Novel Giant Magnetoimpedance Magnetic Field Sensor

Piotr Gazda , Roman Szewczyk

Abstract

The idea, design, and tests of the novel GMI sensor are presented, based on the compensation measurement principle, where the local ‘zero‐field’ minimum of the double‐peak characteristic was utilized as a sensitive null detector. The compensation field was applied in real‐time with the help of microprocessor‐based, two‐step, quasi‐Newtonian optimization. The process of material parameters optimization through Joule‐annealing of chosen amorphous alloys is described. The presented results of the prototype test unit show linear output characteristic, low measurement uncertainty, and resistance against time and temperature drift.
