Ikigereranyo cy'ubushyuhe bwo kurwanya (RTDs), kizwi kandi nka resistance ya termometero, kumva neza ubushyuhe bwimikorere hamwe nurwego rwiza rwo gusubiramo no guhinduranya ibintu.Muguhitamo ibintu bikwiye hamwe no gukingira, RTDs irashobora gukora mubushyuhe bwa (-200 kugeza 600) ° C [-328 kugeza 1112] ° F.
