo esisiseko yokusebenza, ukusebenza kwemitha yokulawula ubushushu kuxhomekeke kakhulu ekuhambeni okunengqiqo "kokubeka iliso lobushushu, ukusetyenzwa komqondiso, ukulawulwa kokulawula", apho inzwa yokushisa iyona nxalenye ephambili yokulinganisa ubushushu, kwaye isixhobo sokulawula sinoxanduva lokugqiba ummiselo wokushisa. Izinzwa zobushushu ezisetyenziswayo ngoku zibandakanya i-thermocouples, i-thermistors, kunye ne-semiconductor sensors zobushushu, ezifumana ukubonwa kobushushu ngeempawu ezahlukeneyo zomzimba.
Ngokukodwa, i-thermocouple yenziwe ngeengcingo ezimbini ezenziwe ngezinto ezahlukeneyo. Xa iziphelo ezimbini zeengcingo zikwiindawo ezahlukeneyo zobushushu, umahluko onokuthi uveliswe ngenxa yesiphumo se-thermoelectric. Umlawuli weqondo lokushisa unako ukubala ubushushu obuhambelanayo be-ambient ngokulinganisa ixabiso lalo mahluko onokwenzeka; I-Thermitors yongeza izinto ezinobushushu bobushushu kumacandelo azo okumelana, kwaye amaxabiso abo okumelana nokutshintsha kobushushu. Ngokulinganisa ukuguquguquka kwamaxabiso oxhathiso, ubushushu bexesha lokwenyani{3} bunokufunyanwa umva; Izinzwa zeqondo lokushisa le-semiconductor zisebenzisa iimpawu zokumelana nezixhobo ze-semiconductor ukutshintsha kunye neqondo lokushisa, kwaye zibale ubushushu bangoku ngokubeka iliso utshintsho kwixabiso labo lokumelana. Emva kokuba i-sensor ifumene idatha yeqondo lokushisa, umlawuli weqondo lokushisa uya kuthelekisa iqondo lokushisa langempela kunye neqondo lokushisa elimiselweyo, kwaye afezekise ulawulo oluchanekileyo lweqondo lokushisa ngokulungelelanisa isimo sokutshintsha isixhobo sokulawula (njengokuqala okanye ukucima ukufudumala kunye nokupholisa amacandelo).
Iifayile ezishisayo: imitha yokulawula ubushushu, ababoneleli bemitha yokulawula ubushushu baseTshayina
