Shingayen keɓantawar thermistor na iya juyar da siginonin Pt100 na waya biyu da na'urorin wutar lantarki uku (RTDs) a wurare masu haɗari zuwa siginar 1:1 na thermistor kuma aika shi zuwa yankin aminci. Ana iya daidaita shi da hankali, kuma ana iya saita ainihin kewayon juriyar zafi ta hanyar software na kwamfuta. Yana da ayyukan ƙararrawar fasa waya da ƙararrawa mara iyaka.
Wannan samfurin yana buƙatar samar da wutar lantarki mai zaman kanta, tare da keɓewar samar da wutar lantarki, shigarwa, da tashoshi masu fitarwa.
