Magnetometer Datasheet - 58481 Single Axis Fluxgate Magnetometer

1 Axis Fluxgate Magnetomer Model FGM-3D2-xx

Features:

1 axis Fluxgate Magnetometer Modell FGM-3D2-L Portable, battery powered magnetometer 1 gamma (0.01 mGauss) resolution on 20 mGauss range ± 0.5% absolute accuracy traceable to NIST (Previously NBS) Three full-scale ranges: ±20, ±200, and ±2000 mGauss 3½ digit display Analog output ±2 V Noise <0.5 gamma Wide bandwidth 100 Hz CE Certified

Description:

The FGM single axis fluxgate magnetometers are rugged, accurate, highly sensitive portable hand held instruments for measuring DC magnetic fields from 1 gamma (1 nTesla) to 2 Gauss. These small and highly stable portable instruments, pow-ered by a conventional 9 volt alkaline battery, can meas-ure DC magnetic fields to an absolute accuracy of ±0.5% traceable to NIST, with linearity better than ±0.02% on all ranges. All Fluxgate Magnetometers FGM instruments have three ranges: ±20 mGauss, ±200 mGauss, and ±2000 mGauss. The 3½ digit LCD display (or optional 4½ digit display) provides a resolution of 0.05% (1 gamma on the 20 mGauss range). There are no zero or gain adjustments required. The flux-gate magnetometer design inherently results in very sta-ble and accurate performance. A buffered analog output is provided which can be used to drive a strip chart recorder or connect to a data acquisition system. The wide frequency response of DC to 100 Hz of the analog output allows the user to monitor fast moving magnetic signals and measure 50/60 Hz powerline fields. Typical applications include measuring ambient vectors, inspecting air shipment packages for compliance with FAA regulations, classroom demonstrations, calibrating laboratory field sources such as solenoids or Helmholtz coils, measuring weak fields in rocks, mapping and re-cording field perturbations caused by ferromagnetic ob- jects, measuring Earth's field vector components, deter-mining attenuation characteristics of magnetic shields and shielding materials, and evaluating effectiveness of mag-netically shielded rooms. The superior stability, linearity, and accuracy of the Flux-gate Magnetometer FGM compared to Hall effect devices make it the only choice for precision high quality low-level magnetic field measurement and the best choice for gen-eral purpose magnetometer applications. The Fluxgate Magnetometers FGM comes with either a longitudinal (L) or transverse (T) sensor. A neutralization (N) feature is available to null out ambient vectors from 0 to ±600 mGauss when conducting measurements outside of a shielded enclosure.

Applications:

Package inspection Classroom demonstrations Residual field measurements (shielding effectiveness) Solenoid/Helmholtz coil calibration Field Mapping Vehicle magnetic signature measurements Measure Earth's field vector components Magnetic environment monitoring Measure weak fields in rocks
