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:
single-channel single detector to receive the oil seismic signal
Resonance frequency: 3.2 (Hz)
Probing frequency region: 4-450 (Hz)
High Dynamic Range: more tha130dB
Velocity sensitivity: 225 (V/ms-1)
Damping ratio: 0.4
Nonlinearity: <0.1%
Output impedance: 5350 (Ω)
Size: Φ50×168 (mm)
Wight: 625 (g).
The figures as follows represent the results obtained by means of the traditional electromagnetic geophones, the MEMS geophones, as well as the novel magnetic suspension geophone. The Magnetic Suspension Geophone is the Best One.
