High Sensitivity Geophone 1Hz

Low frequency and high sensitivity geophone 1Hz  (P/N: ST-1A) in  vertical direction (P wave) and horizontal direction (S wave) are available. They are suitable for deep seismic exploration, engineering pulse measurement and other vibration analysis.

  • Long travel version of the ST-1A geophone, with Max. coil excursion p-p 6.0mm.
  • Special orientations upon request beyond the normal vertical and horizontal options.
  • Widely used in industrial vibration-monitoring systems.
  • Rugged construction with precious-metal, rotating-coil contacts.
  • High sensitivity of 650.0V/m/s.
  • 1-year limited warranty on basic elements exclusive of high voltage, lightening or physical abuse.
