I-PT100Ingabe inzwa yokulinganisa yokumelana nomgomo wayo osebenza ngokususelwa oguqukweni kuma-conductor wokumelana namazinga okushisa. I-PT100 yenziwe ngeplatinamu emsulwa futhi inokuqina okuhle kanye nokuqina, ngakho-ke kusetshenziselwa kabanzi ukukala izinga lokushisa. Kwa-Zero Degrees Celsius, inani lokumelana le-PT100 lingama-100 ohms. Njengoba izinga lokushisa lenyuka noma lincipha, ukumelana kwalo kwanda noma kunciphe ngokufanele. Ngokukala inani lokumelana ne-PT100, izinga lokushisa lendawo yalo libalwa ngokunembile.
Lapho inzwa ye-PT100 isendaweni eqhubekayo yamanje, ukuphuma kwayo kwe-voltage kulingana noshintsho lokushisa, ngakho-ke izinga lokushisa lingalinganiswa ngokungaqondile ngokulinganisa amavoluti. Le ndlela yokulinganisa ibizwa ngokuthi "uhlobo lokushisa lwe-voltage lokuphuma" lokushisa lokushisa. Enye indlela evamile yokulinganisa indlela "yohlobo lokuvimbela ukumelana", olubala izinga lokushisa ngokulinganisa inani lokumelana ne-PT100. Akunandaba nendlela esetshenzisiwe, inzwa ye-PT100 ihlinzeka ngezilinganiso ezinembile zokushisa futhi isetshenziswa kabanzi ezinhlobonhlobo zokulawula izinga lokushisa kanye nokuqapha izinhlelo zokusebenza.
Ngokuvamile, inzwa ye-PT100 isebenzisa umgomo wokumelana nomqhubi wokushintshana ngokulinganisa ukukala izinga lokushisa ngokulinganisa ngokulinganisa ngokulinganisa noma ukulinganisa okuphezulu kwemiphumela yokulinganisa kokushisa kokulawulwa kwezinga lokushisa.
