SISMA 120 VELOCIMETER S SISMA Seismometer has high performance triaxial with high sensitivity sensors designed for the creation of seismic and microseismic networks. The SISMA 120 (Seconds) is compact, reliable and easy to deploy and use. No need for calibration, it comes with calibration certificate with poles and zeroes detail. Wide tilt tolerance allows the unit to work within minutes from deployment. Differential output with high gain and high dynamic range allows the unit to be used with all kinds of seismic digitizers. The homogeneous architecture of SISMA 120(s) assures for each UUWV element high quality thanks to the standardized production line. Advanced selection of component´s materials from aluminum to titanium and special alloys, allows the maximum robustness and thermal stability. The following diagrams shows the noise floor of 0.01 Hz-40Hz sensors. APPLICATIONS • Seismic and microseismic networks Solgeo - Via Pastrengo, 9 - 24068 Seriate (BG, Italy)
