Abstract

Fluxgate sensors are common used in week and low frequency magnetic field measurements. Recently rapid development of miniature fluxgate sensors made in PCB technology is observed. Until now single core layer sensors were unable to measure magnetic field for two directions. Moreover no modelling results of influence of amorphous alloy chemical composition on sensor properties were available.

This paper presents results of tests of functional characteristics of miniature single tape ply fluxgate sensors with two kinds of chemical compositions of amorphous alloys cores: Fe67Co18Si1B14 and Co66Fe4Ni1Si15B14.

Sensors were made with seven layer printed board. Cores, which are produced using photolithography technology from single tape ply, has frame shape. Thus they are able to measure independent two perpendicular direction of magnetic field. Excitation and pick up coils are printed on board.

Experimental results shown strong dependence of sensor characteristics on chemical composition of core material. It proves that further investigation of material influence on sensor properties and optimisation of cores are strong desired.
