High Sensitivity Geophone 5Hz

High sensitivity geophone 5Hz(P/N:ST-5NA) is a long coil travel version geophone with high sensivitivy of 80.0V/m/s. The extra coil travel offers an advantage for higher tilt requirements and where larger amplitude signals may be encountered, for example, in industrial vibration monitoring.

The ST-5NA geophone can be supplied for vertial and horizonta orentation, which is an ideal choice for the shear-wave horizontal elements, partnering the ST-5NA high sensitivity geophone in a 3-component package.

  • Long travel version of the ST-5NA geophone.
  • Special orientations upon request byond the normal verical and horizotnal options.
  • Widely used in industral vibration-mnitoring systems.
  • Ideal choice for shear-wave horizontal elements.
  • Rugged construction with precious-metal, rotating-coil contacts.
  • High open circuit intrinsic voltage sensitivity of 80.0V/m/s.
  • 2-year limiated warranty exclusive of high voltage, lightenting or physical abuse.
