FGM650

VERTICAL FLUXGATE GRADIOMETER

+/-10,000nT. +/-3,000nT. MAINTENANCE FREE.

The FGM650/10 is a vertical difference magnetometer with a standard measurement range of ±10 μT. It is used in various surface-, underwater- and borehole measurement systems for the detection of magnetic objects, interference fields and signatures in the ground.

The FGM650/10 consists of two single-axis Fluxgates that are aligned vertically to each other in a distance of 650 mm. This alignment allows for differential measurements thus suppressing the Earths magnetic field and global disturbances. The result is an improved detection of object signatures in the ground.

The FGM650/10s rugged aluminum housing makes the sensor also a suitable device for borehole measurements e.g. with the SENSYS MAGNETO® BM DISTLOG system with distance measurement.

Also available: FGM650/3 which features a measurement range of ±8 μT for applications in archaeology and geophysics. Thus even finest ground structures can be scanned.
