Effects of Core Dimensions and Manufacturing Procedure on Fluxgate Noise 

Janošek M.; Vyhnánek J.; Zikmund A.; Butvin P.; Butvinová B. (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 

Butvin P.B.; Janošek M.; Ripka P.; Butvinová B.B.; Švec sr. P.Š.; Kuzminski M.K.; Švec Jr. P.Š.; Janičkovič D.J.; Vlasák G.V. (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 

Ripka P.; Přibil M.; Butta M. (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 

Butta M.; Janošek M.; Ripka P.; Kraus L.; El Kammouni R. (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 

Butta M.; Ripka P.; Janošek M.; Přibil M. (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 ...

Effect of Electroplated Ni1-xFex Composition on the Field-Induced Anisotropy 

Butta M.; Ripka P. (IEEE, 2016)
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 ...

Hluk kompresoru tepelného čerpadla vzduch-voda 

Kučera M.; Králíček J.; Langerová E. (Společnost pro techniku prostředí, 2021)
Článek se zaměřuje na hluk a vibrace šířené od nejčastěji instalovaného typu tepelných čerpadel vzduch- -voda do okolí a do stavebních konstrukcí. Z funkčního hlediska je téma omezeno na tepelná čerpadla s elektricky ...

Effect of Stress Induced Anisotropy on the Noise of Ring-core Fluxgate 

Butta M.; Ripka P.; Kraus L. (IEEE, 2015)
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 ...

Korekce výpočtových metodik emisí hluku na rekonstruovaných železničních tratích v České republice jako nástroj k objektivizaci modelovaných hodnot 

Týfa L.; Javořík T.; Vašica D.; Ládyš L.; Biľová M.; Matoušek A. (TUKE, Strojnícka fakulta, Katedra environmentalistiky, 2014)
Již několik let dochází v České republice k rekonstrukcím železničních tratí. Avšak doposud nebylo ověřeno, jakým způsobem ovlivní změny železničního svršku emise hluku ze železniční dopravy. To má za následek, že v případě ...
