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.
