broad frequency sensors

AE Broad Band SensorAE Sensors that are ideal for:

  • Research or feasibility studies where the ideal frequency is unknown
  • Where different frequencies in one signal should be analysed (e.g. modal analysis)
  • Determining the correct frequency for your particular application
  • Waterproof model available (VS900-WIC-V01)

Vallen Systeme’s broad band, or wideband, frequency acoustic emissions sensors (AE) are characterized by two peaks at 190 kHz and 350 kHz with accompanying anti-resonances at 200 kHz and 400 kHz. Broad band frequency AE sensors combine a good response in the standard frequency – and high frequency range. Listed below are the available models, or contact us for assistance with your application.

vs900-m_300dpi_800x650pxVS900-M

The VS900-M is a passive piezoelectric AE-sensor that has a broad frequency response. Its response is characterized by two peaks at 190 kHz and 350 kHz with accompanying anti-resonances at 200 kHz and 400 kHz. Benefits of the VS900-M are a high sensitivity over a broad frequency range with compromises regarding the flatness of response. It combines a good response in the standard frequency – and high frequency range.

vs900-wic-v01_300dpi_800x650pxVS900-WIC-V01

The VS900-WIC-V01 is a piezoelectric AE-sensor with integrated preamplifier. Its response is characterized by two peaks at 190 kHz and 350 kHz with accompanying anti-resonances at 200 kHz and 400 kHz. Benefits of the VS900-WIC-V01 are a high sensitivity over a broad frequency range with compromises regarding the flatness of response. It combines a good response in the standard frequency – and high frequency range. The VS900-WIC is rated water tight up to 60 bar of water pressure and is suited for wet environments or for on-site monitoring of underwater installations. The integrated preamplifier has 34 dB gain and supports pulse through for automatic sensor testing.
