The paper deals with the construction and calibration concept of a modified single sheet tester systems, suitable to perform low-frequency magnetic measurements in engineering laboratories. Firstly, the authors present the configuration of the proposed tester, which can be easily adapted to lamination sheet samples having various sizes. Then, the calibration procedure of the system, based on measurement and numerical simulation results, is reported in detail. Finally, the proposed system has been used to characterize several magnetic lamination strips, comparing the results with the data provided by the manufacturers. The good agreements found in the results comparison, together with the significant cost reduction of the measurements (both in term of execution time, and tester production costs), make appealing the use of the proposed system for engineering measurements on magnetic lamination samples, also having non-standard dimensions.Index Terms -Magnetic materials, electromagnetic measurements, Single Sheet Testes (SST), lamination sheets, electromagnetic modeling, magnetic material testing, non destructive testing, Finite Element Method (FEM).

“…It measures active power in the order of various tenths of milliwatts requiring additional circuitry to satisfy the flipping coil requirements. The features of MR-based watt converters have been analyzed using non-Wheatstone type MR topologies [ 24 , 25 ], or based on the bridge topology but at the level of integrated circuit monitoring, although not for industrial applications [ 26 ]. Considering previous current measurement techniques, resistive current shunts have ohmic losses that generate heat and do not provide electrical isolation.…”

In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with resistive load and less than 1% with capacitive load was obtained. The described application is an example of how TMR sensing technology can play a relevant role in the management and control of electrical energy.
