Low Noise Flux Gate FGS-03e: 3-Axis Fluxgate Sensor

Supplied By: Metronix Geophysics, Germany

FGS-03e Low Noise Flux Gate

The FGS-03e is a low noise 3-axis fluxgate sensor. It extends the frequency range for MT measurements down to DC. The FGS-03e provides automatic sensor detection with ADU07e systems. The sensor core unit is a Bartington Mag-03.

For lower frequencies all transfer functions are linear. This sensor is designed for crustal studies where periods of 10,000 seconds and more are needed. Recording time for those periods are three to eight weeks depending on the data quality (magnetic activity and external interferences by man made noise).
