GS-14 Industrial Geophone


Geo Space Corporation manufactures high quality, low cost geophones for a variety of industrial and military uses. These geophones have an unlimited shelf life and provide years of trouble-free service in applications where accurate motion sensing is required.

The GS-14 is a miniature, self-generating velocity detector designed for rugged environments. It withstands extreme shock with no change in performance characteristics. The GS-14 has been used as a reliable component in sonobuoys, smart fuses and intrusion detection systems.

The GS-14 is sensitive to motion along its longitudinal axis and is designed to operate in any position from vertical to horizontal. Both medium and high sensitivity models are available. With a natural frequency of 28 Hz, the GS-14 is an ideal motion sensor for frequencies in the acoustic spectrum.
