The VS30-SIC-46dB is a piezoelectric AE sensor with integrated preamplifier. The low frequency response makes it especially suited for monitoring large objects or objects made of highly attenuating material. The VS30-SIC-46dB can be used for tank floor corrosion and leak detection, leak detection in pipelines, partial discharge detection and integrity testing of concrete structures. The integrated preamplifier has 46 dB gain and supports pulse through for automatic sensor testing.
