Spectral analyses used for fluxgate sensors with a computer aided measurement system

Summary form only given, as follows.The behaviour of a fluxgate sensor using amorphous alloy cores in a.c. magnetic field was studied using spectral analysis with the help of an computer aided measurement system and an adequate software. The characteristics obtained are linear for frequencies up to 5 kHz in the range 0-1.6/spl times/10/sup -4/ T.
