Katangar tsaro ta shigarwar RTD za ta iya canza siginar waya biyu ko uku ta thermistor (RTD) a wurare masu haɗari zuwa siginar wutar lantarki ta 4-20mA sannan ta fitar da su zuwa yankin aminci. Ana iya tsara shi cikin hikima, kuma ana iya saita ainihin kewayon juriyar zafi ta hanyar software na kwamfuta. Yana da ayyukan ƙararrawa ta karyewar waya da ƙararrawa daga waje.
Wannan samfurin yana buƙatar samar da wutar lantarki mai zaman kanta, tare da samar da wutar lantarki mai zaman kanta, shigarwa, da tashoshin fitarwa.
