Effect of Electroplated Ni1-xFex Composition on the Field-Induced Anisotropy
Field-induced anisotropy has been proposed as an effective method to produce ferromagnetic rings with radial anisotropy for fluxgate cores. Compared with stress-induced anisotropy, this method easily allows generating a ...
Flugate Sensor With Pulse Feedback
Fluxgate sensors have typically only 100 μT range, which sometimes limits their applications. The main obstacle for increasing the measurement range is the power dissipated in their feedback coil. Until now, the feedback ...
Effects of Core Dimensions and Manufacturing Procedure on Fluxgate Noise
(Polish Academy of Sciences, 2014)
The effect of demagnetizing factor and manufacturing procedure on noise of the fluxgate probes, manufactured from metallic glasses, is presented. The fluxgate probes were either tape-wound, or flat, wet-etched ringcore ...
A Fluxgate Current Sensor With an Amphitheater Busbar
Large dc and ac electric currents are often measured by open-loop sensors without a magnetic yoke. A widely used configuration uses a differential magnetic sensor inserted into a hole in a flat busbar. The use of a ...
AC/DC Current Transformer With Single Winding
AC/DC Current Transformer With Single Winding is a device which allows simultaneously measure AC and DC current using fluxgate effect
Effect of Stress Induced Anisotropy on the Noise of Ring-core Fluxgate
In this paper we show how an anisotropy perpendicular to the direction of excitation is favourable to obtain low noise in fluxgate sensors. We produced ring cores by electroplating NiFe thin film (6 μm) over a bended copper ...
Fluxgate Offset Study
Offset and its long-term stability is a weak point of fluxgate sensors. Even the ultrastable sensors kept at no vibrations and stable temperature at magnetic observatories show offset drift. Such drift of the fluxgate ...
Influence of Magnetostriction of NiFe Electroplated Film on the Noise of Fluxgate
We electroplated NiFe thin-film over a copper layer using different current density. Magnetostriction is changed from negative to positive values, with minimum magnetostriction found at around Fe19Ni81 composition. When ...
Multiwire Core Fluxgate
(Elsevier Science, 2009)
Multiwire core fluxgate has higher sensitivity due to the higher cross=sectional area of the core
Magnetostriction Offset of Fluxgate Sensors
Magnetostriction Offset of Fluxgate Sensors: we examined the origoins of offset both theoretically an experimentally
