Borehole 3D Geophones
GFA 50/100 - PASI srl
3D borehole geo-phone is realized with 3x high sensitive geophones (nat.freq.10 Hz- 1 vertical and 2 horizontal sensors) oriented according to a triad of orthogonal Cartesian axes XYZ. Delivered with a cleat assembly to sustain its weight at the requested depth (GFA cable is graduated in meters), this borehole geophone has a pneumatic-mechanical clamping system.
