high frequency sensors

AE NDT SensorAE Sensors that are ideal for:

  • Small samples or where mounting space is limited
  • Screw-in or glue-on models available
  • Monitoring the crimping process
  • Characterising paper during tensile tests
  • Sensors that can bridge between standard and high frequency ranges

Vallen Systeme’s high frequency acoustic emissions sensors measure in the range greater than 400 kHz. There are several different models available, depending on frequency and application. Listed below are the available models, or contact us for assistance with your application.

AE sensors nomenclature

Most Vallen Sensors are named systematically by its peak frequency and information about the case type and pre-amplifier information:

vs150-wic-v01_300dpi_800x650px
VS150-WIC-V01

The VS150-WIC is a piezoelectric AE-sensor with integrated preamplifier. Its frequency response is characterized by a peak at 150 kHz where it exhibits a resonance. The VS150-WIC is rated watertight up to 60 bar of water pressure. It is suitable for almost all AE application and especially 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.

vs700-d_300dpi_800x650px
VS700-D

The VS700-D is a passive piezoelectric AE-sensor with integrated cable. Its frequency response is characterized by a series of relatively flat peaks at 350 kHz, 600 kHz and 750 kHz with a limited response at 500 kHz. Its small size makes it especially suited for being mounted on small samples where mounting space is restricted. It was intended for characterizing paper during tensile tests and its mounting mechanism is optimized for this kind of task.
