SS08BH
SS08BH is a triaxial broad-band seismometer designed installation in boreholes. This solution offers automatic levelling and motorised hole-lock system, wide temperature operations and safe transport. The sensor uses the symmetric architecture recovering Z,Y,X velocity signal from U,V,W homogeneous transducers; this methodology allows higher precision in reconstruction of real ground motion.
- Small diameter to fit 100mm boreholes (4 inches)
- Hole lock mechanism to use the sensor at any hole deep
- Auto levelling mechanism to compensate up to +/-5°
- Ultra low noise design
- Fast setup, data are useable few minutes after deployment
- Intrinsic robustness
- Low power consumption allows unit to be used in remote installation with limited energy source
- Possibility to have embedded digitizer with accurate sync
- Detachable cable for easier transportation
