The VS375-WIC is a piezoelectric AE sensor with integrated preamplifier. Its frequency response is characterized by a peak at 375 kHz where it exhibits a resonance. The VS375-WIC is rated watertight up to 60 bar of water pressure. Its frequency response bridges the gap between standard frequency range and high frequency range. The VS375-WIC 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.
