The VS150-RSC-V2 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.
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 Release R2018.0726.
Vallen Smart Line™ features: sensor type, serial number and gain are automatically identified and read by the AE system.
