Sensor SM-6/H-B Style 4.5Hz Geophone

Sensor SM-6/H-B style 4.5Hz Geophone( P/N: ST-4.5B) is a low distortion geophone with high sensitivity of 80.0V/m/s. The SM-6/H-B style 4.5Hz Geophone( P/N: ST-4.5B) can be supplied for vertical and horizontal orientation, which is an ideal choice for the shear-wave horizontal elements, partnering the ST-4.5B vertical sensitivity geophone in a 3-component package.

  • High open circuit intrinsic voltage sensitivity of 80.0V/m/s.
  • Low harmonic distortion is no bigger than 0.3%.
  • Work in the direction of Vertical, Horizontal or Three component structure.
  • Rugged construction with precious-metal, rotating-coil contacts.
  • Suitable for vibration monitoring.
  • 3-year limited warranty on basic elements exclusive of high voltage, lightning or physical abuse.
