Mag639 Wide Bandwidth Magnetic Field Sensor

Mag639 Three-Axis Wide Bandwidth Magnetometer Mag639 Three-Axis Wide Bandwidth Magnetometer

This high bandwidth and high-performance three-axis fluxgate sensor provide precision measurements of DC and AC magnetic fields. With a noise level of <20pTrms/√Hz at 1Hz, and bandwidth of 12kHz, this sensor was initially designed for the detection of UXO using Time-Domain Electromagnetic prospection methods. It is now also being used in industrial application as part of EMC testing and environmental control systems.

Typical applications:
  • Environmental magnetic field monitoring in industry using high AC power.
  • Electromagnetic Compatibility testing.
  • Geophysics including time domain electromagnetic for UXO detection.

  • Features:
  • Frequency response from DC to 12kHz (-3dB).
  • Noise level of <20pTrms/√Hz at 1Hz.
  • Measuring range of ±100µT.

  • Export: This product is classified as military and requires an export licence for shipping outside of the UK. See the Export Licence page for further details.
