GS-14
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. |

| Notes: |
| 1. Reference temperature for functional parameters is
75°C |
| 2. Orientation angle is referenced to vertical. |
| 3. Damping factor is ratio of critical damping. |
4. Sensitivity, natural frequency, coil resistance and damping
factor are 100% tested. Consult the factory
for special tests required to guarantee other
functional parameters and shock limits. |
