The VS150-RSC is a piezoelectric AE sensor with integrated Vallen Smart Line™ preamplifier. Its frequency response is characterized by a peak at 150 kHz, where it exhibits a resonance. It is suitable for almost all AE application and especially suited for integrity inspection of metallic pressure vessels. The integrated preamplifier has 34 dB gain and supports pulse through for automatic sensor testing. The VS150-RSC supports the Vallen Smart Line™ protocol. Vallen Smart Line™ products are supported since AE Suite Software Release R2018.0726. Vallen Smart Line™ features: sensor type, serial number and gain are automatically identified and read by the AE system.
