Abstract

Oppfinnelsen vedrører en elektrisk måleanordning for å utføre en elektrisk impedansmåling på en kontaktfri måte. Måleanordningen omfatter en måleanordning som er tilveiebrakt med impedansen (7, 8) som skal måles og en passiv resonanskrets (4) som er tilkoblet dertil for å generere et målesignal som skal mottas trådløst av en separat aktiv sender- og mottakerenhet for å bestemme den elektriske impedansen, ved trådløst mottak av et utspørringssignal overført av den aktive sender- og mottakerenheten. Videre er måleenheten tilveiebrakt med en ytterligere referansekrets (5) som er fortrinnsvis tilkoblet resonanskretsen for å generere et referansesignal som skal mottas av den aktive sender- og mottakerenheten, avhengig av utspørringssignalet.
