QuSpin QTFM Gen-2 Total Field Magnetometer
QuSpin QTFM Gen-2 Total Field Magnetometer
New-Sense Geophysics uses the QuSpin QTFM Gen-2, a new-generation optically pumped total field magnetometer that is compact, lightweight and very sensitive. The QTFM2 is mounted in our fixed stinger assemblies and in our base stations, and delivers high-resolution magnetic data for both airborne and ground reference measurements.
Key Features of QuSpin QTFM2 Magnetometer:
- Ultra-High Sensitivity:The QTFM2 has a scalar sensitivity of less than 3 pT/√Hz, well within the 0.01 nT resolution required for high-quality airborne magnetic surveys. It resolves subtle magnetic variations related to geology, structure and mineralization.
- High-Frequency Data Acquisition:Raw magnetic data are recorded at 250 Hz, smoothed with a 51-point cosine filter and resampled to 10 Hz (0.1 s sampling interval). The result is a clean, well-sampled profile along each survey line.
- Low Noise and Low Heading Effect:The sensor keeps a tight noise envelope of 0.01 nT and a heading effect below 2.0 nT, which compensation and heading corrections reduce further during processing.
- Wide Operating Range:The QTFM2 operates in ambient fields from 20,000 nT to 100,000 nT, so it can be deployed anywhere in the world, from equatorial to polar regions.
- Integrated Orthogonal Outputs:Besides the total field, the QTFM2 records orthogonal X, Y and Z components. These support aircraft compensation and data quality control.
- Compact, Lightweight Design:Its small size and low weight make it easy to mount in fixed stinger assemblies and base stations without sacrificing measurement performance.
- Proven in NSG Operations: The QTFM2 is part of NSG’s current survey systems, used in multiple recent projects executed in high altitude mountainous terrain.
