Don yanayin da ake buƙatar aunawa, galibi ana samun na'urori masu auna firikwensin da yawa waɗanda zasu iya auna ta.
Alal misali, na'urori masu auna zafin jiki sun haɗa da: thermocouples, thermal resistors, thermistors, semiconductor PN junctions, IC zafin jiki na'urori masu auna firikwensin, fiber optic zafin jiki na'urori masu auna sigina, da dai sauransu A karkashin yanayi cewa duk iya saduwa da ma'auni kewayon, daidaito, gudun, da kuma yanayin amfani, ya kamata mu mayar da hankali kan dalilai kamar low cost, ko da matching kewaye ne mai sauki, da kuma dogara ga zabin firikwensin.
1. Babban firikwensin fitarwa na sigina:
