BFD-400

Precise magnetic field measurement

The BFD-400 probes BFD-400-1 and BFD-400-3 - For precise magnetic field measurement The BFD-400-1 and BFD-400-3 probes extend the Narda probe family with powerful, isotropic sensors for measuring magnetic flux density in the frequency range from 1 Hz to 400 kHz. Both probes are ideal for precise measurements of low-frequency magnetic fields in a wide range of applications - from simple measurement tasks to demanding analyses in development, diagnostics and maintenance.

Features

Key capabilities and advantages

  • Isotropic (direction-independent) measurement with 100 cm² sensor or 3 cm² sensor.
  • Wide frequency range from 1 Hz to 400 kHz with high dynamic range of 70 dB.
  • Spectrum mode with displayed limit value curve.
  • Shaped time domain evaluation STD (WPM and WRM) for all relevant international standards and regulations such as Directive 2013/35/EU.
  • Adjustable narrow filter for the digital LF probes (bandpass or bandstop).
  • Scope mode for the temporal display of the LF field progression.
  • Digital probe interface - no more counter calibration.
  • Self-test of the probe interface with integrated sensor function test.
  • Wide temperature range.
