Symmetrical Core Improves Micro-Fluxgate Sensors

By P. Ripka, S. O. Choi, A. Tipek, S. Kawahito and M. Ishida


Microfluxgate sensor with flat coil and double-sided symmetrical core has significantly improved parameters over the original asymmetric single-sided core design. The magnetic circuit of the new sensor is more closed and so the core is deeper saturated. The sensor hysteresis was decreased from 30 T to 2.5 T (for full range). Noise level was decreased from 242 nT to 27 nT rms (0.1 mHz to 10 Hz.). The sensor linear range was extended from 600 T to 1 mT. Perming was reduced from 50 µT to 5 µT after the field shock of 6 mT
