This geophones for oil and gas exploration and vibration monitoring, it is on the basis of the principle of magnetic suspension. And it is lighter, easy to move and high precision.
Because no spring is needed in the magnetic suspension geophones, the novel geophone is very sensible and covers a wide frequency range of monitoring. One magnetic suspension sensor is capable of replacing parallel and series combinations of several electromagnetic geophones. The technical parameters are listed as followings:
Resonance frequency: 3.2 (Hz)
Probing frequency region: 4-450 (Hz)
Velocity sensitivity: 225 (V/ms-1)
Damping ratio: 0.4
Nonlinearity: <0.2%
Output impedance: 5350 (Ω)
Size: Φ50×168 (mm)
Wight: 625 (g).
