Micro-fluxgate sensor with closed core
Micro-fluxgate sensor with symmetrical core on both sides of the planar rectangular excitation and pick-up coils has substantially improved parameters compared to its single-core predecessor. Almost closed magnetic path for the excitation field allows much deeper saturation of the sensor core, which reduces the perming effect, hysteresis and noise. Perming of max. 5 μT for 6 mT field shock, 28 ...

متن کاملA 3-Axis Miniature Magnetic Sensor Based on a Planar Fluxgate Magnetometer with an Orthogonal Fluxguide
A new class of tri-axial miniature magnetometer consisting of a planar fluxgate structure with an orthogonal ferromagnetic fluxguide centrally situated over the magnetic cores is presented. The magnetic sensor possesses a cruciform ferromagnetic core placed diagonally upon the square excitation coil under which two pairs of pick-up coils for in-plane field detection are allocated. Effective pri...
متن کاملRace-track fluxgate with adjustable feedthrough
Improved shape of the race-track fluxgate sensor is suggested, which allows precise symetrization of the sensor and thus lower level of the feedthrough signal. The sensor has high untuned sensitivity (16.7 V/T per 1 turn) and low crossfield response thanks to the high shape anisotropy. The closed core and low cross-section guarantee low power consumption, low noise and stable offset. The sensor...
متن کاملFabrication of MEMS-based Micro-fluxgate Sensor with Runway-shaped Co-based Amorphous Alloy Core
High-precision magnetic micro-sensor is an interdisciplinary subject of magnetic field measurement techniques and micro-electromechanical systems (MEMS) technology. A micro-fluxgate magnetic sensor based MEMS technology was designed and fabricated in this paper. This device is a micro-magnetic sensor with a symmetric construction, closed magnetic circuits and differential form. A 25μm thick Flu...
