Idatha ye-PT100iyinzwa yokushisa yokumelana nesimiso sayo sokusebenza sisekelwe ekushintsheni kokumelana nomqhubi ngezinga lokushisa. I-PT100 yenziwe ngeplatinamu emsulwa futhi inozinzo oluhle kanye nomugqa, ngakho isetshenziswa kabanzi ukukala izinga lokushisa. Ku-zero degrees Celsius, inani lokumelana le-PT100 liyi-100 ohms. Njengoba izinga lokushisa likhuphuka noma lehla, ukumelana kwalo kuyanda noma kuncipha ngokufanele. Ngokulinganisa inani lokumelana le-PT100, izinga lokushisa lendawo yalo lingabalwa ngokunembile.
Lapho inzwa ye-PT100 isekugelezeni kwamanje njalo, ukuphuma kwayo kwamandla kagesi kuhambisana nokushintsha kwezinga lokushisa, ngakho izinga lokushisa lingalinganiswa ngokungaqondile ngokulinganisa i-voltage. Le ndlela yokulinganisa ibizwa nge-"voltage output type" isilinganiso sezinga lokushisa. Enye indlela yokulinganisa evamile "uhlobo lokuphuma kokumelana", olubala izinga lokushisa ngokulinganisa inani lokumelana le-PT100. Kungakhathaliseki ukuthi iyiphi indlela esetshenzisiwe, inzwa ye-PT100 inikeza izilinganiso zokushisa ezinembile kakhulu futhi isetshenziswa kabanzi ezinhlobonhlobo zokulawula izinga lokushisa kanye nezinhlelo zokusebenza zokuqapha.
Ngokuvamile, inzwa ye-PT100 isebenzisa isimiso sokumelana nomqhubi oshintshayo ngokushisa ukuze kulinganiswe ngokunembile izinga lokushisa ngokulinganisa ukumelana noma i-voltage, inikeze imiphumela yokulinganisa izinga lokushisa enembayo ephezulu yokulawula ukushisa okuhlukahlukene kanye nezinhlelo zokusebenza zokuqapha.
