MAGNETIC SENSOR ARRAY FOR INVESTIGATIONS OF MAGNETIC FIELD DISTRIBUTION

Slawomir Tumanski – Slawomir Baranowski

   Various magnetic sensor arrays are described - GMR sensor array, Hall sensor array and AMR sensor array. The applications of this last one are presented. The sensor matrix was designed for three various purposes: a) for test of the steel strip in n × 16 points, b) for increase of the sensor output signal and to obtain the averaging effect, c) for improve of the speed of the scanning device.

Keywords: magnetic sensor, magnetic sensor array, scanning of magnetic fields, GMR sensors, AMR sensors
