Magnetic position sensors
(IOP Publishing, 2022)
Magnetic position sensors are popular in industrial and automotive applications since they are robust, resistant to dust and oil, and can be cheap. This was traditionally accompanied by low accuracy. However, new precise ...
Multiwire Parallel Fluxgate Sensors
(IEEE, 2022)
Fluxgate sensors with straight wire or rod cores are used in NDT, portable gradiometers and sensor arrays and for the detection of small objects. We show that their sensitivity at the voltage output mode depends on the ...

(Elsevier, 2022)
Non-planar fluxgate sensors measuring the magnetic fields in the uT range are required for electric current, position, and torque transducers. We report the first sensor based on an inkjet-printed 17 mm diameter ring core. ...
Sensitivity and noise of parallel fluxgate sensor with amorphous wire cores
(Elsevier, 2022)
Fluxgate sensors are vectorial magnetic field sensors suitable for the measurement of fields up to mT with maximum pT resolution. Due to their low weight, low power, and low cost, fluxgates are ideal sensors to monitor the ...
Enhancing Performance of Fluxgate Sensors Using Annealed Nanocrystalline Core
(IEEE, 2023)
The magnetic core is one of the most important parts of a fluxgate sensor. This article presents a study of fluxgate sensors with a core based on nanocrystalline Fe73.5Cu1Nb3Si13.5B9 wire and compares their performance to ...
Rectangular Busbar With Circular Sensing Part for Wideband Current Measurement
(IEEE, 2023)
A simple, reliable, and novel busbar sensing configuration for frequency-independent current measurement is presented in this article. Yokeless current transducers using arrays of magnetic sensors around a rectangular ...
Effect of external DC field on current transformers with amorphous and nanocrystalline cores
(Elsevier, 2022)
Nanocrystalline and amorphous stress-annealed and field annealed tapes are used for cores of DC-tolerant current transformers. We analyze the influence of external DC field of arbitrary direction on the performance of these ...
DC current sensor using switching-mode excited in-situ current transformer
(Elsevier, 2020)
DC current component in the power grid may cause gross measurement errors and lead to overheating of power transformers. We have previously developed method how to measure DC current using fluxgate effect in existing current ...
Rogowski Coil with Ferromagnetic Powder Core
(IEEE, 2022)
We have used nanocrystalline powder to build a core for Rogowski coils suitable for application in energy meters.
The sensor linearity error is 0.32% of full scale (FS) of its 20 A range, which is acceptable for this ...
Modeling of hysteresis loops using rational and power functions
(Elsevier, 2021)
Simple and precise hysteresis models with a small number of parameters allowing fast calculation are required for the magnetic analysis, as the field is calculated in a very large number of points. This paper presents a ...
