Borehole Seismic Survey 3 Channels Borehole Geophone Seismograph Downhole Shear Wave Seismic Survey Meter Borehole PS Reorder Seismic Velocity Tester


Features:

Perfect display of original signals---- Fine amplitude consistency and phase consistency, super-low distortion, advanced high-cut filter with suppression more than 72dB (cut point changes according to sampling frequency, without false frequency).

High-speed data transferring---- Data collection device and industrial PC (or notebook PC) are designed with USB ports, performance are much higher than other printer ports; sampling and data transferring can carry out simultaneously, owing to the advanced hardware.

Trigger signal is available at any time to get into sampling process, for background noise is always being monitored

Borehole Seismic Survey 3 Channels Borehole Geophone Seismograph Downhole Shear Wave Seismic Survey Meter Borehole PS Reorder Seismic Velocity Tester
Our down-hole three-component geophone, is a kind of electrodynamics velocity sensor, generally used to receive seismic waves down the hole. The geophone is made up from 3 high-sensitivity orthogonal Cartesian coordinates, which can sense the seismic wave from the 3-directions respectively. There is a air-lock device, being to suit for drilling well of a diameter of Φ50~Φ110 (if the diameter is more than Φ110, we will supply additional chock ).

Test equipment for shear wave - percussion plate excitation source will be a good elastic wooden board (board length of about 2 meters, width of about 0.4-0.5 meters, thickness of about 0.1 meters) subject to hammering of the two ends wrapped in iron plate, placed on a flat ground, pressed on top of a heavy object, so that the board and the ground in close contact, and then knocked on both sides of the board, so that the board to the ground A horizontal impact force, to excite the shear vibration of the soil layer. The excitation vibration is mainly SH wave.
