VS75-SSC-34DB with Vallen Smart Line™ feature.
The VS75-SIC-34dB is an AE sensor with integrated preamplifier. Its frequency response is characterized by a peak at 75 kHz where it exhibits a resonance. The low frequency response makes it suited for monitoring large objects or objects made of highly attenuating material. The VS75-SIC-34dB can be used for integrity testing of bitumen coated pressure vessels and for detecting partial discharge. The integrated preamplifier has 34 dB gain and supports pulse through for automatic sensor testing.
