Current Sensor in PCB Technology
(IEEE, 2005-06)
A novel DC/AC current sensor works on the fluxgate principle. The core in the form of a 7/10-mm ring made of electrodeposited permalloy is sandwiched in the middle of a printed circuit board (PCB), whereas the sensor ...
Pulse Excitation of Micro-Fluxgate Sensors
(IEEE, 2001-07)
Miniature fluxgate sensors with symmetrical closed core elements on both sides of the planar coils were manufactured using standard microtechnology. The new sensors have shown substantial improvement over the standard ...
Linearity of Pulse Excited Coil-Less Fluxgate
(IEEE, 2009-10)
In this paper, we study the open-loop linearity of pulse excited coil-less fluxgate. Narrow current pulses can be used instead of classical sinewave for the excitation of the coil-less fluxgate. This method has shown several ...
Double Coil-Less Fluxgate in Bridge Configuration
(IEEE, 2010-02)
In this paper, a new method for excitation of coil-less fluxgate is presented. The purpose of this method is to reduce the spurious component of the output voltage, allowing us to increase the amplification. The method is ...
Magnetic Microwires With Field-Induced Helical Anisotropy for Coil-Less Fluxgate
(IEEE, 2010-07)
We present a new method for production of magnetic microwire with helical anisotropy. Coil-less fluxgate sensors are generally composed of a bimetallic wire excited by an alternating current; in order for the wire to work ...
A 3-Phase Current Transducer based on microfluxgate sensors
(Elsevier, 2019)
Novel 3-phase DC/AC current transducer for 3-phase current lines is based on 8 integrated fluxgate sensors. Using full information from each sensor rather than gradiometric pairs, we suppress crosstalk between individual ...
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 ...
Field Annealed Closed-path Fluxgate Sensors Made of Metallic-glass Ribbons
(Elsevier Science, 2012)
One-step field annealing of Co-based metallic glass was chosen to acquire low-magnetostrictive material with anisotropy required to reduce noise by favoring magnetization rotation. Despite the risk of bending stress ...
Fluxgate Offset Study
(IEEE, 2014)
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
(IEEE, 2014)
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 ...
