vs150-l_300dpi_800x650pxVS150-L

The VS150-L is a passive piezoelectric AE-sensor. Its frequency response is characterized by a peak at 150 kHz where it exhibits a resonance. It is suitable for almost all AE application. The VS150-L has a full metal housing that makes it especially suited for adhesively mounting it to a test object. In this respect it is suited for inspecting objects that have no ferro-magnetic surface such as composites and Al alloys.
