In this paper the application possibilities of fluxset type magnetic field sensor are discussed. Simple driving and measuring circuits developed for this type of magnetic detector is described. The operational principles of the fluxset sensor is discussed highlighting its capabilities for the measurement of AC and time-dependent magnetic fields. At the end of the paper, experimental results related to eddy current testing (ECT) measurement is presented.
