Low Frequency Geophone 1Hz

Low frequency geophone 1Hz (P/N: ST-1N) 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-1N 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 200.0V/m/s.
1-year limited warranty on basic elements exclusive of high voltage, lightening or physical abuse.
