Crossfield Sensitivity in AMR Sensors
(IEEE, 2009-10)
We discuss the origin of the crossfield sensitivity of AMR sensors, the way how this error may influence the performance of an AMR compass and methods for its correction. Finally, we confirm the simple formulas experimentally. ...
Two-Domain Model for Orthogonal Fluxgate
(IEEE, 2008-11)
In this paper a new model for orthogonal fluxgate is presented. A first attempt to explain the working principle of the orthogonal fluxgates was done in the 1970's. We show that this model does not work well on recently ...
Double-Core GMI Current Sensor
(IEEE, 2005-10)
A novel design of the giant magnetoimpedance contactless current sensor is presented. A double-core structure is used in order to improve the temperature stability. The temperature coefficient of sensitivity and offset ...
Sensitivity and Noise of Wire-Core Transverse Fluxgate
(IEEE, 2010-02)
Fluxgate sensors with cores made of amorphous microwire have low sensitivity due to the small cross-sectional area of the wire. Previous studies with multiwire cores have shown nonlinear increase of sensitivity with number ...
Advances in Magnetic Field Sensors
(IEEE, 2010-06)
The most important milestone in the field of magnetic sensors was when AMR sensors started to replace Hall sensors in many applications where the greater sensitivity of AMRs was an advantage. GMR and SDT sensors finally ...
Off-Center Error Correction of AMR Yokeless Current Transducer
(Hindawi Publishing Corporation, 2017)
We present a method of calibration and error correction of the AMR yokeless current transducer consisting of a circular array of eight anisotropic magnetoresistors (AMR) with one feedback compensation loop. The main sources ...
The effect of conductor permeability on electric current transducers
(American Institute of Physics, 2018)
In this paper, experimental works and theoretical analysis are presented to analyze
the influence of the conductor permeability on the precision of yokeless current sensors.
The results of finite-element method (FEM) fit ...
Inductance position sensor for pneumatic cylinder
(American Institute of Physics, 2018)
The position of the piston in pneumatic cylinder with aluminum wall can be measured
by external inductance sensor without modifications of the aluminum piston
and massive iron piston rod. For frequencies below 20 Hz the ...
