The VS375-M is a passive piezoelectric AE sensor. 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. It is especially suited for integrity inspection of high energy piping in conjunction with using a waveguide.
