Katangar tsaro ta shigarwar thermocouple na iya ware kuma canza siginar thermocouple (TC) a wurare masu haɗari zuwa siginar lantarki ta 4-20mA, sannan ta fitar da su zuwa yankin aminci. Wannan katangar tsaro tana da diyya ta hanyar haɗin sanyi kuma ana iya tsara ta cikin hikima. Ana iya saita ainihin kewayon thermocouple ta hanyar software na kwamfuta. Yana da ayyukan ƙararrawa ta karyewa ta waya da ƙararrawa daga waje. Wannan samfurin yana buƙatar samar da wutar lantarki mai zaman kanta, tare da samar da wutar lantarki da aka keɓe, shigarwa, da tashoshin fitarwa. "*" yana wakiltar nau'in shigarwar thermocouple, kuma takamaiman samfurin an wakilta shi da lambar (duba "Nau'in Siginar Shigarwa da Tebur Mai Nisa" don cikakkun bayanai).
