LE-3D/5s ~ Lennartz 3 Directional 5 seconds geophone


  The LE-3D/5s three directional geophone is based on a patented electronic circuitry that transforms the output of 2 Hz geophones to a 0.2 Hz (5 seconds) characteristic.

Additional advantages of LE-3D/5s sensors are:

  • Less sensitivity to improper leveling than conventional mechanical designs.
  • Simplified data processing due to identical sensitivity for all components and all geophones.
  • No need for external damping due to internal damping to 0.7 critical; low resistance output.
