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 ...
Electroplated FeNi ring cores for fluxgates with field induced radial anisotropy
(American Institute of Physics, 2015)
Being able to control the anisotropy of a magnetic core plays an important role in the development of a fluxgate sensor. Our aim is to induce anisotropy orthogonal to the direction of excitation because it generates a ...
Precise Scalar Calibration of a Tri-Axial Braunbek Coil System
(IEEE, 2015)
A calibration of the well-defined Braunbek coil system was carried out using the scalar method. The whole measuring setup was designed to minimize the uncertainty of the scalar calibration procedure. The measurement time ...
A Novel Eddy Current Speed Sensor with Ferrite E-Core
(IEEE, 2020)
This letter presents a novel speed sensor based on motion-induced eddy currents in conductive moving parts. The magnetic yoke is an E-shaped ferrite core. The excitation coil is on the center leg of the E-core, and two ...
Precise Magnetic Sensors for Navigation and Prospection
(Springer-VDI-Verlag GmbH & Co. KG, 2015)
Navigation, position tracking, search for unexploded ammunition, and geophysical prospection of magnetic or conducting ore are key applications where very small magnetic field signatures and field increments should be ...
Three-Phase Busbar Current Transducer
(IEEE, 2019)
A true three-phase 1000 A busbar current transducer is based on six micro-fluxgate sensors. Instead of using
three independent single-phase current transducers, we use the full information from each sensor. Two TI DRV425 ...
Noise dependence on temperature in fluxgates with electroplated core
(Elsevier Science, 2016)
Samples of electrodeposited fluxgate sensors with varying magnetostriction coefficient were manufactured and their noise was studied at various temperatures. We show that the noise of the fluxgate is, under some conditions, ...
Temperature Influence on Position Transducer for Pneumatic Cylinder
(IEEE SENSORS, 2018)
In this paper, temperature sensitivity of inductance position transducer of a pneumatic cylinder system is presented. The magnetic solid iron rod and aluminum piston position changes the inductance of the tubular coil ...
Analysis of Material Effect on Rail Impedance
(IEEE, 2018)
In this paper, two different solid iron materials are used for two different size rails. The internal impedances, resistances and inductances of the rails are evaluated and analyzed with time harmonic and time stepping ...
