The VS375-RIC is a piezoelectric AE sensor with integrated preamplifier. Its frequency response is characterized by a peak at 375 kHz where it exhibits a resonance. Its frequency response bridges the gap between standard frequency range and high frequency range. The integrated preamplifier has 34 dB gain and supports pulse through for automatic sensor testing.
