The VS150-WSC-V01 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 VS150-WSCV01 is rated watertight up to 60 bar of water pressure with connected cable. It is suitable for almost all AE applications and especially suited for wet environments or for on-site monitoring of underwater installations. The integrated preamplifier has 34 dB gain and supports pulse through for automatic sensor testing. The VS150-WSC-V01 supports the Vallen Smart Line™ protocol. Vallen Smart Line™ products are supported since Vallen AE-Suite Software Release R2018.0726. It can be also used with software or devices not supporting the Vallen Smart Line™ protocol – then without the Vallen Smart Line™ features. Vallen Smart Line™ features: sensor type, serial number and gain are automatically identified and read by the AE system AMSY-6.
