The VS12-E is a passive piezoelectric AE sensor. The very low frequency response makes it especially suited for monitoring large objects, objects made of highly attenuating material or leakage. The VS12-E can be used for leak detection in pipelines and integrity testing of concrete structures.

Remark to frequency response curve below: cable used RG 178 / 0.3 m. VS12-E has 6 dB less sensitivity if used with 1.2 m long cable.
